What are Java enums?
An enum, short for enumerated type, is a variable type that can only take on the values that are declared inside the enum declaration. An enum is declared like a class, except the word "class" is replaced by the word "enum", and the class body is replaced by a list of values that a variable of that type can take on. You can also include methods, instance variables, and constructors in an enum.

The constants can be assigned any individual value but the following constant will always increment it by one.

How can you pass enum datatype as argument to function in c?
Here is the simple code, which demonstrates how you can use enum as function argument in c. =================================================== #include <stdio.h> // Enum declaration for power stat enum PowerStat{ OFF, ON } powerStat; // Function printing the stat of power supply void func( enum PowerStat ); int main(int argc, char* argv[]) { // Set power supply stat OFF powerStat = OFF; // Call function to print the stat func( powerStat); // Set power supply stat ON powerStat = ON; // Call function to print the stat func( powerStat); return 0; } void func( enum PowerStat stat) { printf("Power is = %s\n", stat ? "ON" : "OFF" ); } ================================================== I haven't compiled and run above code but it has to work fine. Let me know, if you found difficulty to compile it.

In c plus plus you cannot assign integer value to enum?
That is correct - In c plus plus you cannot assign integer value to enum - You can only assign an enum value to an enum. Even though an enum looks like an integer, it is not. It is an enum, and C++ implements strict type checking to reduce the probability of bad programming practices. enum ColorCode {black, brown, red, orange, yellow, green, blue, violet, grey, white}; ColorCode myColorCode; myColorCode = yellow; Even though yellow has an integer value of 4, you cannot say myColorCode = 4.
Enum in java?
Enum in java is a keyword which is introduced in JDK 1.5 and its a type like Interface and Class.Enum constants are implicitly static and final and you can not change there value once created. Enum in Java provides type-safety and can be used inside switch statment like int variables. Since enum is a keyword you can not use as variable name and since its only introduced in JDK 1.5 all your previous code which has enum as variable name will not work and needs to be refactored.
