将模糊数组转化成完整数组

public class ReCoverSparseArray {
    public static void main(String[] args) {
        //定义一个模糊数组
        int[][] arr1 = new int[][]{{11,11,3},{1,2,1},{2,3,2},{3,1,1}};

        System.out.println("-------------模糊数组------------");
        for (int i = 0; i < arr1.length; i++) {
            for (int j = 0; j < arr1[i].length; j++) {
                System.out.print(arr1[i][j] + "  ");
            }
            System.out.println();
        }

        //根据模糊数组的数据定义一个完整数组
       int[][] arr2 = new int[arr1[0][0]][arr1[0][1]];

        //初始化完整数组
        for (int i = 0; i < arr2.length; i++) {
            for (int j = 0; j < arr2.length; j++) {
                arr2[i][j] = 0;
            }
        }
        //根据模糊数组为完整数组赋值
        for (int i = 1; i < arr1.length; i++) {
            for (int j = 0; j == 0; j++) {
                arr2[arr1[i][j++]][arr1[i][j++]] = arr1[i][j];
            }
        }

        System.out.println("-------------完整数组------------");
        for (int i = 0; i < arr2.length; i++) {
            for (int j = 0; j < arr2.length; j++) {
                System.out.print(arr2[i][j] + "  ");
            }
            System.out.println();
        }

     }
}
