如何JAVA对象实例化

package com.zhidao.demo;

public class Bird {
private int leg;
private int wing;

public Bird() {
super();
}
public Bird(int leg, int wing) {
super();
this.leg = leg;
this.wing = wing;
}

public int getLeg() {
return leg;
}

public void setLeg(int leg) {
this.leg = leg;
}

public int getWing() {
return wing;
}

public void setWing(int wing) {
this.wing = wing;
}

public static void main(String[] args) {
Bird b1 = new Bird(3,2);
Bird b2 = new Bird(4,0);
System.out.println(b1.getLeg()+"::"+b1.getWing());
System.out.println(b2.getLeg()+"::"+b2.getWing());
}

}

把你Bird构造方法Bird()中的内容
复制到main方法system.out.println前面去即可。

在main方法中做，另外，大括号好像不匹配
