Java pass value to class

After searching and reading a lot of examples about passing values/objects between classes/methods I still don't get it . . . Let's say i have this little code (which is wrong):

public class Main{
    public static void main(String[] args){
        Print print = new Print();
    }
}

//end of Main class

class ClassA{
    int x = 3;
    int y = 5;
    public classA(int a, int b){
        a = x;
        b = y;
    }
}
class ClassB{
    int c;
    public classB(int a, int b){
        c = a * b;
    }
}
class Print{
    int c;
    public Print(int c){
    System.out.println("C is equal to: " + c);
    }
}

This code example doesn't work but i want to understand once and forever how does passing values works in java. Thank you.

Add some int value when you instance Print like this:

  Print print = new Print(445);
