Question

Write a Java class that takes a full name (first and last) as inputted by the user, and outputs the initials. Call the class Initials.

For example, if the name is Jane Doe, the initials outputted will be J and D, and the output should be as follows: J D.

Use of the java.util.Scanner class must be included in this assignment. Note: This class allows the user to provide input to your program after it has begun to run i.e. the input is not provided to the String [] args parameter of your program's main() method, when you first invoke the java command to run it.

Try to include the Scanner method nextline().

Try to include the String method String substring(int beginIndex, int endIndex).

Also try to include the String method int indexOf(String str).

Explanation / Answer

import java.util.Scanner;

class OutputInitial{
   public static void main(String[] args) {
       Scanner sc = new Scanner(System.in);
       String name;
       System.out.print("Enter full name: ");
       name = sc.nextLine(); // reading full name
       sc.close();
       int index = name.indexOf(' '); // finding index of space
       String firstName = name.substring(0, index);//getting first name from name
       String lastName = name.substring(index+1, name.length()); //getting last name
       System.out.println(firstName.charAt(0)+" "+lastName.charAt(0));//printing first character of

//firstname nad lastname
   }
}

/*

OUTPUT:

Enter full name: Jane Doe
J D
