Java矩阵乘法生成相同的矩阵

public class MatrixMultiplication {
    public static void main(String[] args) {
        int[][] matrix1 = {{1, 2}, {3, 4}}; // 第一个矩阵
        int[][] matrix2 = {{1, 0}, {0, 1}}; // 第二个矩阵

        int[][] result = multiply(matrix1, matrix2); // 调用矩阵乘法函数

        // 打印结果
        for (int i = 0; i < result.length; i++) {
            for (int j = 0; j < result[0].length; j++) {
                System.out.print(result[i][j] + " ");
            }
            System.out.println();
        }
    }

    public static int[][] multiply(int[][] matrix1, int[][] matrix2) {
        int rows1 = matrix1.length; // 矩阵1的行数
        int cols1 = matrix1[0].length; // 矩阵1的列数
        int cols2 = matrix2[0].length; // 矩阵2的列数

        int[][] result = new int[rows1][cols2]; // 结果矩阵

        for (int i = 0; i < rows1; i++) {
            for (int j = 0; j < cols2; j++) {
                for (int k = 0; k < cols1; k++) {
                    result[i][j] += matrix1[i][k] * matrix2[k][j];
                }
            }
        }

        return result;
    }
}
