Is there any way of executing the already executed code in java

Is there any way of executing the already executed code in java.

for example in the main method i have int variable a = 10; and later point in time say suppose at the end of execution i will check some conditions on its(a's) value and if the condition fails then i want it to execute from the beginning.

there may be some other scenarios also, right now i have this.

Edit: without looping and methods. which i know. like goto statements in c++. and dont think only for the above stated example there might be some other example which might need the way i wanted.

The correct answer is: No, there is no way to do that in Java. You would have to use a loop or recursive method.

why can't you just do something like this?

   do {
       a = processSomething();
   } while(a != 10);

EDIT: if you can't use a proper loop construct, then recursion is your only real choice.. something like this:

int rFunction(int a) {
    // if we found our needed value, return it
    if(a == 10) {
        return a;
    }

    a = whatever();

    rFunction(a); // call again with new value   
}

Put it in a function, or create a loop.
