java类数组与JSON的相互转换

废话不多说，直接上代码：

准备测试类：

public class Point {

    private double x;
    private double y;

    public Point() {
        x = Math.random();
        y = Math.random();
    }

    public double getX() {
        return x;
    }

    public void setX(double x) {
        this.x = x;
    }

    public double getY() {
        return y;
    }

    public void setY(double y) {
        this.y = y;
    }
}

Java类数组与json的相互转化：

    public static void main(String[] args) {

        Point[] test = new Point[3];
        for (int i = 0; i < test.length; i++) {
            test[i] = new Point();
        }

        String va = JSON.toJSonString(test);
        System.out.println(va);

//        Point[] ta = (Point[]) (JSON.parseArray(va, Point.class)).toArray();  // 编译通过，运行不灵
        List tempa = JSON.parseArray(va, Point.class);
        Point[] ta = tempa.toArray(new Point[0]);  // 编译通过，运行不灵
        for (int i = 0; i < ta.length; i++) {
            System.out.println(JSON.toJSonString(ta[i]));
        }
    }
