If you guys have any suggestions or queries, feel free to drop a comment. But the persistent object facility went away, and along with it went the use of CAFEDEAD – it was eventually replaced by RMI. So CAFEBABE became the class file format, and CAFEDEAD was the persistent object format. I used CAFEDEAD for the object file format, and in grepping for 4 character hex words that fit after CAFE (it seemed to be a good theme) I hit on BABE and decided to use it.Īt that time, it didn't seem terribly important or destined to go anywhere but the trash-can of history.

I was re-vamping some file format code and needed a couple of magic numbers: one for the persistent object file, and one for classes.
Somewhere along the line it was noticed that this was a HEX number. When we used to go there, we referred to the place as Cafe Dead. When Jerry died, they even put up a little Buddhist-esque shrine. It was a pretty funky place that was definitely a Grateful Dead Kinda Place. According to local legend, in the deep dark past, the Grateful Dead used to perform there before they made it big. We used to go to lunch at a place called St Michael's Alley. However, James Gosling, the father of Java programming language, once explained it as follows: "CAFE BABE" was sexier than something like "A FAB CAFE" or "CAFE FACE", and definitely didn't like the implications of "CAFE A FAD" (or worse, "A BAD CAFE") The Java team wanted something with the Java-coffee metaphor, and since there's no 'J' or 'V' in hexadecimal, settled for something with CAFE in it.
1 byte for each pair) are easier to handle and more likely to be unique. What is the reason for choosing this specific Hexadecimal word CAFEBABE?Īs per Alastair Mayer, there are two reasons.ģ2-bit magic numbers (CA FE BA BE i.e.

You need to have editor which supports opening file in Hex format. class file directly in any text editor, it doesn't open in readable format. Any way, you don't need to worry about it, Java compiler will do that for you. So, CAFEBABE is must for getting your class file executed by any JVM. class files which starts with hex number CAFEBABE and it skips rest of the files. In other words, JVM will only read and executes. CAFEBABE) to make it easy to recognize as a valid class file and not something else. Well, the file has to start with some magic number or string (e.g. Why is it required to start each class file with magic number CAFEBABE? Similarly, Compiled Java class files (bytecode) start with Hexadecimal number CAFEBABE. JPEG image files begin with FF D8 and end with FF D9 Detecting such constants in files is a simple and effective way of distinguishing between many file formats and can yield further run-time information. Magic numbers are constant numbers or text value which is used to identify the file format. pdf) or some specific text in the starting content of each file. In computers, file type can either be identified by extension ( e.g.txt. What is the reason for choosing this specific word or number?.
