Write a Java Program to Iterate over enum
PROGRAM: Java Program to Iterate over enum
/*Java Program to Iterate over enum*/
1: Loop through enum using forEach loop
enum Size {
SMALL, MEDIUM, LARGE, EXTRALARGE
}
class Main {
public static void main(String[] args) {
System.out.println(“Access each enum constants”);
// use foreach loop to access each value of enum
for(Size size : Size.values()) {
System.out.print(size + “, “);
}
}
}
2: Loop through enum using EnumSet Class
import java.util.EnumSet;
// create an enum
enum Size {
SMALL, MEDIUM, LARGE, EXTRALARGE
}
class Main {
public static void main(String[] args) {
// create an EnumSet class
// convert the enum Size into the enumset
EnumSet<Size> enumSet = EnumSet.allOf(Size.class);
System.out.println(“Elements of EnumSet: “);
// loop through the EnumSet class
for (Size constant : enumSet) {
System.out.print(constant + “, “);
}
}
}
