You are closing the Scanner stream in the InputInt()

Code:

in.close();

The problem is that once you close it, the stream is dead, so the next time you call it, it cant read from the command line (thats why it works on the first call of InputInt() but not the second.

One solution is to remove the in.close() and it will work fine. Another solution is the create an instance of the Input class and make InputInt non static:

Code:

import java.util.Scanner;

class Min {
	public static void main(String[] args) {
		int x = 0, y = 0, z = 0, f = 0, i = 0;
		Input input = new Input();
		
		x = input.InputInt();
		System.out.println(x);
		y = input.InputInt();
		System.out.println(x);
		
	}
}

class Input {
	public int InputInt() {
		int x = 0;
		Scanner in = new Scanner(System.in);

		// reads int from the console
		// and stores into x
		x = in.nextInt();

                // notice that now you can close the stream, since the method is non static
                in.close();

		return x;
	}

}

Thanks a lot. I just removed in.close(), and it worked, on the other hand it doesn't work, when I make non-static (I just copied your code)
