quick java question

im currently learning stacks in java and have a quick question. what will the following code display if the stack is empty? my guess would be "true"?

System.out.开发者_如何转开发println(st.isEmpty());

Yes, it will print true.

Running simple snippets of code is very easy (with IDEs like Eclipse - even easier), so you can verify all such assumptions with a few clicks/keystrokes.

In the future, give .jpage files a try. They provide a way in Eclipse to run small snippets of code as though they were being interpreted!

If you want to test out small snippets of code, try http://ideone.com!

Yes, it will simply return true. IsEmpty() method will return true, if no objects is available in stack container.

Stack s1 = new Stack();
    s1.push(1);
    s1.push(2);
    s1.push(3);

    s1.pop();
    s1.pop();
    s1.pop();
    System.out.println(s1.isEmpty());
