Primitive Data Types as Parameters

The eight primitive data types are:

The word primitive means "a fundamental piece that is used to create other, larger parts." So far we have been using parameters with primitive data types. Here is a tiny program that reviews this:

class SimpleClass
{
  public void print( int x )
  {
    System.out.println("Value of the parameter: " + x );
  }
}

class SimpleTester
{
  public static void main ( String[] args )
  {
    int var = 7;
    SimpleClass simple = new SimpleClass();

    System.out.println("First  value of the local var: " + var );    
    simple.print( var );
    System.out.println("Second value of the local var: " + var );    
  }
}
