Question

Task #4: Writing value returning Methods

In this task, you are being asked to write value returning methods in Java.

Write a method called charAtPosition() that accepts two arguments: a String object, and a 

positive integer. It then returns the character located at position given by the integer argument.

You may use the following header for this method:

static char charAtPosition(String word, int position)

For example, if the method is called with the arguments, "GIFT University" and 5, the method 

returns the character ‘U’ and a sample output should be:

Character at position 5 is: U

NOTE: A String starts from character position 0. Also, perform input validation so that the 

position must be greater than or equal to 0.

HINT: Use the charAt(index) method of the String to find the character in a String. 

1. Create a program called CharacterPositionLab1.java. 

2. Correctly call the method with appropriate arguments. 

3. Correctly display appropriate messages.

Answer 1

import java.util.Scanner;


public class CharacterPositionLab1{
    static char charAtPosition(String word, int position){
        return word.charAt(position);
    }
    public static void main (String [] args){
        Scanner input = new Scanner(System.in);
        System.out.print("Enter a word:");
        String word = input.nextLine();
        System.out.print("Enter a position: ");
        int position = input.nextInt();
        if(position>=0 && position<word.length()){
            System.out.printf("Character at position %d is: %c\n\n",position,charAtPosition(word,position));    
        }else{
            System.out.printf("Wrong position\n");
        }
        
        input.close();
    }
}
