java retain information in recursive function

Question

Is it possible to retain information via a helper function with java, without using static variables.

For example,

public void foo(){
    int v = 0;
         


        

Answer 1

A variable declared in a scope (for example method) is accessible only in this scope (e.g. not in another method).

If the information is relevant for the method only, keep the variable in the method. If the information is relevant for the whole object / class state, keep it a class member (static/non static).

For example:

public void someRecursiveMethod(int num) {
    while (num < 10) {
        num++;
        someRecursiveMethod(num);
        System.out.println("Current num = " + num);
    }
}
