Compile Java package in CMD

Question

i have a java application done in netbeans, and it has a package called my.alarm and it has an interface class called AlarmListener.java, an GUI class called AlarmGUI.java and a another class called Alarm.java which has all the methods implemented. so i would like to compile this package in command line instead of using netbeans. How do i do that ? the class paths were set and jdk was properly installed.

Answer 1

In Cmd line issue the following command

javac -d . *.java

make sure javac is in your path.

Answer 2

Since all your classes and dependencies resides in your only package, You could use something from your package directory like:

javac *.java

You could check the usage of javac (java compiler) and use as per your need further in addition to above:

Usage: javac <options> <source files>
where possible options include:
-g                         Generate all debugging info
-g:none                    Generate no debugging info
-g:{lines,vars,source}     Generate only some debugging info
-nowarn                    Generate no warnings
-verbose                   Output messages about what the compiler is doing
-deprecation               Output source locations where deprecated APIs are used
-classpath <path>          Specify where to find user class files and annotation processors
-cp <path>                 Specify where to find user class files and annotation processors
