本文通过三个Java类的实例化及属性设置演示了如何使用构造方法初始化对象，并展示了如何通过公共方法来获取和设置类的私有属性。

class Employee{
int number;
String name;
int xinshui;
int zengzhang;
public void tell(){
  System.out.println("编号："+number+",姓名："+name+",薪水："+xinshui+"，增长："+zengzhang+",工资："+(zengzhang+xinshui));
}
}
public class dier{
public static void main(String args[]){
  Employee per=new Employee();
  per.number=140201128;
  per.name="辽宁";
  per.xinshui=3000;
  per.zengzhang=1000;
  per.tell();
}
}

class Dog{
private String name;
private String color;
private int age;
public Dog(String name,String color,int age){
  this.setName(name);
  this.setColor(color);
  this.setAge(age);
}
public void tell(){
  System.out.println("名字："+name+",颜色："+color+",年龄："+age);
}
public String getName(){
  return name;
}
public void setName(String a){
  name=a;
}
public String getColor(){
  return color;
}
public void setColor(String b){
  color=b;
}
public int getAge(){
  return age;
}
public void setAge(int c){
  age=c;
}
}
public class disi{
public static void main(String args[]){
  Dog per=new Dog("大黄","黄",3);
  per.tell();
}
}

class User{
private String name;
private String cdk;
private int num;
public User(){}
public User(String name){
  this.setName(name);
}
public User(String name,String cdk){
  this.setName(name);
  this.setCdk(cdk);
}
public void tell(){
  System.out.println("名字："+name+",口令："+cdk+",个数："+num);
}
public String getName(){
  return name;
}
public void setName(String a){
  name=a;
}
public String getCdk(){
  return cdk;
}
public void setCdk(String b){
  cdk=b;
}
public int getNum(){
  return num;
}
public void setNum(int c){
  num=c;
}
}
public class diwu{
public static void main(String args[]){
  User per=new User("LinXinHua","lxh",3);
  per.tell();
}
}

class Address{
String country;
String shengfen;
String city;
String jiedao;
int youbian;
public void tell(){
  System.out.println("国家："+country+",省份："+shengfen+",城市："+city+"，街道："+jiedao+"，邮编："+youbian);

}
public class diyi{
public static void main(String args[]){
  Address per=new Address();
  per.country="中国";
  per.shengfen="辽宁";
  per.city="沈阳";
  per.jiedao="沈北新区";
  per.youbian=11300;
  per.tell();
}
}
