Create 3 java variables an intage a doublegpa and a Stringho

Create 3 java variables, an int(age), a double(gpa), and a String(homeTown).

Ask the user to input his or her home town and do the following with the home town:

Print a message welcoming the person from their home town.

Capitalize (upperCase()) all letters in the home town and print it again. hint: ( upperTown = homeTown.toUpperCase(); )

print out the number of letters in the home town. hint: (int len=homeTown.length();)

Solution

package myProject;
import java.util.*;
public class StringOperation
{
   public static void main(String ss[])
   {
       //Scanner class object created
       Scanner sc = new Scanner(System.in);
       //Accepts age
       System.out.println(\"Enter the age: \");
       int age = sc.nextInt();
       //Accepts gpa
       System.out.println(\"Enter the gpa: \");
       double gpa = sc.nextDouble();
       //Clear console
       sc.nextLine();
       //Enter home town
       System.out.println(\"Enter the home town: \");
       String homeTown = sc.nextLine();
       //Welcome message
       System.out.println(\"Welcome to your home town: \" + homeTown);
       //Converts to upper case
       String upperTown = homeTown.toUpperCase();
       System.out.println(\"Your home town: \" + upperTown);
       //Counts the number of characters in home town
       System.out.println(\"Number of letters in your home town: \" + homeTown.length());
   }
}

Output

Enter the age:
12
Enter the gpa:
56.2
Enter the home town:
Berhampur
Welcome to your home town: Berhampur
Your home town: BERHAMPUR
Number of letters in your home town: 9
