TextRecursion

public class TextRecursion {
    public static void main(String[] args) {
        int result=recursion(10);
        System.out.println(result);
    }
    public static int recursion(int n){
        if(n==1){
            return 1;
        }else {
            return n*recursion(n-1);
        }
    }
}
To text the way of recursion,so I write this code.The key point of the code is the use of the variable n,the key of the recursion's calling yourself.
