RubyString.java

import java.util.Scanner;

public class RubyString {

   public static void main(String[] args) {
  
       String str,revstr,str2,str3;
       int strLen;
      
       Scanner kb=new Scanner(System.in);
       System.out.print("Enter a String :");
       str=kb.nextLine();
       System.out.println("You Entered String :"+str);
       strLen=str.length();
       System.out.println("The Length of the String is :"+strLen);
       revstr=revString(str);
       System.out.println("The Reverse of the String is :"+revstr);
       String arr[]=str.split(" ");
       System.out.println("The Number of Words in the String :"+arr.length);
       System.out.print("Enter another String :");
       str2=kb.nextLine();
       System.out.println("You Entered String :"+str2);
       str3=str+str2;
       System.out.println("After Concatinating the First String to Second String is :"+str3);
       System.out.println("Comparing the first String to the Second String :");
       if(str.equals(str2))
           System.out.println("First String and Second String are Equal");
       else
           System.out.println("First String and Second String are Not Equal");
      
      

   }

   private static String revString(String str) {
       String strrev="";
       for(int i=str.length()-1;i>=0;i--)
       {
           strrev+=str.charAt(i);
       }
       return strrev;
   }
