How to use conditional breakpoint in Eclipse?

JavaEclipseDebuggingConditional Breakpoint

Java Problem Overview

I want to know how to place a conditional breakpoint in Eclipse. I have a code like:

public static void doForAllTabs(String[] tablist){
    for(int i = 0; i<tablist.length;i++){
-->        doIt(tablist[i]);

Now I want to put a breakpoint on the line with the arrow but want it to trigger only if:

Solution 1 - Java

Put your breakpoint. Right-click the breakpoint image on the margin and choose Breakpoint Properties:

Configure condition as you see fit:

Solution 2 - Java

Make a normal breakpoint on the doIt(tablist[i]); line

Right-click -> Properties

Check 'Conditional'

Enter tablist[i].equalsIgnoreCase("LEADDELEGATES")

Solution 3 - Java

1. Create a class

public class Test {

 public static void main(String[] args) {
	// TODO Auto-generated method stub
	 String s[] = {"app","amm","abb","akk","all"};
 public static void doForAllTabs(String[] tablist){
     for(int i = 0; i<tablist.length;i++){

2. Right click on left side of System.out.println(tablist[i]); in Eclipse --> select Toggle Breakpoint

3. Right click on toggle point --> select Breakpoint properties

4. Check the Conditional Check Box --> write tablist[i].equalsIgnoreCase("amm") in text field --> Click on OK

5. Right click on class --> Debug As --> Java Application

Solution 4 - Java

From Eclipsepedia on how to set a conditional breakpoint:

> First, set a breakpoint at a given location. Then, use the context > menu on the breakpoint in the left editor margin or in the Breakpoints > view in the Debug perspective, and select the breakpoint’s properties. > In the dialog box, check Enable Condition, and enter an arbitrary Java > condition, such as list.size()==0. Now, each time the breakpoint is > reached, the expression is evaluated in the context of the breakpoint > execution, and the breakpoint is either ignored or honored, depending > on the outcome of the expression. > > Conditions can also be expressed in terms of other breakpoint > attributes, such as hit count.

Solution 5 - Java

A way that might be more convenient: where you want a breakpoint, write a if statement and set a breakpoint in its contents.

if(tablist[i].equalsIgnoreCase("LEADDELEGATES")) {
-->    int breakpoint = 0; //don't do anything

(the breakpoint is represented by the arrow)

This way, the breakpoint only triggers if your condition is true. This could potentially be easier without that many pop-ups.

Solution 6 - Java

There are Simple step which you need to follow to trigger the conditional breakpoint.

Step 1- Put the breakpoint on that line which you want to be run when the breakpoint condition falls True (Now the question arises where to put the breakpoint condition)

Step 2- After putting the breakpoint simply right click on the small breakpoint image placed on the left margin of your code.

Step 3- After clicking you will find an some options click on the breakpoint properties.

Step 4- After clicking you will find checkbox i.e Conditions, simply check it

Step 5- There will be text box Enable in which you need to write the condition upon which the line which has breakpoint will have been executed only when the condition falls true
