`I am writing a program for my computer science class and for whatever reason cannot get it to return the programs original menu after completing a task.

I need the program to go back to the original menu and not just stop after completing an option. Ive tried adding a while loop and a for loop to the beginning of the program but it does not fix it. Should be a simple fix but idk what it is. Thanks.

CodePudding user response：

This line if (isactive =true) you have to replace it with a loop. For example you can replace with while (isactive =true) and isactive must be initialized with true

CodePudding user response：

Since you seem to be using only the main-method, I assume you want to repeat the main-method from the beginning. In that case, you can simply call it like this:

main(null);

CodePudding user response：

Initialize isactive: boolean isactive = true;

change if to while-loop: while(isactive) instead of if(isactive =true) and modify Option 4

if (MenuOption == 4) {
                System.out.println("Thanks for checking out my program!");
                isactive=false;
            }
