public class Car { public int fadongji; public int luntai; public int oil; public Car(){ System.out.println("父类构造方法被执行了");}}public class che extends Car{ public che(){ System.out.println("子类构造方法被执行了"); }}public class UseChe { public static void main(String[] args){ che c=new che(); c.fadongji=55; c.luntai=12; c.oil=12; }}为什么在子类父类的构造方法里面加上void 就不输出SYSO 语句了 但是去掉void 就执行了 输出语句呢??
