while(true) loop only executes once

Question

I wrote a piece of code which should be executed until the condition is satisfied. I have 2 classes using the same structure. In one of them while (true) loop executes as expected; in the other class the program exits the loop after the first recursion.

        protected static boolean flag = true;
        private static int value=0;
        private static int limit=10;
        .
        .
        .

        public static int method(){

            if (limit-value <=0)
            {

            ...
            }

            else {
            while(flag) {
                if (limit-value > 0 ) {

                    *the action I want to perform until the condition is satisfied*

                    value++; 

                }

                else if (limit==value)
                {
                    flag = false;
                } 
                return int_Value;
            }

        }
    }
    return int_Value;
}

I expect the while(true) loop to be executed until the condition is satisfied (which is more than once).

Answer 1

通过一些清理缩进，很明显 while 循环包含一个无条件return 。

Answer 2

if you look at your code the while loop goes like this

 while(flag) {
    if (limit-value > 0 ) {

        *the action I want to perform until the condition is satisfied*

             value++; 

    }

    else if (limit==value)
    {
            flag = false;
    } 
    return int_Value;
}

after executing either if or if else statement there is a return int_value statement which is causing the problem

Answer 3

Although I did debugging I couldn't see it in the first place. I performed another debug session after @user3437460 's suggestion, so I was able to find out:

It seems like an additional return statement was used!(return int_Value;), the one after else if block. So, the program returns a value and never goes back into the loop. After deleting the first return statement, program runs just fine.
