Need Help In My Code, Java Beginners Palindrome

that my code....pleese i need help in my while and do....

import apcslib.*;
import chn.util.*;

public class Palindrome
{
String sentence;
String reverse;

public Palindrome ()
{
sentence ="";
reverse ="";
}
public void start()
{
getInput ();
reverseInput ();
compareSens ();
}
public void getInput()
{
System.out.println("Welcome To PALINDROME");
ConsoleIO console = new ConsoleIO();
System.out.print("Please enter your sentence ");
sentence = console.readLine();
sentence = sentence.toLowerCase();
System.out.println("Your sentence is " + sentence);
}

public void reverseInput ()
{
String temp = sentence.trim();
System.out.println("Your trim sentence is "+ temp);
int senLength=temp.length();
System.out.println("Length of the sentence is "+ senLength);
int n = temp.indexOf(" ");
System.out.println("The first white space is at "+n);
while (senLength>0)
{
temp=temp=temp.substring(0,n);
temp=temp.substring(n+1,temp.length());
System.out.println("The second white space is at " + temp);
reverse=reverse+sentence.charAt(senLength-1);
senLength--;
}
System.out.println("The reverse is " + reverse);
}
public void compareSens ()
{
if (sentence.equals(reverse))
System.out.println("The sentence is a palindrome");
else
System.out.println("The sentence is not a palindrome");
}
}
