Question:
Now Zara has another requirement. Since there are many numbers of students, Zara would like to obtain the information of Students of a particular school. Create a java application to implement the above requirement. You are provided with the Student class that has the below attributes:
- int studId
- String studName
- String schoolName
Your are provided with getters and setters. You are also provided with a method called retrieveStudentInfo(ArrayList<Student>,String schoolName) inside TestMain class. This method should return all the student names as a ArrayList<String> who are studying in the given school.Use the given main method to test the code
CODE:–
TESTmain.java
import java.util.*;
public class TestMain{
public static ArrayList<String> retrieveStudentInfo(ArrayList<Student> al,String schoolName) {
// implement the required business logic
ArrayList<String> str=new ArrayList<String>();
for(int i=0;i<al.size();i++){
Student s=al.get(i);
if(s.getSchoolName().equalsIgnoreCase(schoolName))
{
str.add(s.getStudName());
}
}
return str;
}
public static void main(String[] args)
{
Student s1=new Student();
s1.setStudId(1);
s1.setStudName("John");
s1.setSchoolName("ZEE");
Student s2=new Student();
s2.setStudId(2);
s2.setStudName("Tom");
s2.setSchoolName("ZEE");
Student s3=new Student();
s3.setStudId(3);
s3.setStudName("Peter");
s3.setSchoolName("BEE");
Student s4=new Student();
s4.setStudId(4);
s4.setStudName("Rose");
s4.setSchoolName("OX-FO");
Student s5=new Student();
s5.setStudId(5);
s5.setStudName("Alice");
s5.setSchoolName("ZEE");
//invoke the retrieveStudentInfo method and display the result
ArrayList<Student>studentInfo=new ArrayList<Student>();
studentInfo.add(s1);
studentInfo.add(s2);
studentInfo.add(s3);
studentInfo.add(s4);
studentInfo.add(s5);
ArrayList<String>retrieveStudent=retrieveStudentInfo(studentInfo,"BEE");
for(int i=0;i<retrieveStudent.size();i++)
{
System.out.println(retrieveStudent.get(i));
}
}
}student.java
public class Student {
private int studId;
