我正在尝试创建一个函数,该函数使用BasicAsteroid类型的(x,y,速度x,速度y)值制作一个随机小行星,这是创建随机小行星的构造函数和函数:
private double x, y;
private double vx, vy;
public BasicAsteroid(double x, double y, double vx, double vy) {
this.x = x;
this.x = y;
this.vx = vx;
this.vy = vy;
}
public static BasicAsteroid makeRandomAsteroid() {
Random rand = new Random();
BasicAsteroid x = new BasicAsteroid((rand.nextInt()%FRAME_WIDTH), (rand.nextInt()%FRAME_HEIGHT), (rand.nextInt()%MAX_SPEED), (rand.nextInt()%MAX_SPEED));
System.out.println(x);
return x;
}
但是,这是我创建小行星时的输出:
game1.BasicAsteroid@6773120a
game1.BasicAsteroid@4261b6b3
game1.BasicAsteroid@2673b915
game1.BasicAsteroid@113eb90b
game1.BasicAsteroid@1abcc522
如何输出值而不是class @ hashcode?
谢谢。
最佳答案
覆盖toString()
方法
@Override
public String toString(){
return "Asteroid at "+x+" "+y+" velocity "+vx+" "+vy;
}
关于java - 从HashCode Java获取值(value),我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/36012216/
