这里是新程序员,对于我认为递归的一些代码存在一些问题.

public static int sum (int a) {
    int input = goodInput(); //get input from below method without having to put its code in this one
    if (input==-1)//so user has the ability to exit at any time
        return a; //when user has finally entered -1, the final sum is sent out
    else; //for scenarios before last input 
    int b = a + input; //adding the newest input to the sum 
    int c = sum(b); //throw the total into the method …
