CH11 – Getters and Setters

  1. If you haven’t completed the previous exercises in this chapter, do so now.
  2. Open TheTimeClass.java and add the following methods. These are getters and setters.
public void setHour(int hour){
  this.hour = hour;
}
public void setMinute(int minute){
  this.minute = minute;
}
public void setSecond(int second){
  this.second = second;
}
public int getHour(){
  return this.hour;
}
public int getMinute(){
  return this.minute;
}
public int getSecond(){
  return this.second;
}
  1. Close TheTimeClass.java
  2. Create a new class named TimeClient in a new file and add a the following code to a main method.
public class TimeClient {
  public static void main(String[] args){
    TheTimeClass myTime = new TheTimeClass();
    myTime.setHour(12);
    myTime.setMinute(32);
    myTime.setSecond(45);

    String timeString = myTime.getHour() + ":" + myTime.getMinute() + ":" +
      myTime.getSecond();

    System.out.println(timeString);
    
  }
}
  1. Compile both classes and run the program.
$ javac TheTimeClass.java
$ javac TimeClient.java
$ java TimeClient
