比较类成员变量的更清晰的方法

public class MyClass {
    private int id;
    private String name;

    // 构造方法、getter和setter方法省略

    @Override
    public boolean equals(Object obj) {
        if (this == obj) {
            return true;
        }
        if (obj == null || getClass() != obj.getClass()) {
            return false;
        }
        MyClass myClass = (MyClass) obj;
        return id == myClass.id && Objects.equals(name, myClass.name);
    }

    @Override
    public int hashCode() {
        return Objects.hash(id, name);
    }
}
