java - for 循环15

package com.demo.test;

public class circulate {
    public static void main(String[] args) {
        System.out.println();
        f();
    }
    public static void f() {
        for (int i=0 ;i<4;i++){
            System.out.println("我跑！");
        }
    }
}

package com.demo.test;

public class circulate {
    public static void main(String[] args) {
        System.out.println();
        f(9);
    }

    public static void f(int q) {
        for (int i = 0; i < q; i++) {
            System.out.println("我跑！"+i);
        }
    }
}

　　和js的for循环没啥区别的，依旧两个案例
