Iterate over Enum in Java

enum Languages {
    JAVA, JAVASCRIPT, SWIFT, CPP,HTML
}
public class Main {
    public static void main(String[] args) {
        System.out.println("Access each enum constant");

        // use foreach loop to access each value of enum
        for(Languages language: Languages.values()) {
            System.out.print(language + ", ");
        }
    }
}

Access each enum constant
JAVA, JAVASCRIPT, SWIFT, CPP, HTML, 

• This program deals with the task of looping over an enum by utilizing for-each loop.
• For this purpose, we created a simple enum first.
• This enum is named Languages in this case, initialized by using enum keyword.
• It constitutes five constants JAVA, JAVASCRIPT, SWIFT, CPP and HTML.
• In the main method a message is displayed indicating that enum is being accessed.
• After that, in for-each loop the program iterates over Languages and displays each value using the values() method.
• This method is responsible for transforming enum constants into an array, in order to be displayed as elements of an array.

import java.util.EnumSet;
// create an enum
enum Languages {
    JAVA, JAVASCRIPT, SWIFT, CPP,HTML
}

public class Main {
    public static void main(String[] args) {

        // convert the enum Size into the enumset
        EnumSet<Languages> enumSet = EnumSet.allOf(Languages.class);
        System.out.println("Elements of EnumSet: ");
        // loop through the EnumSet class
        for (Languages constant : enumSet) {
            System.out.print(constant + ", ");
        }
    }
}

Elements of EnumSet:                                               
JAVA, JAVASCRIPT, SWIFT, CPP, HTML, 

• This program deals with the task of looping over an enum by utilizing EnumSet class.
• For this purpose, we created a simple enum first.
• This enum is named Languages in this case, initialized by using enum keyword.
• It constitutes five constants JAVA, JAVASCRIPT, SWIFT, CPP and HTML.
• In the main method we have used EnumSet class to create a set from the Languages enum.
• For this we specify the type of enum Languages, and fetch all the elements using the allOf() method provided by EnumSet class.
• After that, in for-each loop the program iterates over Languages and displays each value using the enumSet.
