I was trying to get this java program to return 2. Why can't I type wait(); in main to do this?

I have an unrelated constructor (to this task of returning 2), and I've tried making an object in main to make it work but that didn't help.

Would a related constructor or method help? Do I have to initialize variables at the top of the class to accomplish this every time? Thanks for the help

    Please do not post images of code (or errors). Instead, add the code to the question itself as code-formatted text. The example code should preferably be a [mre]; case in point, I can't see anything wrong with the method shown in your image which likely means the problem is in code you haven't provided. Also, please include the _exact error message_ you're getting (also as text, not an image). You can [edit] your question to make improvements. – Slaw May 16 '20 at 06:01

    Turns out the image does show at least one problem, as demonstrated by QuickSilver. However, for future reference, please make sure to provide a [mre] demonstrating the problem, the exact error(s) you're getting, and in general make sure your question meets the standards outlined in [ask]. Remember, ideally your question should also be helpful to others in the future, not just yourself right now. – Slaw May 16 '20 at 06:11

Below are the problems with the code in the image

  • By default all class eventually end up extending Object class
  • You cannot override a final method. wait() is final method in Object class
  • Even though static method are class levels methods they cannot override instance method

Below is the method from Object class

public final void wait() throws InterruptedException {
        wait(0);
    }
