public class Arrays {
public static void main(String[] args) {
// TODO Auto-generated method stub
int arrays[][] = {
{3,4,6,8,6,8},
{5,3,4,9,9,4},
};
for (int i = 0; i< arrays.length;i++){
for (int j =0; j<arrays[i].length; j++){
int i1 = (int)(Math.random()*arrays.length);
int j1 = (int)(Math.random()*arrays[i].length);
int temp = arrays[i][j];
arrays[i][j] = arrays[i1][j1];
arrays[i1][j1] = temp;
}
}
System.out.println(arrays);
}
}
为什么不能打乱顺序？
