Answer 1

According to your problem description : you can use taking user input instead of random number generation. If the input number is not within the range as expected, continue asking user input again or raise error.

coordinates[i] = new Random().nextInt(gameLength);
I only found this where you are using random() so instead this write
do
{
coordinates[i] = new Scanner(System.in).nextInt();
}while(coordinates[i] >gameLength);

You have tricky code that can't be tested here. Accoding to your code, it will return to calling statement. But also you can create only one object of Scanner so create object of scanner as static or class level object.. It works then I think.
