Given an enum containing a group of constants, the task is to convert the enum to a String.
Methods:
We can solve this problem using two methods:
- Using name() Method
- Using toString() Method
Let us discuss both of them in detail and implementing them to get a better understanding of the same.
Method 1: Using name() Method
It returns the name of the enum constant same as declared in its enum declaration.
- We would be using name() method to return the name of the enum constant.
- In the main class, we just have to print it.
- The value given inside is first the name of the enum class that we will create further, then calling the constant that is named, finally using the name() method.
- Now create another java enum file named Fruits.java in the same folder where you created the main file, and declare the enum as follows:
Example
public enum Fruits {
Orange, Apple, Banana, Mango;
}
Java
// Java Program to Convert Enum to String// using // Importing input output classesimport java.io.*; // Enumenum Fruits { Orange, Apple, Banana, Mango;} // Main classclass GFG { // Main driver method public static void main(String[] args) { // Printing all the values System.out.println(Fruits.Orange.name()); System.out.println(Fruits.Apple.name()); System.out.println(Fruits.Banana.name()); System.out.println(Fruits.Mango.name()); }} |
Output
Orange Apple Banana Mango
Method 2: Using toString() Method
It is used to get a string object which represents the value of the number object.
- We will be following the same procedure as earlier used but the only difference here is that we will be using toString() method. So just replace name() method with toString() method.
Note: Do not forgot to create a Fruits.java enum file in the same folder.
Illustration:
public enum Fruits {
Orange, Apple, Banana, Mango;
}
Example 2
Java
// Java Program to Convert Enum to String// Using toString() Method // Importing input output classes import java.io.*; // Enumenum Fruits { // Custom entries Orange, Apple, Banana, Mango;} // Main class class Main { // Main driver method public static void main (String[] args) { // Printing all the values System.out.println(Fruits.Orange.toString()); System.out.println(Fruits.Apple.toString()); System.out.println(Fruits.Banana.toString()); System.out.println(Fruits.Mango.toString()); }} |
Output
Orange Apple Banana Mango
