javac and compiled class file

[Larsen Raja]

Hi,

Where would the compiled class file be usually geenrated?

As per K & B,

By default, the compiler puts a .class file in the same directory as the .java source file.

Consider the below case:

[img]
myProject
|
|--source
| |
| |-- MyClass.java
|
|-- classes
|
|--[/img]

And in this case, if I compile from MyProject directory where would the class be generated?

myProject> javac source/MyClass.java

If you compile from the myProjects directory and you want the class file to be compiled into the sources directory use should use the following command:

javac source/MyClass.java

However if you want the code to be compiled into a specific directory (for example the classes directory) you must specify it with the -d option tag like so:

javac -d classes source/MyClass.java

As you can see the K&B book is correct:

By default, the compiler puts a .class file in the same directory as the .java source file.

Shouldn't javac source/MyClass.java be creating class file in myProjects directory?

Can I conclude that always class files will be created in the source folder of .java file when compiled without -d option and from any directory?

javac - The Java Compiler says -

Unless you specify the -d option, the compiler places each class file in the same directory as the corresponding source file.
