Java - cut string in a specific way

Iothin :

I have a string (taken from file):

Computer: intel, graphic card: Nvidia,

Mouse: razer, color: white etc.

I need to take words between ":" and ",".

When I'm doing this in that way

Scanner sc = new Scanner(new File(path));
    String str = sc.nextLine();

    ArrayList<String> list = new ArrayList<String>();

    while (sc.hasNextLine()) {

        for (int i = 0; i < str.length(); i++) {
            list.add(str.substring(str.indexOf(":"), str.indexOf(",")));
        }
        System.out.println("test");

        sc.nextLine();

    }

I'm only taking ": intel". I don't know how to take more word from same line and them word from next line.

Assuming the content of the file, test.txt is as follows:

Computer: intel, graphic card: Nvidia
Mouse: razer, color: white

The following program will

import java.io.File;
import java.io.FileNotFoundException;
import java.util.ArrayList;
import java.util.Scanner;

class Coddersclub {
    public static void main(String[] args) throws FileNotFoundException {
        Scanner sc = new Scanner(new File("test.txt"));
        ArrayList<String> list = new ArrayList<String>();
        String str = "";
        while (sc.hasNextLine()) {
            str = sc.nextLine();
            String[] specs = str.split(",");
            for (String item : specs) {
                list.add(item.substring(item.indexOf(":") + 1).trim());
            }
        }
        System.out.println(list);
    }
}

output:

[intel, Nvidia, razer, white]

Note: if you are looking for the list to be as [: intel, : Nvidia, : razer, : white], replace list.add(item.substring(item.indexOf(":") + 1).trim()); with list.add(item.substring(item.indexOf(":")).trim());.

Feel free to comment if you are looking for something else.
