关于JAVA的foreach

/** * @author Zero 2015-12-15 */public class Foreach {int time = 0;String name = "";public static void main(String[] args) {//对象Foreach f = new Foreach();Foreach[] tArr = { f, new Foreach(), new Foreach() };tArr[0].name = "你";tArr[0].time = 1;tArr[1].name = "我";tArr[1].time = 2;tArr[2].name = "他";tArr[2].time = 3;for (Foreach t : tArr) {t.name = "它";t.time = -1;t.print();}for (Foreach t : tArr) {t.print();}System.out.println();//字符串类型String[] arr = { "you", "me", "she" };for (String p : arr) {p = "he";System.out.println(p);}for (String p : arr) {System.out.println(p);}System.out.println();//整型int[] iArr = {1,2,3};for(int i : iArr ) {i = 0;System.out.println(i);}for(int i : iArr ) {System.out.println(i);}}public void print() {System.out.println(name+" , "+time);}}

运行结果：

它 , -1
它 , -1
它 , -1
它 , -1
它 , -1
它 , -1
