Thread: question about indexes

So I was wondering if it is possible to stores indexes as variables. I have a question where the user inputs a string such as the fox [who is red] must have left earlier.
The problem is to return only what is in the [] including the brackets and the second question is to get the length of that part. Does anyone know how to do this? I was figuring if I could store the indexOf [ and the lastIndexOf ] stored those values as variables and then used them in a substring method (a,b) but I don't know how to do that or if it's even possible. Thanks

Of course you know how to store values in variables. Start writing the code and hopefully your "block" about storing a value will disappear as you write. Come back with your code when you need help.

import java.util.Scanner;

public class Help
{
public static void main(String [] args)
{
Scanner in = new Scanner(System.in);
String abc;
int ind1, ind2;

System.out.println("Enter a sentence with a substring in [] brackets: ");
abc = in.nextLine();

ind1 = int abc.indexOf([);



}
}
I'm not sure how to set up the variable with the proper syntax

Please post your code in code tags.

Sometimes you try something and it doesn't work, so you try something else. Sometimes you read the documentation and increase the chances that the first thing you try will work.

Refer to the String API, and note that the method String.indexOf() returns an int. Knowing that, you can use correct syntax, like:

int leftBraceIndex = userString.indexOf( '[' );

Thanks

You're welcome.
