Java Program to Iterate over enum

Example 1: Loop through enum using forEach loop

Output 1

Access each enum constants
SMALL, MEDIUM, LARGE, EXTRALARGE, 

In the above example, we have an enum named Size. Notice the expression,

Size.values()

Here, the values() method converts the enum constants in an array of the Size type. We then used the forEach loop to access each element of the enum.

Example 2: Loop through enum using EnumSet Class

Output

Elements of EnumSet: 
SMALL, MEDIUM, LARGE, EXTRALARGE,

Here, we have used the allOf() method to create an EnumSet class from the enum Size. We then access each element of the enumset class using the forEach loop.
