二维数组双重循环中外层的name.length和name[j].length?
public class HelloWorld {
public static void main(String[] args) {
// 定义两行三列的二维数组并赋值
Strings [][] 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.length ; i++) {
for (int j = 0; j < names[i].length; j++) {
System.out.println( names[i] [j] );
}
System.out.println();
}
}
}
name.length和name[j].length搞不懂啊~~
