Question

我输入网络摄像头视频处理列表中的每个帧1乘8坐标值。

值如下：

points=[33,12,3,2,54,222,44,54] 
points=[54,32,1,1,33,44,54,21] 
points=[64,443,2,2,2,44,3,5]

这是我的代码：

public class Sample {
    private List<List<Integer>> matrix; //Getter and Setter Method 

    public List<List<Integer>> getMatrix() {
        return matrix;
    }

    public Sample setMatrix(List<<Integer>> matrix) {
        this.matrix = matrix;
        return this; 
    }

    public void list_method(List<Integer> points) { 

        Sample sample = new Sample(); //Class object

        sample.getMatrix().add();

        System.out.println(sample);
    }
}

我的结果如

matrix = [33,12,3,2,54,222,44,54]
matrix = [33,12,3,2,54,222,44,54 ,54,32,1,1,33,44,54,21] 
matrix =[33,12,3,2,54,222,44,54 ,54,32,1,1,33,44,54,21,64,443,2,2,2,44,3,5  ]

但我希望它的形式如下：

matrix = [33,12,3,2,54,222,44,54]
matrix = [33,12,3,2,54,222,44,54], [54,32,1,1,33,44,54,21]
matrix = [33,12,3,2,54,222,44,54], [54,32,1,1,33,44,54,21], [64,443,2,2,2,44,3,5]

Answer 1

在list_method中，您只需要撰写matrix.add(points);

我不知道这是否是拼写错误，但public Sample setMatrix(List<<Integer>> matrix) {应为public Sample setMatrix(List<List<Integer>> matrix) {
