我需要朝着正确的方向努力。到目前为止我有这个编码>>
import java.util.Scanner;
class clubmember {
public static void main(String[] args) {
int id;
String fname, lname;
Scanner input = new Scanner(System.in);
System.out.println("ID>");
id = input.nextInt();
System.out.println("Fname >");
fname = input.next();
System.out.println("lname >");
lname = input.next();
Person object1 = new Person(id, fname, lname);
System.out.println(object1);
}
}
public class Person {
private final int id;
private final String firstName;
private final String lastName;
public Person(int id, String firstName, String lastName) {
this.id = id;
this.firstName = firstName;
this.lastName = lastName;
}
public int getId() {
return id;
}
public String getFirstName() {
return firstName;
}
public String getLastName() {
return lastName;
}
@Override
public String toString() {
return String.valueOf(id) + ": " + firstName + " " + lastName;
}
}
我需要创建一个显示名称成员ID的二叉树。我已经看过无穷无尽的二叉树,但却混淆了他们如何抓住这些信息然后继续它。任何人都可以给我一个起点或一些与此相似的示例代码吗?
