能输出正确结果，但是后面还有一行什么东西看不懂……
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 2
at HelloWorld.main(HelloWorld.java:8)
代码是这样的：
public class HelloWorld {
public static void main(String[] args) {
// 定义两行三列的二维数组并赋值
String[][] names={{"tom","jack","mike"},{"zhangsan","lisi","wangwu"}};
// 通过二重循环输出二维数组中元素的值
for (int i = 0; i <names[i].length; i++) {
for (int j = 0; j < names[i].length; j++) {
System.out.println(names[i][j]);
}
System.out.println();
}
}
}
