Reverse the String. Finally ek chal gaya. :D

import java.io.*;
class revStr
{
public static void main(String args[])throws IOException
{
BufferedReader in=new BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter the String");
String st=in.readLine();
int l,i,p;
String b="";
st=" "+st;
l=st.length();
p=l;
for(i=l-1;i>=0;i--)
{
if(st.charAt(i)==' ')
{
b=b+st.substring(i,p);
p=i;
}
}
System.out.println(b);
}
}
