public class One {
    int x;
    int y;

    void a() {
        b();
    }

    int b() {
        return this.x;  
    }

    int c() {
        return this.x + this.y; 
    }

    int d() {
        return e(this.y);
    }

    int e(int number) {
        return number * 2;
    }
}

This class have LCOM4 = 1, because the following members are linked:
