indexOf(String str) question:

[jocdrew21]

Line 23 is failing and I am not to sure why. I made a method and I am trying to use it in main. Simple task but it is saying I need to initialize it but if I initialize it to null it fails too.

import java.util.*; 

public class ParseInput 
{
	String myline = "Learning Java is fun. Java is portable";
	
	int findPosition(String str)
	{
		int a = myline.indexOf(str); //finds position of a word return the int position or -1 if not found
		
		return a;
	}
	
public static void main(String[] args)
{
	Scanner input = new Scanner(System.in);
	System.out.println("What word would you like to find"); //prompt statement to user
	String word=input.next(); //user input
	
	ParseInput v;
	
	int result;
	result=v.findPosition(word);
	
	input.close();
	
	if(result >= 0)
	{ System.out.println("The position of is located at "+result);}
	else
	{System.out.println("The word is not in the sentence."); }
}

}

You need to initialize your v variable to be an instance of the ParseInput class. You do that using the new keyword.

ParseInput v = new ParseInput();

This is exactly what you're doing with your Scanner variable: initializing it to an instance of a class using the new keyword before you use it.

What error do you get exactly? Could you provide an example input that fails? Don't forget, java is case sensitive.
