In this approach we are using split() method to reverse the words of a string.
import java.util.*;
public class ReverseWords {
public static void main(String args[] ) {
Scanner sc=new Scanner(System.in);
System.out.println(“Enter a String”);
String str=sc.nextLine();
String[ ] words= str.trim().split(“\\s+”);
StringBuilder reverseString= new StringBuilder();
for(int i=words.length-1;i>=0;i–) {
reverseString.append(words[i]);
//Add a space between words
if(i>0) {
reverseString.append(” “);
}
}
System.out.println(“Reversed string is :”+reverseString.toString());
}
}
