问个问题！！！ 为什么我输出的是散列值？？源代码 public class App { public static void main(String[] args) { Point start=new Point(1); Point end= new Point(2,3); Line l=new Line(1,2,3,4); System.out.println(l.toString()); } } public class Line { private Point start; private Point end; public Line(Point start,Point end){ super(); this.start=start; this.end=end; } public Line(int startX, int startY, int endX, int endY) { start = new Point(startX, startY); end = new Point(endX, endY); } @Override public String toString() { return "Line [" + (start != null ? "start=" + start + ", " : "") + (end != null ? "end=" + end : "") + "]"; } } public class Point { private int x; private int y; public Point(){ this.x=0; this.y=0; } public Point(int x){ this(x,x); } public Point(int x,int y){ this.x=x; this.y=y; } } 该怎么解决
