Question

when developing C++ with VS you have this amazing feature of data breakpoints, which trigger when the data at a certain address in memory changes.

is there a similar feature when developing java in eclipse?

thanks!

edit: about the “suspend when value changes” feature: i have the impression that the execution must still reach the line where the breakpoint is. the thing is i want it to trigger anywhere as soon as the value changes.

You can set a watchpoint on a field: put the cursor at the line where the field is being declared and select the menu Run -> Toggle Watchpoint
or just set a breakpoint by double-clicking at the left margin on that line.

You can change the properties of the watchpoint like suspend on field access or suspend on field modification after adding it. Just right-click on the watchpoint at the left margin and select Breakpoint Properties...

Search the help for watchpoint to get more information:

A watchpoint is a special breakpoint that stops the execution of an application whenever the value of a given expression changes, without specifying where it might occur. …
