输入两个m行n列的矩阵对象，输出两个矩阵的和以及第一个矩阵的转置矩阵java

可以通过以下Java代码实现输入两个m行n列的矩阵对象，输出两个矩阵的和以及第一个矩阵的转置矩阵：

import java.util.Scanner;

public class MatrixAdditionAndTranspose {
   public static void main(String[] args) {
      Scanner input = new Scanner(System.in);
      int m, n, i, j;
      
      // 输入第一个矩阵
      System.out.print("Enter the number of rows and columns of the first matrix: ");
      m = input.nextInt();
      n = input.nextInt();
      int[][] matrix1 = new int[m][n];
      System.out.println("Enter the first matrix: ");
      for (i = 0; i < m; i++) {
         for (j = 0; j < n; j++) {
            matrix1[i][j] = input.nextInt();
         }
      }
      
      // 输入第二个矩阵
      System.out.print("Enter the number of rows and columns of the second matrix: ");
      m = input.nextInt();
      n = input.nextInt();
      int[][] matrix2 = new int[m][n];
      System.out.println("Enter the second matrix: ");
      for (i = 0; i < m; i++) {
         for (j = 0; j < n; j++) {
            matrix2[i][j] = input.nextInt();
         }
      }
      
      // 输出两个矩阵的和
      System.out.println("The sum of the matrices is: ");
      for (i = 0; i < matrix1.length; i++) {
         for (j = 0; j < matrix1[i].length; j++) {
            System.out.print(matrix1[i][j] + matrix2[i][j] + " ");
         }
         System.out.println();
      }
      
      // 输出第一个矩阵的转置矩阵
      System.out.println("The transpose of the first matrix is: ");
      for (i = 0; i < matrix1.length; i++) {
         for (j = 0; j < matrix1.length; j++) {
            System.out.print(matrix1[j][i] + " ");
         }
         System.out.println();
      }
   }
}
