Answer:

Data Type	Primitive	Class
int	X
String		X
long	X
double	X
Applet		X
boolean	X
Scanner		X

The correct way to do this is to recognize the primitive data types. Everything else must be a class. Class names usually begin with a capital letter, but this is not required by syntax.

A Primitive Variable

Here is a tiny program that uses a primitive data type:


class EgLong
{
  public static void main ( String[] args )
  {
    long value;

    value = 18234;
    System.out.println( value );
  }
}

In this program, the variable value is the name for a 64 bit section of memory that is used to hold long integers. The statement

value = 18234;

puts a particular bit pattern in that 64 bit section of memory.

With primitive data types, a variable is a section of memory reserved for a value that uses that data type. For example by saying long value, 64 bits of memory are reserved for an integer. By saying int sum, 32 bits of memory are reserved an integer.

Object reference variables do not work this way, however. The next several pages will discuss this.
