java中for循环遍历的常见用法

1、遍历数组

public class forsumary {
    public static void main(String[] args) {
        int[] intarry={1,2,3,4,5};
        for (int i = 0; i 

或：

public class forsumary {
    public static void main(String[] args) {
       int[] intarry={1,2,3,4,5,6};
        for (int s:intarry) {
            System.out.println(s);
        }
}
}

2、遍历集合

import java.util.ArrayList;
import java.util.List;
public class forsumary {
    public static void main(String[] args) {
        List list=new ArrayList<>();
        list.add("zhangsan");
        list.add("lisi");
        list.add("wangwu");
        list.add("mazi");
        for (int i = 0; i
