New to Java and not sure how to start my assignment using scanner, length method, and substring method

**JavaNewbie14** · September 29th, 2014, 11:53 PM

note: I have not taken any cpu/java classes besides the one I am currently enrolled in. I am currently in a computer science 101 class for java. I am not asking for you to do my homework assignment for me, but to help me get started/understand. Thank you.

My assignment is to ask the user to enter a string
Then to display the length of their string, as well as to ask which numbers they want to look between.
After they enter which numbers they want to look between, it must then display what words/letters are within those 2 numbers.

Example:
Enter a string:
I love coffee

The length of the string is: 13
Enter the numbers you want to look between
2
5

The part of the string between 2 and 5 is: love

My instructor hinted that we will be using scanner, length method, and substring method

Hi,

post your code and ask specific questions. It's hard to help you without knowing where you are stuck. Break the assignment down to small bits, start with getting the user input. Read the API docs your instructor has mentioned.

this is what i have so far. now how do i use the substring method so that the user can input 2 integers and then display the part of the string between those 2 integers?

import java.util.Scanner;
 
class Strings
{
     public static void main(String[] args)
     	{
			System.out.println("Enter a string, then hit enter.");
 
		 	Scanner keyboard = new Scanner(System.in);//Scanner is titled keyboard
		 	String userString = keyboard.nextLine();//String inputed by user is titled userString
			int count = userString.length();
			System.out.println("\nYour string has a length of " + userString.length() + ". Enter the numbers you want to look between.");
 
		}
}

Have you read the String API to see how to use the substring() method? Start there.
