java中怎么使用反射API来操作信息

class Worker{
/*两个public构造方法*/
public Worker(){
count++;
}
public Worker(String name){
super();
this.name = name;
}
/*两个private构造方法*/
private Worker(String name,int age){
super();
this.name = name;
this.age = age;
}
private Worker(int age){
super();
this.age = age;
}
/*两个private属性*/
private String name;
private int age;
/*一个public属性*/
public String parents;
/*一个private static属性*/
private static int count;
/*一个 public static属性*/
public static String address;
/*两个public方法*/
public String getName(){
return name;
}
public void setName(String name){
this.name = name;
}
/*两个private方法*/
private int getAge(){
return age;
}
private void setAge(int age){
this.age = age;
}
/*两个public static方法*/
public static void printAddress(String address){
System.out.println("printAddress==="+address);
}
public static void printAddress(){
System.out.println("printAddress===default");
}
/*两个private static方法*/
private static void printlnCount(int count){
System.out.println("printCount==="+count);
}
private static void printlnCount(){
System.out.println("printCount===000");
}
@Override
public String toString(){
return "这是一个Worker实例：name="+name+",age="+age;
}
}
