使用"ORZ"這符號，那就在文字敘述打上 空白+冒號+英文字大寫。
[Example] _ : ORZ 顯示如以下整排，雖然實用性不大但是真的很可愛，拜託支持囉。
題目：
說明：
import java.util.Scanner;
import java.util.Random;
public class RandomArray{
public static void main(String[] args){
Scanner scanner = new Scanner(System.in);
System.out.println("Input Rows ans Cols:");
int m = scanner.nextInt();
int n = scanner.nextInt();
boolean play = false;
while(play != true){
Matrix a = new Matrix(m, n);
a.setMatrix();
a.getMatrix();
play = a.check();
}
}
}
class Matrix{
private int value;
private int rows;
private int cols;
private int[][] storage;
Random random = new Random();
public Matrix(){
}
public Matrix(int rows, int cols){
this.rows = rows;
this.cols = cols;
storage = new int[rows][cols];
}
public void randomValue(){
value = random.nextInt(2);
}
public void setMatrix(){
for(int i = 0; i < rows; i++){
for(int j = 0; j < cols; j++){
randomValue();
storage[i][j] = value;
}
}
}
public void getMatrix(){
for(int i = 0; i < rows; i++){
for(int j = 0; j < cols; j++){
System.out.print(storage[i][j] + " ");
}
System.out.println();
}
}
public boolean check(){
int rowsum = 0;
int colsum = 0;
for(int i = 0; i < rows; i++){
for(int j = 0; j < cols; j++){
rowsum += storage[i][j];
}
if(rowsum != 3){
return false;
}
rowsum = 0;
}
for(int i = 0; i < cols; i++){
for(int j = 0; j < rows; j++){
colsum += storage[j][i];
}
if(colsum != 2){
return false;
}
colsum = 0;
}
return true;
}
}
