Java两个矩阵相加生成c矩阵，对c矩阵元素查询，输出行和列

好的，下面是Java代码实现：

import java.util.Scanner;

public class MatrixAddition {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);

        // 输入第一个矩阵的行数和列数
        System.out.print("Enter the number of rows and columns of the first matrix: ");
        int m1 = input.nextInt();
        int n1 = input.nextInt();

        // 创建第一个矩阵
        int[][] matrix1 = new int[m1][n1];
        System.out.println("Enter the first matrix:");
        for (int i = 0; i < m1; i++) {
            for (int j = 0; j < n1; j++) {
                matrix1[i][j] = input.nextInt();
            }
        }

        // 输入第二个矩阵的行数和列数
        System.out.print("Enter the number of rows and columns of the second matrix: ");
        int m2 = input.nextInt();
        int n2 = input.nextInt();

        // 创建第二个矩阵
        int[][] matrix2 = new int[m2][n2];
        System.out.println("Enter the second matrix:");
        for (int i = 0; i < m2; i++) {
            for (int j = 0; j < n2; j++) {
                matrix2[i][j] = input.nextInt();
            }
        }

        // 检查两个矩阵是否可以相加
        if (m1 != m2 || n1 != n2) {
            System.out.println("The matrices cannot be added.");
        } else {
            // 创建结果矩阵
            int[][] resultMatrix = new int[m1][n1];

            // 将两个矩阵相加得到结果矩阵
            for (int i = 0; i < m1; i++) {
                for (int j = 0; j < n1; j++) {
                    resultMatrix[i][j] = matrix1[i][j] + matrix2[i][j];
                }
            }

            // 输出结果矩阵
            System.out.println("The result matrix is:");
            for (int i = 0; i < m1; i++) {
                for (int j = 0; j < n1; j++) {
                    System.out.print(resultMatrix[i][j] + " ");
                }
                System.out.println();
            }

            // 查询元素并输出行和列
            System.out.print("Enter an element to search for: ");
            int element = input.nextInt();
            boolean found = false;
            for (int i = 0; i < m1; i++) {
                for (int j = 0; j < n1; j++) {
                    if (resultMatrix[i][j] == element) {
                        System.out.println("The element " + element + " is at (" + i + ", " + j + ")");
                        found = true;
                    }
                }
            }
            if (!found) {
                System.out.println("The element " + element + " is not in the matrix.");
            }
        }

        input.close();
    }
}

这段代码实现了两个矩阵的相加，并且可以查询结果矩阵中某个元素所在的行和列。注意，这里假设输入的两个矩阵都是整数矩阵。
