Grades()
{

range = "";

}

Grades(String str)
{

range = str;

}

Example D-4 illustrates how the enum type Grades works.

EXAMPLE D-4

public class EnumExample2
{

public static void main(String[] args)
{

System.out.println("Grade Ranges"); //Line 1

for (Grades gr : Grades.values()) //Line 2

System.out.println(gr + " "
+ gr.getRange()); //Line 3

System.out.println(); //Line 4

}

}

Sample Run:

Grade Ranges
A Range 90% to 100%
B Range 80% to 89.99%
C Range 70% to 79.99%
D Range 60% to 69.99%
F Range 0% to 59.99%
The foreach loop in Line 2 uses the method values to retrieve the enum constants as a
list. The method getRange in Line 3 is used to retrieve the string contained in the
Grades object.

The following programming example uses an enum type to create a program to play the
game of rock, paper, and scissors.
