Question

In a file called FourCapitalizations.java, write a program that:

• Asks the user to enter a string.
• Prints out four different versions of that string:
  1. The original version of the string.
  2. The upper-case version of the string.
  3. The lower-case version of the string.
  4. A version where the character at position 0 capitalized, and all other characters in lower case.

For example: if the user enters string "gaNDalF12 !! AB3w", your program output should look EXACTLY like this:

Please enter a string: gaNDalF12 !! AB3w
1st version: gaNDalF12 !! AB3w
2nd version: GANDALF12 !! AB3W
3rd version: gandalf12 !! ab3w
4th version: Gandalf12 !! ab3w

Answer 1

import java.util.Arrays;
import java.util.Scanner;
public class FourCapitalizations {

   public static void main (String args[])
   {
       double sum=0;
      
           Scanner sc = new Scanner (System.in);
           System.out.print("Please enter a string: ");
           String str=sc.nextLine();
           System.out.println("1st version: "+str);
           System.out.println("2nd version: "+str.toUpperCase());
           System.out.println("1st version: "+str.toLowerCase());
//captipal first character
           String cap = str.substring(0, 1).toUpperCase() + str.substring(1);
           System.out.println("1st version: "+cap);
          
          
  
   }
     
}
