4. Enum name() The name() method returns the defined name of an enum constant in string form. The returned value from the name() method is final. For example, name(SMALL) // returns "SMALL" 5. Java Enum valueOf() The valueOf() method takes a string and returns an enum constant ...
For example, the string"RED"will be converted toColorsEnum.REDlike this: ColorsEnumcolor=ColorsEnum.valueOf("RED");System.out.println(color);// REDSystem.out.println(color==ColorsEnum.RED);// true Please note that thevalueOf()method accepts only aStringtype value and is case-sensitive. ...
ThevalueOf()method is also a static method that takes a string as an argument and returns the enum constant with the corresponding name. For example,Day.valueOf(“SUNDAY”)would return the enum constantSUNDAY. Thename()method returns the name of the enum constant, exactly as declared in its...
2. Example of Enum with Multiple Values In the given example, we are creating an enumAccountStatus. In our application, we can denote an account’s status with any of the multiple values. For instance, we can indicate an active status with the strings “A“, “active" and even aninteger...
// Java program to demonstrate the example // of T valueOf(Class<T> en_ty , String en_name) // method of Enum enum Month { JAN, FEB, MAR, APR, MAY; } public class ValueOf { public static void main(String args[]) { Month m1 = Month.valueOf("JAN"); Month m2 = Month.value...
(Refer the constructorDirectionsin the above example) with the passed argument. This way the passed value is set as an value for the field of the corresponding enum’s constant [EAST(“E”)=>Would call constructor Directions(“E”)=>this.shortCode = code=>this.shortCode = “E”=>...
Return value:The return type of this method is T, it returns enum constant along with the given enum name.Example:// Java program to demonstrate the example // of T valueOf(Class<T> en_ty , String en_name) // method of Enum enum Month { JAN, FEB, MAR, APR, MAY; } public ...
