一案例要求：

二具體代碼(需要在同一個包下創建三個類)

Ⅰ：實現類

package 重修;import java.util.Random;
import java.util.Scanner;public class first {public static void main(String[] args) {javabean[]movies=new javabean[4];movies[0]= new javabean("水門橋", 23.5,123,1);movies[1]= new javabean("西游記", 23.5,123,2);movies[2]= new javabean("星游記", 23.5,123,3);movies[3]= new javabean("活著", 23.5,123,4);javabeanoperate s=new javabeanoperate(movies);s.show();Scanner sc=new Scanner(System.in);int x;System.out.print("請輸入要查詢的編號:");x= sc.nextInt();System.out.println();s.search(x);}
}

Ⅱ實體類：

package 重修;public class javabean {private String name;private double price;private double score;private int id;public javabean() {}public javabean(String name, double price, double score, int id) {this.name = name;this.price = price;this.score = score;this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public double getPrice() {return price;}public void setPrice(double price) {this.price = price;}public double getScore() {return score;}public void setScore(double score) {this.score = score;}public int getId() {return id;}public void setId(int id) {this.id = id;}
}

Ⅲ操作類：

package 重修;public class javabeanoperate {private javabean[] javabeans;public  javabeanoperate(javabean[] movies) {this.javabeans = movies;}public void show(){System.out.println("-------全部電影信息如下-------");for (int i = 0; i < javabeans.length; i++) {javabean m = javabeans[i];System.out.println("姓名" + m.getName() + " 價格 " + m.getPrice() + " 評分 " + m.getScore() + "編號 " + m.getId());System.out.println("-----------------------");}}public void search(int id){for (int i = 0; i < javabeans.length; i++) {javabean m = javabeans[i];if(m.getId()==id){System.out.println("找到了");System.out.println("姓名" + m.getName() + " 價格 " + m.getPrice() + " 評分 " + m.getScore() + "編號 " + m.getId());return ;}}System.out.println("未查到該編號相關信息");}
}

三運行結果：
