Like firebug for debugging javascript,
is there such a feature in eclipse? or do I need a plugin?

A:
I believe that what you're looking for are "watch expressions". Just mark the piece of code in the source code view, right-click and select "Watch".

You can also use the "Display" view to execute any code while you're debugging.

I saw that,but there is no response after I typed "System.out.println('test');" into it.

How to make it echo some result just under the Display view?

"watch expressions" works!

If you highlight the expression in the Display view (which also allows content assist, btw), you can right-click and choose "inspect" (runs the expression and brings up an inspector tree on the result), "execute" (runs the expression), and "display" (runs the expression and prints the result)

why cant it run without highlight the expression?

A:
You can use the Display view to execute commands while debugging. You can find this in Window -> Show View -> Display

you can use the 'Display' view to evaluate expressions in eclipse.
Look under the debug list of views. It is a standard par part of the java tooling so you don't need a plugin

But there is nothing echo back,after I type something like "path.length",where path is a String[]

as far as I remember (not using eclipse at the moment) you click on the run button and the result of the last expression is displayed.

I think @banjollity actually has a copy of eclipse open :-) I'm just flandering around in my memory...is now a good time to recommend Intellij

A:
Use the Display view, or a bit quicker: highlight the code you want to run and right-click/Execute or Ctrl+U.

Alternatively to "Execute", use Display (Ctrl+Shift+D) or Inspect (Ctrl+Shift+I) to see the result.

You can also create a scrapbook page (a .jpage) file and type your code in there. Then click run. It looked slightly more convenient when I tried it.
