Java 在不同的行上打印二维数组

我试图打印一个有5行5列的二维数组，但是当我打印它时，我得到的却是一行[[0，0，0，0，0，0，0]，[0，0，0，0，0，0]，[0，0，0，0，0]，[0，0，0，0，0]]，如何打印它以获得5x5网格

import java.util.Arrays;

public class spil {
    public static void main(String[] args) {
        int[][] grid=new int [5][5];

        System.out.println(Arrays.deepToString(grid));
    }

    public static void print(int[][] grid) {
        for (int i = 0; i < grid.length; i++) {
            for (int j = 0; j < grid[i].length; j++) {
                System.out.print(grid[i][j]+ " ");
            }
            System.out.println();
        }
    }
}

您在第7行调用的是Arrays:：deepToString，而不是自定义打印方法

相反，使用printgrid；调用您的方法。

您可以调用您的打印方法：

public class Spil { 

   public static void main(String[]  args) {
      int[][] grid = new int[5][5]; 

      print(grid);
   } 

   public static void print(int[][] grid) {
      for (int i = 0; i < grid.length; i++) {
         for (int j = 0; j < grid[i].length; j++) {
            System.out.print(grid[i][j] + " ");
         }
         System.out.println();
      }
   }
}

检查这个

   import java.util.Arrays;

   public class spil {

    public static void main(String[] args) {

    int[][] grid=new int [5][5];
    print(grid);// you never called your function
   // System.out.println(Arrays.deepToString(grid));-----> This function was making all printing
}

public static void print(int[][] grid) {
    for (int i = 0; i < grid.length; i++) {
        for (int j = 0; j < grid[i].length; j++) {
            System.out.print(grid[i][j]+ " ");
        }
        System.out.println();
    }
}
}

打印方法有什么问题？是否尝试调用打印方法？可能是因为调用的是Arrays.deepToStringgrid而不是printgrid？

   import java.util.Arrays;

   public class spil {

    public static void main(String[] args) {

    int[][] grid=new int [5][5];
    print(grid);// you never called your function
   // System.out.println(Arrays.deepToString(grid));-----> This function was making all printing
}

public static void print(int[][] grid) {
    for (int i = 0; i < grid.length; i++) {
        for (int j = 0; j < grid[i].length; j++) {
            System.out.print(grid[i][j]+ " ");
        }
        System.out.println();
    }
}
}
