read int form a file in java

I have a *.txt file that it has data like this:

  1222 25 36 25 14 25 25 36 363 25 15
    1253 69 54 87 54 285

first 17 chars of that are integer and others are binary.

now i want to read first 17 chars. how can i read them?

This is something you can do with a java.io.Scanner:

File f = new File("yourtxt.txt");
Scanner s = new Scanner(f);
for (int i = 0; i < 17 && s.hasNextInt(); ++i)
{
    int inputInteger = s.nextInt();
    // Handle your int here...
}

EDIT: The exception that is thrown is probably because of bytes you don't need between the integers.

Maybe you can try to do something like this:

DataInputStream dis = new DataInputStream(new FileInputStream(yourFile));
String numbers = dis.readLine() + " " + dis.readLine();
numbers = numbers.trim().replaceAll(" +", " ");
String[] array = numbers.split(" ");
for (int i = 0; i < array.length; ++i)
{
    int inputInteger = Integer.parseInt(array[i]);
    // handle inputInteger here...
}

I check it and it works

public static void main(String[] args){

        File f = new File("my.txt");

        if(f.exists()){
            Scanner scanner = null;
            try {
                scanner = new Scanner(f);            
            int [] arrayInt = new int [17];
            int i = 0;
            while(scanner.hasNextInt()){
                arrayInt[i++] = scanner.nextInt();
            }

            for(int tailElement : arrayInt){
                System.out.println(tailElement);
            }
            } catch (FileNotFoundException e) {
                e.printStackTrace(); 
            }
        }else{
            System.out.println("File not found!");
        }
}
