Java Class Example

• Given the following class definition:

  class MyClass {
      int counter;
      int getCounter () { return counter; }
      void setCounter ( int val ) {counter = val; }
  }

• class instance variables and methods are used as follows:

  class Test {
      public static void main (String args[]) {
          MyClass myinstance = new MyClass();
          int myval;
          myinstance.setCounter(20);
          myval = myinstance.getCounter();
          System.out.println("Counter = " + myval);
      }
  }
