主要对角矩阵之和JAVA

public class Main {
    public static void main(String[] args) {
        int[][] matrix1 = {{1, 0, 0}, {0, 2, 0}, {0, 0, 3}};
        int[][] matrix2 = {{4, 0, 0}, {0, 5, 0}, {0, 0, 6}};
        
        int[][] sumMatrix = new int[matrix1.length][matrix1[0].length];
        
        for (int i = 0; i < matrix1.length; i++) {
            for (int j = 0; j < matrix1[0].length; j++) {
                sumMatrix[i][j] = matrix1[i][j] + matrix2[i][j];
            }
        }
        
        // 打印结果
        for (int i = 0; i < sumMatrix.length; i++) {
            for (int j = 0; j < sumMatrix[0].length; j++) {
                System.out.print(sumMatrix[i][j] + " ");
            }
            System.out.println();
        }
    }
