javac

A Java program is initially compiled through the Java SDK's javac program into a native platform-neutral format known as class files.

And, now that javac is open source, it is possible the features might be supported by a third party.

In fact, I purposely created it with just a Java editor, Wordpad for the files, javac, and the jar command.

java and --javac allow you to generate "real" Java classes from Ruby classes in a given file.

Enumerations: The JSR 14 target mode of javac has no special support for enumerations.

There shouldn't be too many surprises here, other than some of the niceties that the javac compiler added on your behalf.

In my opinion, any Lombok extension needs to support both javac and ECJ, at least for now.

Make sure the file extension ends in . aj, but don't attempt to compile it with the normal javac.

In between the do and the end of my javac task is where all the magic happens.

By default, the javac compiler thinks all of these are the current working directory, which is almost never what you want.

AspectJ comes with an Ant task, dubbed iajc, that acts like javac; however, this process compiles and weaves aspects into subject code.

If javac were a pluggable compiler, you could instruct it to compile both your Groovy and Java files at the same time.

xjc is an extended javac compiler that understands XML Schema, XPath expressions, and XML.

You can use one of two flags with the javac command: -deprecated or the new -Xlint: deprecated flag.

Android apps are written in the Java(TM) language, and compiled by the JDK's javac compiler (or equivalent, like ECJ).

Code using javac or ECJ APIs is not trivial to read and understand.

Lombok uses non-public APIs in both javac and ECJ to accomplish its clever code-generation technique.

I've included tests for both javac and ECJ annotation handlers in this article's sample code (see Download).

Assuming there are no syntax errors, javac places the compiled . class file in the same directory where the . java file is.

The Iterable options allow the client to pass additional compiler options that correspond to the javac options.

In one future, Duby becomes a widely-used, general-purpose replacement for Java and javac.

For all you lazy developers who have happily forgotten the cryptic syntax of java and javac, a useful Ant task is also available.

String concatenation: The JSR 14 target mode of javac causes the compiler to generate calls to StringBuffer instead of StringBuilder.

Sadly, the javac compiler will do exactly that unless you're careful.

But in this style-called the @AspectJ model-aspects can be compiled using javac.

Javac is the default compiler used by build tools like Ant and Maven.

After doing the above work, use the following command to start the program: javac-classpath " new grapro directory parent directory" grapro.

Tag file source is compiled when the including JSP is processed by javac.

This tip is useful only if you decide to support both javac and ECJ.

The good news is that the Lombok team has done a fairly good job of documenting how they use javac and ECJ to generate AST nodes.

Compile the Java code using the command-line Java tool javac.

Going back to our use of "javac" , after compiling the source code we probably want to run it, with a command such as "java TestProgram" .

Because it's not, you can simply wrap the javac task in Ant with a groovyc task.

Compile wsdlcpp using the command javac wsdlcpp. java.

This class, on the other hand, can be compiled using javac and applied by Spring.

I want a language that can replace javac in producing free-standing Java . class files.

Now the program compiles without error and produces the output shown in Figure 4. Notice that javac also compiled the file Fraction. java

Retroweaver came first, and it handled all the cases handled by javac -target JSR 14, and a few more

Compiling this code (javac HelloJavaSwing. java) and running it (java HelloJava) should yield an application as shown in Figure 1

To run the test, you compile the class with javac and then invoke TestNG with the following command

Annotations handlers (for both javac and ECJ) that generate the "bound" setter

Open a command window and compile by executing: javac InfiniteLoop. java. (Use any javac available. )

The JSR 14 target mode of javac causes the compiler to emit JDK 1. 4-compatible bytecode corresponding to Java 5 language features
