While debugging, I often find it necessary to check the return value. Does
ecplise debugger provides someway to check the return value immediately
before the function return? Thanks a lot

You can evaluate any expression in the debugger by highlighting it and pressing 'Display' (or 'Inspect') if you need an inspector. However, since this evaluates the expression again, if there is any state change that occurs then you might get weird behaviour.

You can also use 'watch' expressions, which are the value of an expression that gets updated as the stack trace is stepped through. Again, watch out for methods that have side-effects if you're using this.

I don't believe there's any way of finding out what the return value specifically is, unless you're in the caller stack and do 'evaluate' on the expression called after return.
