使用this的聲明方法

class Person{
private String name;
private int age;
public Person(String name,int age){
this.setName(name);
this.setAge(age);
}
public boolean compare(Person per){
Person p1 = this;
Person p2 = per;
if(p1 == p2){
return true;
}
if(p1.name.equals(p2.name)&&p1.age==p2.age){
return true;
}else{
return false;
}
}
public String getName(){
return name;
}
public void setName(String n){
name = n;
}
public int getAge(){
return age;
}
public void setAge(int a){
age = a;
}
}




public class Demo01 {
public static void main(String args[]){
Person per1 = new Person("張三",30);
Person per2 = new Person("張三",30);
if(per1.compare(per2)){
System.out.println("兩個參數相等");
}else{
System.out.println("兩個參數不相等");
}
}

}

仔細看看，你會有所收穫的
