编java程序求解n阶魔方矩阵代码

Answer 1

import java.util.Scanner;

public class Matrix {

public static void main(String[] args) {
// TODO Auto-generated method stub

System.out.println("请输入n*n数组，n=");
Scanner sc = new Scanner(System.in);
int n = sc.nextInt();
int[][] a = new int[n][n];//定义n*n数组
int result = 0;
for(int i=0; i<n; i++){
for(int j=0; j<n; j++){
System.out.println("请输入第"+i+"行，第"+j+"列元素：");
a[i][j]=sc.nextInt();
}
result +=a[i][i];
}
System.out.println("对角线元素和为:"+result);
}

}
