重写equals方法

Person 类属性：

    private String name;
    private String password;

重写后的equals方法：

@Override
    public boolean equals(Object obj) {
        // TODO Auto-generated method stub
        if (obj == this) {
            return true;
        }
        if (!(obj instanceof Person)) {
            return false;
        }
        Person person = (Person) obj;
        return this.getName().equals(person.getName())
                && this.getPassword().equals(person.getPassword());
    }

全部类代码：

public class Person {
    private String name;
    private String password;

    public Person() {
        // TODO Auto-generated constructor stub
    }

    public Person(String name, String password) {
        this.name = name;
        this.password = password;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    @Override
    public boolean equals(Object obj) {
        // TODO Auto-generated method stub
        if (obj == this) {
            return true;
        }
        if (!(obj instanceof Person)) {
            return false;
        }
        Person person = (Person) obj;
        return this.getName().equals(person.getName())
                && this.getPassword().equals(person.getPassword());
    }
}
