Program On Palindrome And Prime Number

Write a program to accept the lower range and upper range from the user and display the Prime Palindrome number in that range.

Methods used boolean isPrime()

boolean isPalindrome()

void generate() and main()

  import java.io.*;

  class PalPrime

  {

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

   int i,lower,upper;

   public void generate() throws Exception

   {

     System.out.println("Enter the lower range:");

     lower=Integer.parseInt(br.readLine());

     System.out.println("Enter the upper range:");

     upper=Integer.parseInt(br.readLine());

System.out.print(" The Prime Palindrome numbers are:");

     for(i=lower;i<=upper;i++)

     {

      if(isPrime(i) && isPalindrome(i))

       System.out.print(i+ " ");

       }

     

       }

     private boolean isPrime(int n)

{

 for(i=2;i< n;i++)

{

 if(n%i==0)

break;

}

if(i==n)

return true;

else

return false;

}

 private boolean isPalindrome(int n)

{

int rev=0;

for(i=n;i>0;i=i/10)

{

 rev=rev*10+i%10;

}

if(rev==n)

return true;

else

return false;

}

       public static void main(String args[])throws Exception

       {

        PalPrime ob=new PalPrime();

        ob.generate();

        }

        }
