View variable contents in the Eclipse IDE

Question

How can I view the contents of several variables (e.g. TreeSet) at the same time? I can view the contents of one TreeSet by clicking on it in the Variables window, but I don’t know how to do this for several variables.

Answer 1

You can use the "Expressions" windows: during debugging, in the menu window → "View" → "Expressions", then it has a place to enter variables from which you need to see the contents

Answer 2

You can add a watchpoint for each variable you are interested in.

A breakpoint is a special breakpoint that stops an application from executing whenever the value of a given expression changes, without specifying where this might occur. Unlike breakpoints (which depend on a particular line), watchpoints are associated with files. They take effect whenever the specified condition is true, regardless of when and where it occurred. You can set the watchpoint on a global variable by highlighting the variable in the editor or selecting it in the Structure view.

This video perfectly shows you how to set breakpoints and view variables in Eclipse Debugger. http://youtu.be/9gAjIQc4bPU

Answer 4

You can do this in the following ways.

Add a watchpoint and during debugging you can see the variable in perspective of the debugging debugging window under the tab of variables. OR Add System.out.println("variable = " + variable); and see the console.
