List Odd Numbers and Prime Numbers and Palindrome Number in Java Pro

List Odd Numbers

public class ListOddNumbers

{

public static void main(String[] args)

{

int limit = 50;

System.out.println("Printing Odd numbers between 1 and " + limit);

for(int i=1; i <= limit; i++)

{

if( i % 2 != 0)

{

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

           }

      }

   }

}

Prime Numbers

public class GeneratePrimeNumbers

{

public static void main(String[] args)

{

int limit = 100;

System.out.println("Prime numbers between 1 and " + limit);

for(int i=1; i < 100; i++)

{              

boolean isPrime = true;

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

{

if(i % j == 0)

{

isPrime = false;

break;

  }

}

if(isPrime)

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

     }

   }

}

Read Number from Console and Check if it is a Palindrome Number

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

public class InputPalindromeNumber

{

public static void main(String[] args)

{

System.out.println("Enter the number to check..");

int number = 0;

try

{      

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

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

}

catch(NumberFormatException ne)

{

System.out.println("Invalid input: " + ne);

System.exit(0);

}

catch(IOException ioe)

{

System.out.println("I/O Error: " + ioe);

System.exit(0);

}

System.out.println("Number is " + number);

int n = number;

int reversedNumber  = 0;

int temp=0;

while(n > 0)

{

temp = n % 10;

n = n / 10;

reversedNumber = reversedNumber * 10 + temp;

}

if(number == reversedNumber)

System.out.println(number + " is a palindrome number");

else

System.out.println(number + " is not a palindrome number");

   }
