if i will give input as a

hi how are you

o/p would be --

 ih woh era uoy

well, split the string of words by space first, then you can loop through it and reverse the words in each loop.
You can use the string methods like

split()

and

reverse()

i got it thanks for your help everyone

import java.util.Scanner;
public class SentenceReverse
{
public static void main(String[] args)
{
Scanner scn = new Scanner(System.in);
System.out.println("Enter a string:");
String s = scn.nextLine();
String s1 ="";
String [] arr = s.split(" ");
for(int i=0;i<arr.length;i++)
{
s1 += new StringBuffer(arr[i]).reverse().toString() + " ";
}
System.out.println(s1);
}
}
