Count palindrome words in a sentence

Palindrome words remain the same after reversing also. Like “mom”–>after you reverse the word it is “mom” only.

Write a program to accept a sentence and count the number of palindrome words present in the sentence. Palindrome words are the words that remain same after reversing also. For example mom

import java.io.*;
public class PalindromeWords
{
    String str="";

    {
        BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
        System.out.println("Enter the sentence");
        str=br.readLine();
        if(str.endsWith("."))
            str=str.substring(0,str.length()-1);
        int count=0;
        int len=str.length();
        String st="";
        String arr[]=str.split("\\s+");
        int l=arr.length;
        for(int i=0;i<l;i++)
        {
            st=arr[i];

            if(palindrome(st)==true)
                count++;
        }
        System.out.println("The number of palindrome words are"+"  "  +  ""+count);
    }

    boolean palindrome(String c)
    {
        int n=c.length();
        String s="";
        for(int i=(n-1);i>=0;i--)
        {
            s+=c.charAt(i);
        }
        s=s.trim();
        if(s.equalsIgnoreCase(c))
            return true;
        else
            return false;
    }

    public static void main()throws IOException
    {
        PalindromeWords obj=new PalindromeWords();
        obj.compute();
    }
}    

Output:
Enter the sentence
