Question

Is there a way to end the method that calls on the method that the code is in. Let me explain if you have some code like this.

int value;
value = method();
value = 3;

If I got it work like I want then the execution of the code would end on line 2 and line 3 would never be executed. basically it would be like there was a return between line 2 and 3. Is is something like this possible with Java?

Edit: Ok i think a lot of people have misunderstood me. The code that end the code on in this method on line 2 should be inside of method() and it should not be possible to avoid this outside this method if it’s call inside of a try for example.

Your example is a bit abstract, a real one might result in better answers. In general though there are two ways this is normally achieved:

1. Return a special value e.g. -1

   int method() {
       if (/* something is wrong */) {
           return -1;
       }
   
       // Process as normal and return real value
   }
   
   ...
   
   int value;
   value = method();
   if (value == -1) {
       value = 3;
   }
   

2. Throw an exception in method()

   int method() throws IllegalStateException {
       if (/* something is wrong */) {
           throw new IllegalStateException();
       }
   
       // Process as normal and return real value
   }
   
   ...
   
   int value;
   try {
       value = method();
   } catch (IllegalStateException e) {
       value = 3;
   }
