Java Program to Iterate over enum
In this article, we will understand how to iterate over enum objects. Enum is a datatype that represents a small collection of objects.
Below is a demonstration of the same −
Input
Suppose our input is −
Enum objects are defined as : red, blue, green, yellow, orange
Output
The desired output would be −
Printing the Objects: red blue green yellow orange
Algorithm
Step 1 – START Step 2 - Declare the objects of Enum function namely red, blue, green, yellow, orange Step 3 – Using a for loop, iterate over the objects of the enum function and print each object. Step 4- Stop
Example 1
enum Enum {
red, blue, green, yellow, orange;
}
public class Colour {
public static void main(String[] args) {
System.out.println("The values of Enum function are previously defined .");
System.out.println("Accessing each enum constants");
for(Enum colours : Enum.values()) {
System.out.print(colours + "\n");
}
}
}Output
The values of Enum function are previously defined . Accessing each enum constants red blue green yellow orange
Example 2
Here is an example to print the days of the week.
import java.util.EnumSet;
enum Days {
Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday
}
public class IterateEnum{
public static void main(String args[]) {
Days my_days[] = Days.values();
System.out.println("Values of the enum are: ");
EnumSet.allOf(Days.class).forEach(day -> System.out.println(day));
}
}Output
Values of the enum are: Sunday Monday Tuesday Wednesday Thursday Friday Saturday
