COMPILING JAVA WITH DOS FORMAT GENERATOR
JavaCC The most popular parser generator for use with Java applications.
So using the -verbose option can tell us what the compiler is doing: javac -verbose MyProgram.JavaCC | The most popular parser generator for use with Java applications. The compiler can compile source files which are related to the specified one, and it does that silently. The target VM version must be greater than or equal the source version, that’s why we specify both the options -target and -source here.īy default, the target VM version is the version of the compiler. Using the -target release option we can do this, for example: javac -target 1.6 -source 1.5 MyProgram.java class files for a specific Java virtual machine (VM) version. That will tell the compiler using specific language features in Java 1.5 to compile the source file. For example: javac -source 1.5 MyProgram.java We can tell the compiler which Java version applied for the source file, by using the -source release option. Specify Java source compatibility version That will compile the MyProgram.java file in the src directory. For example: javac -sourcepath src MyProgram.java
We can tell the compiler where to search for the source files by using the -sourcepath directoryoption. If the source file is under a package, the compiler will create package structure in the destination directory.The compiler will complain if the specified directory does not exist, and it won’t create one.For example: javac -d classes MyProgram.java Use the -d directoryoption to specify where the compiler puts the generated. Or we can use the wildcard character *: javac -cp * MyProgram.javaThat will instruct the compiler to look for all available libraries in the same directory as the source file. Compile a source file which depends on multiple libraries: javac -cp lib1.jar lib2.jar lib3.jar MyProgram.java.Compile a source file which depends on an external library: javac -classpath mail.jar EmailSender.java.Use the flag -classpath (or -cp) to tell the compiler where to look for external libraries (by default, the compiler is looking in bootstrap classpath and in CLASSPATH environment variable). It’s very common that a Java program depends on one or more external libraries (jar files). Compile a Java source file which has dependencies Compile all source files whose filenames start with Swing:.Javac Program1.java Program2.java Program3.java Compile three source files at once, type:.Compile a single Java source file javac HelloWorld.java 2. class files are placed under the same directory as the source files.ġ. Type javac -help to view compiler options, and type javac -version to know current version of the compiler.
All the commands below are supposing the current working directory is where the source files are placed. So make sure you included this directory in the PATH environment variable so it can be accessed anywhere in command line prompt.This tutorial summarizes common practices for compiling Java source files from command line. The tool is located under JDK_HOME\bin directory. You know, the Java Development Kit (JDK) provides javac which is the Java compiler program. Specify Java source compatibility version.Compile a Java source file which has dependencies.

In this Java tools tutorial, you will learn how to use the Java compiler via the javac command to compile Java source files (.java) into bytecode files (.class).
