Describe how to use for loops with enum types.

"values()" method:

• The static method “values()” of the “java.lang.Enum” class provides an array of “enum” values.
• Iteration over the array can be accomplished using “for” loop.

Description of “for” loop is given as follows:

• The “for” loop is a way of writing the loop in a concise manner.
• The “for” loop use the initialization, condition and increment or decrement in a single line.
• The “for” loop provides the shorted and the easiest way to debug a loop structure.

The syntax of for loop is given as follows:

for (initialization_loop; condition ; increment/decrement)

{

            //Statements

}

Example with the role of “enum” is as follows:

File name: “Sample.java”

//Define the main class

public class Sample

{

      //Define the enums

      enum weekdays

      {

            //Define the days.

            Monday, Tuesday, Wednesday, Thursday

      }

      //Define the main() function

      public static void main(String[] args)

      {

            //Begin the for loop to traverse the enum of days

            for (weekdays day : weekdays.values())

            {

                  //Display the days

                  System.out.println(day);

            }

      }

}
