Java Class Constructor Implementation
< Prev
Next >

Consider the following class:

public class Time
{
    private int hrs;
    private int mins;
    private int secs;

    public Time()
    { /* implementation not shown */ }

    public Time(int h, int m, int s)
    { /* implementation not shown */ }

    /** Resets time to hrs = h, mins = m, secs = s. */
    public void resetTime(int h, int m, int s)
    { /* implementation not shown */ }

    /** Advances time by one second. */
    public void increment()
    { /* implementation not shown */ }

    /** Returns true if this time equals t, false otherwise. */
    public boolean equals(Time t)
    { /* implementation not shown */ }

    /** Returns true if this time is earlier than t, false otherwise. */
    public boolean lessThan(Time t)
    { /* implementation not shown */ }

    /** Returns a String with the time in the form hrs:mins:secs. */
    public String toString()
    { /* implementation not shown */ }
}

Which of the following represents correct implementation code for the constructor with parameters in the Time class?

A

Time = new Time(h, m, s);

B

hrs = h; mins = m; secs = s;

C

hrs = 0; mins = 0; secs = 0;

D

resetTime(hrs, mins, secs);
