Palindrome Program in Java

Palindrome number in java: A palindrome number is a number that is same after reverse. For example 545, 151, 34543, 343, 171, 48984 are the palindrome numbers.

Palindrome number algorithm

• Get the number to check for palindrome
• Hold the number in temporary variable
• Reverse the number
• Compare the temporary number with reversed number
• If both numbers are same, print "palindrome number"
• Else print "not palindrome number"

Let's see the palindrome program in java. In this java program, we will get a number variable and check whether number is palindrome or not.

class PalindromeExample{  

 public static void main(String args[]){  

 int r,sum=0,temp;    

  int n=454;//It is the number variable to be checked for palindrome  

  temp=n;    

  while(n>0){    

   r=n%10;  //getting remainder  

   sum=(sum*10)+r;    

   n=n/10;    

  }    

  if(temp==sum)    

   System.out.println("palindrome number ");    

  else    

   System.out.println("not palindrome");    

}  

} 

Output:

palindrome  number
