How to loop an enum in Java

Call the .values() method of the enum class to return an array, and loop it with the for loop:

	for (EnumClass obj : EnumClass.values()) {
		System.out.println(obj);

For Java 8, convert an enum into a stream and loop it:

	Stream.of(EnumClass.values()).forEach(System.out::println);

1. For Loop Enum

1.1 An enum to contain a list of the popular JVM languages:

package com.mkyong;
public enum Programming {
    CLOJURE,
    GROOVY,
    JAVA,
    KOTLIN,
    SCALA

1.2 To loop over the above enum class, just call .values() and do a normal for loop

package com.mkyong;
public class Main {
    public static void main(String[] args) {
        for (Programming obj : Programming.values()) {
            System.out.println(obj);

Output

CLOJURE
GROOVY
JAVA
KOTLIN
SCALA

2. Java 8 Stream APIs

2.1 Convert an enum into a stream and filter out the SCALA

package com.mkyong;
import java.util.stream.Stream;
public class Main {
    public static void main(String[] args) {
        Stream.of(Programming.values())
                .filter(x -> !x.toString().equals("SCALA"))
                .forEach(System.out::println);

Output

CLOJURE
GROOVY
JAVA
KOTLIN
