JAVA

Write a program that meets the following requirements: • Create a class for students. The class must contain each student’s name, (String), ID (int) and status (int.) The status indicates the student’s class standing: 1 for freshman, 2 for sophomore, 3 for junior and 4 for senior. • Create 20 students whose names are Name1, Name2 and so on, to Name20, and who’s IDs and status are assigned randomly. Print out the array of student objects. • Find all juniors and print their names and IDs. NOTE: Use the Math.random() method to create student ID and status.

Explanation / Answer

import java.lang.* ;
import java.util.*;

class Student
{
    private String name;
    private int id;
    private int status;
  
    public Student(String name,int id,int status)//argument constructor
    {
        this.name = name;
        this.id = id;
        this.status = status;
    }
  
    public String toString()
    {
        return "Name : "+name +" ID : "+id + " Status : "+status;
    }
    public int getStatus()// get method for status
    {
        return status;
    }
  
}

class TestStudent
{
    public static void main (String[] args)
    {
        String name;
        int id,status;
        Student[] s = new Student[20];
      
        for(int i=0;i<20;i++)
        {
            name = "name"+i;
             status= (int) Math.ceil(Math.random() * 4);//random number between 1 and 4
             id = (int) Math.floor(Math.random() * 101+1);//random number between 1 and 100
          
            s[i] = new Student(name,id,status);
        }
  
         for(int i=0;i<20;i++)
        {
           if(s[i].getStatus() == 3)
            System.out.println(s[i].toString()+" ");
      
        }
    }
}
