public class Person {
private String name;
private int age;
public Person() {
}
public Person(String name, int age) {
this.name = name;
this.age = age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public boolean equals(Object obj) {
if (this == obj) {
return true;
}
if (!(obj instanceof Person)) {
return false;
}
Person p = (Person) obj;
return this.name.equals(p.name) && this.age == p.age;
}
这是一个person类我重写了equals方法了大事还是保证不了唯一性啊。
