Questions 1–3 refer to the Time class declared below: 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 */ } /** @return true if this time equals t, false otherwise */ public boolean equals(Time t) { /* implementation not shown */ } /** @return true if this time is earlier than t, false otherwise */ public boolean lessThan(Time t) { /* implementation not shown */ } /** @return 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?

Questions 1–3 refer to the Time class declared below: 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 */ } /** @return true if this time equals t, false otherwise */ public boolean equals(Time t) { /* implementation not shown */ } /** @return true if this time is earlier than t, false otherwise */ public boolean lessThan(Time t) { /* implementation not shown */ } /** @return a String with the time in the form hrs:mins:secs */ public String toString() { /* implementation not shown */ } } A client class has a display method that writes the time represented by its parameter: /** Outputs time t in the form hrs:mins:secs. * @param t the time */ public void display(Time t) { /* method body */ } Which of the following are correct replacements for / method body /? I Time T = new Time(h, m, s); System.out.println(T); II System.out.println(t.hrs + ":" + t.mins + ":" + t.secs); III System.out.println(t);

Which statement about parameters is false?

Questions 5–11 refer to the following Date class declaration: public class Date { private int day; private int month; private int year; public Date() //default constructor { ... } public Date(int mo, int da, int yr) //constructor { ... } public int month() //returns month of Date { ... } public int day() //returns day of Date { ... } public int year() //returns year of Date { ... } //Returns String representation of Date as "m/d/y", e.g. 4/18/1985. public String toString() { ... } } Which of the following correctly constructs a Date object in a client class?
