Java debug mode: how to get return value of function call [duplicate]

Question

The variable view of the Eclipse Java Debug mode allows to inspect the values of variables. What I'm frequently missing is to inspect the return value of methods: if such a return value is not stored into a variable but immediately used to call one of its methods, it is not visible in the debugger.

For example, consider foo.getBar().equals("xxx"); where getBar() yields a String. If the source of foo is unavailable, how can the result of getBar() be inspected before the call to .equals()? Of course, one can change the code by introducing a local variable that holds the result. But that is too unpractical in general.

Answer 1

You can select the expression to inspect (in this case select foo.getBar()), then right-click and select "Inspect", or type the shortcut Ctrl+Shift+i. The side effect is that it will execute the method, so changes done in the method on, say, member fields will be applied.
