两行三列呢？
说好的两行三列呢？怎么变成这样了?
3 回答
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.print( names[i][j] +" " );
}
//实现换行
System.out.println();
}
}
}
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] );
}
//实现换行
System.out.println();
}
}
}
就跟答案一样。
如果：
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.print( names[i][j] );
}
//实现换行
System.out.println();
}
}
}
答案就是这样了：tomjackmike
zhangsanlisiwangwu
