This happend to me too.

For some reason Kepler changes the settings for Content Assist on Juno workspaces. Checking the `Java Proposals` checkbox in `Preferences -&gt; Java\Editor\Content Assist\Advanced` should resolve this problem.

My workaround to this problem: it seems that some component of Eclipse Kepler doesn&#39;t like workspace from older Eclipse version. Starting Eclipse with new workspace and reimporting projects solved the problem.

I&#39;m looking for something to achieve the following:

    String s = &quot;hello {}!&quot;;
    s = generate(s, new Object[]{ &quot;world&quot; });
    assertEquals(s, &quot;hello world!&quot;); // should be true

I could write it myself, but It seems to me that I saw a library once which did this, probably it was the slf4j logger, but i don&#39;t want to write log messages. I just want to generate strings.

Do you know about a library which does this?

I have seen a lot of comparisons which says select have to walk through the fd list, and this is slow. But why doesn&#39;t epoll have to do this?

Why is epoll faster than select?

I have been using OpenJDK for ages, initially for small projects where it has no problems. But since I started to play with it for big toys, I started to notice random/unknown fatal error and crashes (with H.264 codecs, etc.), and it was a nightmare till then to get ride of system crash+fatal errors caused by OpenJDK.

After getting completely frustrated and tired with OpenJDK, I finally decided to switch into Oracle JDK 7. Since then my fatal errors/crashes were gone. I am still doing trace to see if it occurs, but I never got those system crashes yet.

Now I am wondering, if OpenJDK is only a license issue, why is stability impossible with it?

Why does OpenJDK keep bugs alive, inside their stable releases, but claiming that its clone of Oracle JDK (which it is not really), then what really technically separates OpenJDK from Oracle JDK? (only quick features availability? Or focused on stability/reliability?)



Technically what is the main difference between Oracle JDK and OpenJDK?

I&#39;m verifying with mockito that a method has been called. The method:

    public void createButtons(final List&lt;Button&gt; buttonsConfiguration) {...}

Since It doesn&#39;t matter which list is passed I verify that the method is called as follows:

    verify(mock).createButtons(Matchers.anyListOf(Button.class));

But, the size of the `List` is important. So, it doesn&#39;t matter which `List` but the list has to have X elements.

Is that possible at all?

There are similar questions out there, but they seem to avoid answering this specific question.  How can I get the memory that **my Java program** uses via Java&#39;s Runtime api?

**The answer [here][1] indicates that I can do something like this:**

    System.out.println(&quot;KB: &quot; + (double) (Runtime.getRuntime().totalMemory() - Runtime.getRuntime().freeMemory()) / 1024);

But this always returns the same number, no matter which program I run.  For example, below I have a program where no matter how many numbers I put in the map, the memory usage stays the same.

    package memoryTest;
    
    import java.util.HashMap;
    import java.util.Map;
    
    public class MemoryTest {
    
        static Map&lt;Integer, NewObject&gt; map = new HashMap&lt;Integer, NewObject&gt;();
    
        public static void main(String[] args){
    
            System.out.println(&quot;KB: &quot; + (double) (Runtime.getRuntime().totalMemory() - Runtime.getRuntime().freeMemory()) / 1024);
            fillMemory(25);
    
            System.out.println(&quot;KB: &quot; + (double) (Runtime.getRuntime().totalMemory() - Runtime.getRuntime().freeMemory()) / 1024);
        }
    
        static int j=0;
        public static void fillMemory(int i){
    
            for(int k=0; k&lt; 2000; k++)
                map.put(j++, new NewObject());
    
        }
        
    
        public static class NewObject{
            long i = 0L;
            long j = 0L;
            long k = 0L;
        }
        
    }

via cambecc&#39;s main method, output is:

There are two types of iterators in Java: fail-safe and fail-fast.

What does this mean, and is the difference between them?

I&#39;m trying to learn android development and I am initially confused by the different project structures between Eclipse and Android Studio. This makes it difficult to follow tutorials designed for Eclipse. Could anyone let me know why these differences exist? Should they exist?

For instance, if I were to locate the R.java file in the two different IDEs, the paths would look like this:

**Eclipse:** app\gen\com.example.app\R.java


**Android Studio:** app\build\source\r\debug\com.example.app\R.java

Why are these paths different? Why is my R.java located in a  debug folder in Android Studio? This lead to some errors early on, and if anyone has any insight into these differences I would appreciate them.

When I change a setting in a window like in the screenshot below, where are those settings actually stored?

Bonus: Is there any way, using Java, Eclipse RCP etc, to access the settings programmatically?

Thanks!

EDIT: It turns out this really isn&#39;t specific to Eclipse Kepler. I had to use the same process for Eclipse Juno. The problem was that there seem to be missing steps in other posts answering this same question.

I&#39;m using Eclipse Kepler for C++ and I&#39;m trying to use C++11 and getting errors. When I compile I get the error

error: range-based-for loops are not allowed in C++98 mode

I&#39;ve followed the instructions from the post

https://stackoverflow.com/questions/9131763/eclipse-cdt-c11-c0x-support

and the solution given for Eclipse Juno isn&#39;t working. 

Different comments have suggested restarting eclipse and cleaning and rebuilding. That hasn&#39;t made a difference.

I&#39;m working on a Java project in Eclipse, which is built using Maven. I&#39;m using some recycled code from an older project, and one of these classes looks for a file in the `META-INF/services` folder of the JAR with a particular name, then parses the text of this file. In this particular example, it looks for a file with the name of a Java interface, then grabs the class name of the implementation from inside the file.

So basically what I&#39;m trying to do is **include a file in the &quot;META-INF/services&quot; folder of the JAR with a file name (X), and one line of text (Y)**. I&#39;m guessing this should be done using Maven, maybe by specifying an attribute in the POM file, but my research hasn&#39;t turned up anything. I know you&#39;re not supposed to hard-code or manually type out any META files, so I&#39;m not sure what to do here.

I have code in Eclipse that I&#39;d like to upload to GitHub but so far I can&#39;t figure out how. It says &quot;create a repository&quot; but that looks more like a folder that holds your projects and I&#39;m not sure how to upload my code to it. Apologies for the seemingly dumb question. Also, how does one delete repositories? Didn&#39;t see a way to do that either.
