ArrayList
getter setter方法等
public class User01 {
private Integer id;
private String name;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
// 这是午无参构造 （alt+insert后点击select Note）
public User01() {
}
// 这是有参构造
public User01(Integer id, String name) {
this.id = id;
this.name = name;
}
@Override
public String toString() {
return "User{" +
"id=" + id +
", name='" + name + ''' +
'}';
}
}
运行方式
一、
import java.net.SocketOption;
public class Ideastudy02 {
public static void main(String[] args) {
System.out.println("java project");
}
}
二、
package IDEASTUDY;
public class Use02 {
public static void main(String[] args) {
System.out.println("Use02");
}
