Question

*MYST BE I NJAVA*

*PLEASE INCORPORATE ALL OF STRING METHODS AND SCANNER METHOD LISTED IN THE DIRECTIONS BELOW*

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. The first and last names should be entered on the same input line i.e. there should be only one input to your program.

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 [] argsparameter of your program's main() method, when you first invoke the java command to run it.

Hints:

1: How the Scanner class is used can be seen in the Student class, under the Java Code folder here in Blackboard.

2:The Scanner method nextLine() will return the first and last names together at once, as one string, to your Initials class.

3: The String method String substring(int beginIndex, int endIndex) will allow you to isolate the initials in the full name.

4: The String method int indexOf(String str) will return the position of the space in between the first and last names. Use the string value/literal " " as your argument to this method to find the location of the space.

5: The index of the first position in a string is 0, not 1.

You can find the String api at http://docs.oracle.com/javase/7/docs/api/java/lang/String.html for further reference.

You can find out more about the Scanner class athttp://docs.oracle.com/javase/7/docs/api/java/util/Scanner.html .

IMPORTANT:

I would like to see good coding practises in your submission, e.g. correct naming conventions, a package name, get and set methods etc..

Answer 1

import java.util.*;

public class Initials

{

public static void main(String args[])

{

Scanner p=new Scanner(System.in);

System.out.println("Enter the name of the student: ");

String name = p.nextLine();

int n; //n is the position of space in the string

n=name.indexOf(" ");

System.out.println(name.substring(0,1)+" "+name.substring(n+1,n+2));

}

}
