TY_BCS_JAVA_SLIP 7_1

Slip 7_1. Create a package series having two different classes to print the following series.

a.       Prime number

b.      Squares of numbers

Write a program to generate ‘n’ terms of the above series.

Prime.java

package Series;

public class Prime

{

                public void prime_range(int no)

                {

                                for(int i=1;i<=no;i++)

                                {

                                                int flag=0;

                                                for(int j=2;j<=i/2;j++)

                                                {

                                                                if(i%j==0)

                                                                {              flag=1;

                                                                                break;

                                                                }

                                                }

                                                if(flag==0)

                                                System.out.println(i+" ");

                                }

                }

}

Squar.java

package Series;

public class Square

{

                public void square_range(int no)

                {

                                for(int i=1;i<=no;i++)

                                {

                                                System.out.println(i+" = "+(i*i));

                                }

                }

}

import Series.Prime;

import Series.Square;

class Slip7_1

{

                public static void main(String a[]) throws IOException

                {

                                BufferedReader br =new BufferedReader(new InputStreamReader(System.in));

                                System.out.println("Enter no :");

                                int no = Integer.parseInt(br.readLine());

                                Prime p = new Prime();

                                System.out.println("Prime no upto given nos are : ");

                                p.prime_range(no);

                                Square s = new Square();

                                System.out.println("Sqaure upto given nos are : ");

                                s.square_range(no);

                }
