/** * 遍历数组的两种方式 *  * @author supermanxkq *  */public class Test5 {	public static void main(String[] args) {		String[] name = new String[] { "张三", "李四", "王五", "赵六" };		for (int i = 0; i < name.length; i++) {			System.out.println(name[i]);		}						System.out.println("使用while循环。。。。。。。。。。");		int index = 0;		while (index < name.length) {			System.out.println(name[index++]);		}	}}

后者效率要比前者的效率高!
