You can follow the steps below:

&gt;1. Run -&gt; View breakpoints -&gt; Add -&gt; Java Method Breakpoints
&gt;
&gt;2. Class pattern -&gt; full reference of your class *(e.g., mypackage.MyClass)*
&gt;
&gt;3. Method Name -&gt; * *(i.e., asterisk wild card)*

I have discovered workaround :
&lt;br/&gt;&lt;br/&gt;1. I have set &quot;Toggle Brakepoint&quot; hotkey to &lt;kbd&gt;Alt&lt;/kbd&gt;+&lt;kbd&gt;Numpad 0&lt;/kbd&gt;.
&lt;br/&gt;2. After that you can click on first method
&lt;br/&gt;3. Use &quot;Toggle Brakepoint&quot;
&lt;br/&gt;4. &lt;kbd&gt;Alt&lt;/kbd&gt;+&lt;kbd&gt;Down&lt;/kbd&gt; - goto Next Method. ( &lt;kbd&gt;Alt&lt;/kbd&gt;+&lt;kbd&gt;Up&lt;/kbd&gt; - goto Previous Method. )
&lt;br/&gt;5. Repeat 3 step.

This is similar to Sergey Senkov&#39;s answer, but without hotkeys.

In the structure view, click on the first method. Repeat the following for each method:

1. &lt;kbd&gt;Context Menu Key&lt;/kbd&gt;
2. &lt;kbd&gt;M&lt;/kbd&gt; to toggle the method breakpoint.
3. &lt;kbd&gt;Down&lt;/kbd&gt;

There is a plugin for idea:
[Simple Toggle All Method Breakpoint][1].

It allows you to breakpoint all methods / clear all method&#39;s breakpoints in one click from context menu on class in Project view.


  [1]: https://plugins.jetbrains.com/plugin/9661-simple-toogle-all-method-breakpoint

As Andrey Lavrukhin suggested, there is *Simple Toggle All Method Breakpoint*, install it through Settings -&gt; Plugins. Works perfectly.

The only way you&#39;ll be able to do what you want is to set method breakpoints on each and every method with the class in question.  You need to click on the left hand gutter next to the method - a little red circle with 4 dots will appear and you may get a warning saying method level breakpoints can impact performance.  You can then further configure the breakpoint (by rightclicking on it, or select shift+F8) and set it so that it breaks on entry, exit or both 

I&#39;m afraid theres no way to do this in a single step/setting.

[`element.classList`](https://developer.mozilla.org/en-US/docs/DOM/element.classList) is of [`DOMTokenList`](https://developer.mozilla.org/en-US/docs/DOM/DOMTokenList) type.

Is there a method to clear this list?

My question is simple: I have a python script that generates figures using matplotlib. Every time i run it it generates new windows with figures. How can I have the script close windows that were opened the previous time it ran?

the analogous command in matlab is to put &#39;close all&#39; at the beginning of your matlab script.

I have seen several suggestions to do something like

    import matplotlib.pyplot as plt
    plt.close(&quot;all&quot;)

This solution works if you run your script from the python shell, eg using

    &gt;&gt;&gt;&gt; execfile(&quot;myScript.py&quot;)

However, I have found that this doesn&#39;t work if I run the script using Eclipse / PyDev. How can I get it to work in Eclipse?



example:

    from numpy import *
    from matplotlib.pyplot import *
    from scipy import *

    close(&quot;all&quot;) 
        #close any previously open plots - this doesn&#39;t work when running via Eclipse

    t = linspace(0, 0.1,1000)
    w = 60*2*pi

    figure()
    plot(t,cos(w*t))
    plot(t,cos(w*t-2*pi/3))
    plot(t,cos(w*t-4*pi/3))
    show()

This should plot the ideal waveforms for a nice 3-phase power supply.

Is there any way to set breakpoints on all methods of a given class?

I have a huge (2300 lines) legacy class and I need to set breakpoints on all method calls to understand how this mess works.

The more I read, the more confused I am. 

Note that all the question is related to how service and facades fit on the MVC pattern.

My understanding is that a Facade is not a super-smart object, it is simply a way of exposing a simple interface/api to perform a complex operation (example: perform a 10$ payment, it is a complex operation that involves a number of operations, but such complexity can be handled by a facade which will just call the corresponding object in a particular order...etc...)

Now, a service is a way to perform calls to several DAOs in order to get complex data structures (I am not too sure of this, but it is what I understand so far).

Question then is, what is the difference between a facade and a service? At the end of the day, the facade can perfectly access several DAOs in order to perform a complex operation by providing a simple interface, and a service seems to to something similar.

Same happens with transactions, I understand that a service is the place to start transactions, but I equally feel that they could also be placed on facades, after all, a facade may call several DAOs too. 

So which stack would make more sense

controller-facade-dao 
controller-service-dao

or maybe

controller-facadade-dao AND sometimes controller-facade-service-dao ??


Are the roles of a service and a fa&#231;ade similar?

    @POST
    @Path(&quot;/getphotos&quot;)
    @Produces(MediaType.TEXT_HTML)
    public String getPhotos() throws IOException{
	    // DataInputStream rd = new DataInputStream(request.getInputStream());
	    BufferedReader rd = new BufferedReader(
            new InputStreamReader(request.getInputStream(), &quot;UTF-8&quot;)
        );
		String line = null;
		String message = new String();
		final StringBuffer buffer = new StringBuffer(2048);
		while ((line = rd.readLine()) != null) {
            // buffer.append(line);
			message += line;
        }
		System.out.println(message);
		JsonObject json = new JsonObject(message);
		return message;
	}

The code above is for my servlet. Its purpose is to get a stream, make a a Json file from it, and then send the Json to the client back.
But in order to make Json, I have to read `BufferedReader` object `rd` using a &quot;while&quot; loop. However I&#39;d like to convert `rd` to string in as few lines of code as possible. How do I do that?

I have used [Java Mail API][1], for sending emails. I am using a contact formular to send the input, which has to be send to a specific email.

The email is send without problems, though I am a danish guy, and I am therefore in need of three danish characters which is &#39;&#230;&#39;, &#39;&#248;&#39; and &#39;&#229;&#39;, in the subject and the email text.

I have therefore seen that I can use UTF-8 character encoding, to provide these characters, but when my mail is send I only see some strange letters - &#39;&#227;&#166;&#39;, &#39;&#227;&#184;&#39; and &#39;&#227;&#165;&#39; - instead of the danish letters - &#39;&#230;&#39;, &#39;&#248;&#39; and &#39;&#229;&#39;.

My method to send the email is looking like this:

    public void sendEmail(String name, String fromEmail, String subject, String message) throws AddressException, MessagingException, UnsupportedEncodingException, SendFailedException
    {
        //Set Mail properties
        Properties props = System.getProperties();
        props.setProperty(&quot;mail.smtp.starttls.enable&quot;, &quot;true&quot;);
        props.setProperty(&quot;mail.smtp.host&quot;, &quot;smtp.gmail.com&quot;);
        props.setProperty(&quot;mail.smtp.socketFactory.port&quot;, &quot;465&quot;);
        props.setProperty(&quot;mail.smtp.socketFactory.class&quot;, &quot;javax.net.ssl.SSLSocketFactory&quot;);
        props.setProperty(&quot;mail.smtp.auth&quot;, &quot;true&quot;);
        props.setProperty(&quot;mail.smtp.port&quot;, &quot;465&quot;);
        Session session = Session.getDefaultInstance(props, new javax.mail.Authenticator() {
            @Override
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(&quot;my_username&quot;, &quot;my_password&quot;);
            }
        });

        //Create the email with variable input
        MimeMessage mimeMessage = new MimeMessage(session);
        mimeMessage.setHeader(&quot;Content-Type&quot;, &quot;text/plain; charset=UTF-8&quot;);
        mimeMessage.setFrom(new InternetAddress(fromEmail, name));
        mimeMessage.setRecipient(Message.RecipientType.TO, new InternetAddress(&quot;my_email&quot;));
        mimeMessage.setSubject(subject, &quot;utf-8&quot;);
        mimeMessage.setContent(message, &quot;text/plain&quot;);
        
        //Send the email
        Transport.send(mimeMessage);
    }

Please help me find out how I can correct this &#39;error&#39;.

I have a program that shows you whether two words are anagrams of one another. There are a few examples that will not work properly and I would appreciate any help, although if it were not advanced that would be great, as I am a 1st year programmer. &quot;schoolmaster&quot; and &quot;theclassroom&quot; are anagrams of one another, however when I change &quot;theclassroom&quot; to &quot;theclafsroom&quot; it still says they are anagrams, what am I doing wrong?

```java
import java.util.ArrayList;
public class AnagramCheck {
    public static void main(String args[]) {
        String phrase1 = &quot;tbeclassroom&quot;;
        phrase1 = (phrase1.toLowerCase()).trim();
        char[] phrase1Arr = phrase1.toCharArray();

        String phrase2 = &quot;schoolmaster&quot;;
        phrase2 = (phrase2.toLowerCase()).trim();
        ArrayList&lt;Character&gt; phrase2ArrList = convertStringToArraylist(phrase2);

        if (phrase1.length() != phrase2.length()) {
            System.out.print(&quot;There is no anagram present.&quot;);
        } else {
            boolean isFound = true;
            for (int i = 0; i &lt; phrase1Arr.length; i++) {
                for (int j = 0; j &lt; phrase2ArrList.size(); j++) {
                    if (phrase1Arr[i] == phrase2ArrList.get(j)) {

                        isFound =;
                        phrase2ArrList.remove(j);

                if (isFound == false) {

I have a project in IntellijIDEA which was created with Maven.  I then specified a set of dependencies and external repositories in the Pom.xml file.

The project builds fine on command line if I do &quot;mvn install&quot;.  When I open any of the code files in the IDE though it says all the classes handled by Maven dependencies aren&#39;t recognized - as it would for a normal project if I never added the required JARs to the build path.

I know in my Eclipse Maven projects (rather than IntelliJ) it usually shows an extra directory on the left which says &quot;Maven Dependencies&quot; and lists the JARs pulled in via maven.  I don&#39;t see that here.  What am I doing wrong?

While hunting through some code I came across the arrow operator, what exactly does it do? I thought Java did not have an arrow operator.

    return (Collection&lt;Car&gt;) CollectionUtils.select(listOfCars, (arg0) -&gt; {
            return Car.SEDAN == ((Car)arg0).getStyle();
    });

***Details**: Java 6, Apache Commons Collection, IntelliJ 12* 

***Update/Answer:** It turns out that IntelliJ 12 supports Java 8, which supports lambdas, and is &quot;folding&quot; Predicates and displaying them as lambdas. Below is the &quot;un-folded&quot; code.*

    return (Collection&lt;Car&gt;) CollectionUtils.select(listOfCars, new Predicate() {
        public boolean evaluate(Object arg0) {
            return Car.SEDAN == ((Car)arg0).getStyle();
        }
    });

I have the problem mentioned in the title. You could say that this thread duplicates another one: [How do I turn off error validation for annotations in IntelliJ IDEA?](https://stackoverflow.com/questions/1525947/how-do-i-turn-off-error-validation-for-annotations-in-intellij-idea)


But the solution given there doesn&#39;t work. They say that I need to take the following action:

&gt; In the Project Structure | Project dialog, change the Project language Level to 6.0 - @Override in interfaces.

However, the Project language Level is 6.0 at the moment, but I still see the error.


Vic, here is the window and there is no JVM version right under Language level (unfortunately I can&#39;t post images because I have 10 reputation)
