Solution :-

import java.util.*;
public class Main{
    public static void main(String[] args)
    {         
         int n;
           Scanner sc = new Scanner(System.in);
           n = sc.nextInt();
           
           int count =0;
           boolean a;
           System.out.print("2 ");
           for(int i =3; n>1;i++)
           {
               a=isPrime(i);
               
               if(a)
               {
                   System.out.print(i+" ");
                   n--;
               }
           }
          
    }
    
    public static boolean isPrime(int n)
    {
        int count=0;

2) Mark's Scholarship

 

Mark studies at Teswan National University. Now is the time for exam results. Mark hopes that his scores in 5 subjects in the exam could fetch him a scholarship for his GRE preparation.
 
The following simple rules  are used to find whether he is eligible to receive the scholarship:

• The University follows 5 point grading system. In an exam, a student can receive any score from 2 to 5.  2 is called an F grade, meaning that the student has failed that exam.
• The student should not have failed any of the exams.
• The Student must obtain a full score in some of his/her exams to show that he/she is excellent in some of the subjects.
• He/She must have a grade point average not less than 4.

​You are given information regarding how Mark performed in those 5 subjects. Write a program to check whether he will receive the scholarship or not.

 
Input Format:

The input contains 5 integers denoting Mark’s 5 subjects score in the exam.

Output Format:

Output a single line - "Yes" (without quotes) if Mark will receive the scholarship, otherwise "No" (without quotes).
Refer sample input and output for formatting specifications.

Solution :-

import java.util.*;

import java.io.*;

class Main {

    public static void main(String[] args) {

    Scanner sc = new Scanner(System.in);

        System.out.println("Enter the subject 1 mark");

        int a = sc.nextInt();

        

        System.out.println("Enter the subject 2 mark");

        int b = sc.nextInt();

        

        System.out.println("Enter the subject 3 mark");

        int c = sc.nextInt();

        

        System.out.println("Enter the subject 4 mark");

        int d = sc.nextInt();

        

        System.out.println("Enter the subject 5 mark");

        int e = sc.nextInt();

        

        if(a==2 || b == 2 || c ==2 || d == 2 || e == 2)

            {

                System.out.println("No");

            }

            

        else

        {

        

        int sum = (a+b+c+d+e)/5;

        

        if(sum <= 3) 

        {

        System.out.println("No");

        }

        else 

        {

        System.out.println("Yes");

        }

        }

    }

}
