String Index Out of Bounds with charAt

Question

As a school project, I have been asked to make a program that displays Initials of the name you enter(eg.for Akshat Abhay Shetye it would display A. A. Shetye).

This works fine on my school PC which runs a old bluej and Java but throws an error(StringIndexOutOfBoundsException: String index out of range) when I run it. This is my program:

import java.util.*;
import java.lang.*;
public class dispInitials{
    public static void main (String args[]){
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter your full name");
        String name = sc.next();
        //name = name.trim();
        String inName= name.charAt(0)+". ";
        int i = 1;
        for(i=1;i<(name.length()-1);i++){
            if(Character.isWhitespace(name.charAt(i)))
            break;
        }
        i++;
        inName=inName+name.charAt(i)+". ";
        for(i=i;i<name.length();i++){
            if(Character.isWhitespace(name.charAt(i)))
            break;
        }
        i++;
        System.out.println("The name is "+inName);
    }
}

Can anyone explain the error(at line 16)?

Answer 1

The error is in your name input.

Replace your input line with this code:

String name = sc.nextLine();
