Primitive Data Types as Parameters

The eight primitive data types are:

byte	short	int	long
float	double	char	boolean

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 );    
  }
}

First  value of the local var: 
Value of the parameter: 
Second value of the local var:
