DataInputStream dis=new DataInputStream(System.in);

System.out.println("enter any string ");

str=dis.readLine();

}

catch(Exception e)

{

System.out.println(e);

}

StringBuffer s=new StringBuffer(str);

System.out.println(""+s.reverse());//prints reverse string

String s1="How are you?";

String ss[]=s1.split(" ");

StringBuffer[] sb=new StringBuffer[ss.length];

for(int i=0;i<ss.length;i++)

{

sb[i]=new StringBuffer(ss[i]);

System.out.print(sb[i].reverse()+" ");
