[31] ArrayList 활용 문제

 

 

Book  클래스 

package arrayTest2;

public class Book {
	
	private String name;
	private String author;
	
	public Book(String name ,String author) {
		this.name = name;
		this.author = author;
	}

	public String getName() {
		return name;
	}

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

	public String getAuthor() {
		return author;
	}

	public void setAuthor(String author) {
		this.author = author;
	}
	
	
	
}

 

 

Student 클래스 

addBook() 메소드 

showInfo() 메소드

 

package arrayTest2;

import java.util.ArrayList;

public class Student {
	
	private String name;
	private int StudentID;
	ArrayList<Book> bookList;
	
	
	public Student(String name , int StudentID) {
		this.name = name;
		this.StudentID = StudentID;
		bookList = new ArrayList<Book>();
	}
	public void addBook(String name , String author) {
		Book book = new Book(name, author);
		bookList.add(book);
	}
	public void showInfo() {
		// 앞부분 학생 한번만 출력 	
		System.out.print(name +"학생이 읽은 책은 : ");  // 앞부분 학생 한번만 출력 	
		for(Book book : bookList) {
			System.out.print(book.getName() + " ");
		}
		System.out.println(""); // 한명이 읽은책 다 출력후 그다음 학생으로 
	}
}

 

StudentTest 클래스 

각 학생마다 addBook 책을 추가 한다. 

 

package arrayTest2;

public class StudentTest {
	public static void main(String[] args) {
		Student studentLee = new Student("Lee",10000);
		Student studentKim = new Student("Kim",20000);
		Student studentCho = new Student("Cho",30000);
		
		studentLee.addBook("태백산맥1", "조정래");
		studentLee.addBook("태백산맥2", "조정래");
		
		studentKim.addBook("토지1", "박경리");
		studentKim.addBook("토지2", "박경리");
		studentKim.addBook("토지3", "박경리");
		
		studentCho.addBook("해리포터1", "롤링");
		studentCho.addBook("해리포터2", "롤링");
		studentCho.addBook("해리포터3", "롤링");
		studentCho.addBook("해리포터4", "롤링");
		studentCho.addBook("해리포터5", "롤링");
		studentCho.addBook("해리포터6", "롤링");
	
		studentLee.showInfo();
		studentKim.showInfo();
		studentCho.showInfo();
	}
}
