2. 类User:
package domain;
public class User {
private int id;
private String name;
public User() {}
public User(String name) { this(0, name); }
public User(int id, String name) {
this.id = id;
this.name = name;
}
public int getId() { return id; }
public void setId(int id) { this.id = id; }
public String getName() { return name; }
public void setName(String name) { this.name = name; }
@Override
public String toString() { return "ID: " + id + ", Name: " + name; }
}
