This is the first solution to to reverse each word in the given input line of strings. This program uses the built in reverse method of StringBuffer class.

import java.util.Scanner;
import java.util.StringTokenizer;

public class ReverseEachWordInSentence {

	public static void main(String[] args) {
		// TODO Auto-generated method stub

		Scanner inpLine=new Scanner(System.in);
		System.out.println("Enter an input sentence");
		String sentence=inpLine.nextLine();
		StringBuffer resultStr = new StringBuffer();
		StringTokenizer words=new StringTokenizer(sentence);

		//Process each word in a sentence, and store in an string buffer variable
		while (words.hasMoreTokens()) {
			StringBuffer nextWord=new StringBuffer(words.nextToken());
			nextWord.reverse();
			resultStr.append(nextWord+" ");
		}
		System.out.println("The sentence after reversing each word is = "+resultStr);
		inpLine.close();
	}
}
