Question

我使用了多维来创建一个表格，但是当我运行它时，表格似乎水平移动，如何在运行时使其垂直排列？

public static void main(String args[]){
    int firstarray[][]={{1,2,3,4,5}
                        ,{6,7,8,9,10}};
    int secondarray[][]={{30,31,32,33,}
                        ,{43},{4,5,6}};

    System.out.println("This is the first array");
    display(firstarray);

    System.out.println("This is the second array");
    display(secondarray);
}
public static void display (int x[][]){
    for(int row=0;row<x.length;row++){
        for(int column=0;column<x[row].length;column++){
            System.out.print(x[row][column]+"\t");
        }
    }   
  }
}

Answer 1

在内循环后断开每一行：

for (int row=0; row<x.length; row++) {
   for (int column=0; column<x[row].length; column++) {
      System.out.print(x[row][column]+"\t");
   }
   System.out.println(); // Break current line
}

Answer 2

Inner Loop打印出为您生成每一行的每一列，因此在每行的末尾您必须使用System.out.println转到与外循环相关的下一行。在更好的场景中，如果你想要新行，在阅读下一行的新列之前，你必须使用System.out.println`

希望此示例可以帮助您更好地学习

代码：

       int a[][] = {{1, 2, 3, 4, 5}, {6, 7, 8, 9, 10}};

        for (int i = 0; i < a.length; i++) {
            System.out.print("---> It is going to read colmuns in order to make a line");
            for (int j = 0; j < a[0].length; j++) {
                System.out.print(a[i][j]+" ");
            }
            System.out.println("-->It is going to make a new next line");
        }

输出：

---> It is going to read colmuns in order to make a line 1 2 3 4 5 -->It is going to make a new next line
---> It is going to read colmuns in order to make a line 6 7 8 9 10 -->It is going to make a new next line
