Java中,什么是构造函数?什么是构造函数重载?

请写出以下程序输出结果:父类:package test;public class FatherClass {public FatherClass() {System.out.println("FatherClass Create");}}子类:package test;import test.FatherClass;public class ChildClass extends FatherClass {public ChildClass() {System.out.println("ChildClass Create");}public static void main(String[] args) {FatherClass fc = new FatherClass();ChildClass cc = new ChildClass();}}

从例5-2的Citizen类继承,定义一个教师Teacher类,并添加属性教师代码、教师职位和主讲课程,覆盖父类的display()方法。分别调用父类和子类的方法显示教师信息。
