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.length ; i++) {
for (int j = 0; j < names[i].length; j++) {
System.out.println( names[i][j] );
}
System.out.println();
}
}
运行结果：
tom
jack
mike
zhangsan
lisi
wangwu
这个矩阵为什么是竖着的而不是横着的

}
}
}
}这样就是横着的。
