代码似乎运行,除了我得到的不是指定(由用户)大小的矩阵,但我认为是一个堆地址 以下是用户输入2作为大小然后输入4个数字时返回的内容:
输入矩阵大小: 2 逐行输入2乘2矩阵:2 3 4 5 行排序矩阵是...... [[D @ 3c954549BUILD SUCCESSFUL(总时间:8秒)

import java.util.Scanner;
public class Exercise7_26M {
public static void main (String[]args)
{
//Prompt user for input of matrix size
System.out.println("Enter matrix size: ");
Scanner input = new Scanner(System.in);
int size = input.nextInt();
double[][] m = new double [size][size];
//prompt user for input of array
System.out.print("Enter a " + size + " by " + size + " matrix row by row: ");
for (int row = 0; row < 2; row++)
for (int column = 0; column < 2; column++)
m[row][column] = input.nextDouble();
System.out.print("The row-sort matrix is..." + m);
}
答案 0 :(得分:0)
Java数组不会覆盖toString()
,因此您将从Object
获取默认实现。相反,您可以使用Arrays.deepToString(Object[])
之类的
System.out.println("The row-sort matrix is..." + Arrays.deepToString(m));
