Advanced Java and J2EE Module – 1 Enumerations, Autoboxing and Annotations 15CS553 Enumerations Enumerations was added to Java language in JDK5. Enumeration means a list of named constant. In Java, enumeration defines a class type. An Enumeration can have constructors, methods and instance variables. It is created using enum keyword. Each enumeration constant is public, static and final by default. Even though enumeration defines a class type and have constructors, you do not instantiate an enum using new. Enumeration variables are used and declared in much a same way as you do a primitive variable. How to Define and Use an Enumeration 1. An enumeration can be defined simply by creating a list of enum variable. Let us take an example for list of Subject variable, with different subjects in the list. enum Subject //Enumeration defined { Java, Cpp, C, Dbms } 2. Identifiers Java, Cpp, C and Dbms are called enumeration constants. These are public, static and final by default. 3. Variables of Enumeration can be defined directly without any new keyword. Subject sub; 4. Variables of Enumeration type can have only enumeration constants as value. We define an enum variable as enum_variable = enum_type.enum_constant; sub = Subject.Java; 5. Two enumeration constants can be compared for equality by using the = = relational operator. Example: if(sub == Subject.Java) { ... } Dept. of CSE, SJBIT Page 1
