实现矩阵旋转90度（Java）

public class Qjc {
    public static void main(String[] args) {
        int[][] matrix=new int[][]{
   
   {3,2,8},{7,6,4},{1,5,9}};
        System.out.println("输出当前矩阵：");
        for (int i = 0; i <3 ; i++) {
            for (int j = 0; j <3 ; j++) {
                System.out.print(matrix[i][j]+"\t");
            }
            System.out.println("\n");
        }
        int[][] result=new int[matrix.length][matrix.length];
        for (int i = 0; i < result.length; i++) {
            for (int j = 0; j < result.length; j++) {
                result[i][j]=matrix[matrix.length-1-j][i];
            }
        }
        System.out.println("输出顺时针旋转90度后的矩阵：");
        for (int i = 0; i <3 ; i++) {
            for (int j = 0; j <3 ; j++) {
                System.out.print(result[i][j]+"\t");
