Question

我想显示我输入的输入数组。并自动打印。我想显示我输入的输入值数组。并将自动打印。

我的代码是这样的：

public class ReadArray {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.print("Input total row : ");
int row = sc.nextInt();
System.out.print("Input total column : ");
int column = sc.nextInt();

int [][] matrix = new int[row][column];
for (int i = 0; i < row; i++)
{
    for(int j = 0; j < column; j++) {
        System.out.println("Row ["+i+"]:  Column "+j+" :");
    matrix[i][j] = sc.nextInt(); 
}

}



    }

}

我想要这样的结果：

输入总行数：2 输入总列数：2

行[0]：第0列： 1

行[0]：第1列： 2

行[1]：第0列： 10

行[1]：第1列： 11

数据阵列1：1,2 数据阵列2：10,11

任何人都可以帮助我。

Answer 1

   String result="";//this variable for the last line which print the result
   for (int i = 0; i < row; i++) {
     result=result+"Data Array "+i+" :";
       for (int j = 0; j < column; j++) {
         System.out.println("Row [" + i + "]:  Column " + j + " :");
         matrix[i][j] = sc.nextInt();
         result=result+matrix[i][j]+", ";

        }

    }
System.out.println(result);////for the final result

Answer 2

for(int j = 0; j < column; j++) {
    System.out.println("Row ["+i+"]:  Column "+j+" :");
    matrix[i][j] = sc.nextInt(); //Storing input value here    
    System.out.println(matrix[i][j]);//Output the input value
}

Answer 3

代码如下

        for (int i = 0; i < baris; i++)
        {
            for(int j = 0; j < column; j++) {

    // print array data to screen
                System.out.println("Data Array "+(i+1) +matrix[i][j]);

        }
System.out.println();
}

我希望此代码对您有所帮助，请查看。

打印行和列号，然后输入matix数据和以矩阵形式打印

扫描仪扫描=新扫描仪（System.in）;

    System.out.println("Enter The Number Of Matrix Rows");

    int row = scan.nextInt();

    System.out.println("Enter The Number Of Matrix Columns");

    int col = scan.nextInt();

    //defining 2D array to hold matrix data
    int[][] matrix = new int[row][col];
    // Enter Matrix Data
    enterMatrixData(scan, matrix, row, col);

    // Print Matrix Data
    printMatrixData(matrix, row, col);

} public static void enterMatrixData（Scanner scan，int [] [] matrix，int row，int col）{

 System.out.println("Enter Matrix Data");

      for (int i = 0; i < row; i++)
      {
          for (int j = 0; j < col; j++)
          {
              matrix[i][j] = scan.nextInt();
          }
      }

}

public static void printMatrixData（int [] [] matrix，int row，int col）{

System.out.println（“你的矩阵是：”）;

    for (int i = 0; i < row; i++)
    {
        for (int j = 0; j < col; j++)
        {
            System.out.print(matrix[i][j]+"\t");
        }

        System.out.println();
    }

}
