building constructors with new variables in java

I was asked to write a class called BusArrival, while BusArrival has only one private instance - Time1 _arrivalTime. (which is a class wrote, but it's not what my question is about).

Then I needed to call for a constructor in BusArrival.

private Time1 _arrivalTime;

public BusArrival(int h, int m ,int s) {
    if (h < 23 && h > 0)
        h = h;
    else 
        h = DEFAULT_HOUR;

    if (m < 60 && m > 0) 
        m = m;
    else 
        m = DEFAULT_MINUTE;

    if (s < 60 && s > 0)
        s = s;
    else 
        s = DEFAULT_SECOND;
}

but when I do that h, m and s are always returning as 0. if I do the same using Time1 h, s and m it's working fine.

How do I use variables in constructors that I don't already have defined?

If you would like to preserve h, m, s for the object you create declare as private members too, and instead of writing

h = h; 

write

this.h = h;

add the following declarations:

private int h, m, s;
