How to parse String to Enum in Java | Convert Enum to String with Example (original) (raw)

Converting Enum into String and parsing String to Enum in Java is becoming a common task with the growing use of Enum. Enum is very versatile in Java and preferred the choice to represent bounded data and since is almost used everywhere to carry literal value it's important to know how to convert Enum to String in Java. In this article, we will see both first converting Strings to Enum in Java and then Change an Enum to String in Java with Example. I thought about this Enum tutorial when I wrote 10 Examples of Enum in Java. I missed String to Enum conversion and one of the readers pointed out that. So here we have now.

Enum to String to Enum in Java

Convert Enum to String in Java Example

Enum classes by default provide the valueOf (String value) method which takes a String parameter and converts it into an enum. String name should match with the text used to declare Enum in the Java file. Here is a complete code example of String to Enum in Java

Code Example String to Enum:

/**

* Java Program to parse String to Enum in Java with examples.

*/

public class EnumTest {

private enum LOAN {

HOME_LOAN {

@Override

public String toString() {

return "Always look for cheaper Home loan";

}

},

AUTO_LOAN {

@Override

public String toString() {

return "Cheaper Auto Loan is better";

}

},

PEROSNAL_LOAN{

@Override

public String toString() {

return "Personal loan is not cheaper any more";

}

}

}

public static void main(String[] args) {

// Exmaple of Converting String to Enum in Java

LOAN homeLoan = LOAN.valueOf("HOME_LOAN");

System.out.println(homeLoan);

LOAN autoLoan = LOAN.valueOf("AUTO_LOAN");

System.out.println(autoLoan);

LOAN personalLoan = LOAN.valueOf("PEROSNAL_LOAN");

System.out.println(personalLoan);

}

}

Output:

Always look for cheaper Home loan

Cheaper Auto Loan is better

Personal loan is not cheaper anymore

Convert Enum to String in Java Example

Now let's do the opposite convert an Enum into String in Java, there are multiple ways to do it one way is to return the exact same String used to declare Enum from toString() method of Enum, otherwise if you are using toString() method for another purpose then you can use default static name() method to convert an Enum into String.

Java by default adds the name() method into every Enum and it returns exactly the same text which is used to declare enum in a Java file.

Code Example Enum to String

public static void main(String[] args) {

// Java example to convert Enum to String in Java

String homeLoan = LOAN.HOME_LOAN.name();

System.out.println(homeLoan);

String autoLoan = LOAN.AUTO_LOAN.name();

System.out.println(autoLoan);

String personalLoan = LOAN.PERSONAL_LOAN.name();

System.out.println(personalLoan);

}

Output:

HOME_LOAN

AUTO_LOAN

PERSONAL_LOAN
