Given a list of Strings (that contains both palindromes and nonpalindromes), write a method that returns a list of all the palindrome
strings.
TIP: Use static method references of Functional Interfaces

What I have tried:

class PalindromeExample{  
 public static void main(String args[]){  
  int r,sum=0,temp;    
  int n=454;  
  
  temp=n;    
  while(n>0){    
   r=n%10;   
   sum=(sum*10)+r;    
   n=n/10;    
  }    
  if(temp==sum)    
   System.out.println("palindrome number ");    
  else    
   System.out.println("not palindrome");    
}  
}

What is the problem ?

We are more than willing to help those that are stuck: but that doesn't mean that we are here to do it all for you! We can't do all the work, you are either getting paid for this, or it's part of your grades and it wouldn't be at all fair for us to do it all for you.

So we need you to do the work, and we will help you when you get stuck. That doesn't mean we will give you a step by step solution you can hand in!
Start by explaining where you are at the moment, and what the next step in the process is. Then tell us what you have tried to get that next step working, and what happened when you did.

Just posting your homework question and some code which pretty much ignores the whole thing isn't going to get you anywhere closer to code you can hand in.
Instead, read the question carefully, and try to implement it yourself. It's not difficult, and it gives explicit instructions you should follow.

How to solve this code?

Your code do not behave the way you expect, or you don't understand why !

There is an almost universal solution: Run your code on debugger step by step, inspect variables.
The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't know what your code is supposed to do, it don't find bugs, it just help you to by showing you what is going on. When the code don't do what is expected, you are close to a bug.
To see what your code is doing: Just set a breakpoint and see your code performing, the debugger allow you to execute lines 1 by 1 and to inspect variables as it execute.
