一道Java题，急！！！！在线等

原始数据：

A1 A2 A3 A4

B1 B2 B3 B4

C1 C2 C3 C4

转换后的数据：

A1 B1 C1

A2 B2 C2

A3 B3 C3

A4 B4 C4

public static void main(String[] args) {

List list=new ArrayList();

Object []rows1=new Object[]{"A1","A2","A3","A4"};

Object []rows2=new Object[]{"B1","B2","B3","B4"};

Object []rows3=new Object[]{"C1","C2","C3","C4"};

list.add(rows1);

list.add(rows2);

list.add(rows3);

for (int i = 0; i < list.size(); i++) {

Object []objs=(Object[])list.get(i);

for (int j = 0; j < objs.length; j++) {

System.out.print(objs[j]);

}

System.out.println();

}

在此添加代码:

}

for (int i = 0; i < 4; i++) {
for (int j = 0; j < 3; j++) {
Object []objs=(Object[])list.get(j);
System.out.print(objs[i]);

}

System.out.println();

}

添加上这段代码就可以了

这还不简单啊 你看你得到的数组都是写死得到的啊 你把得到的用一个方法得到。比如for循环啊

Object []rows1=new Object[]{"A1","A2","A3","A4"};

Object []rows2=new Object[]{"B1","B2","B3","B4"};

Object []rows3=new Object[]{"C1","C2","C3","C4"}; 就这个。
