What is the –release flag in the Java 9 compiler?
Not exactly. JEP 247: Compile for Older Platform Versions defines this new command-line option, –release: We defined a new command-line option, –release, which automatically configures the compiler to produce class files that will link against an implementation of the given platform version. For the platforms predefined in javac, –release N is equivalent to -source N … Read more
javac error: Class names are only accepted if annotation processing is explicitly requested

javac not working in windows command prompt
If you added it in the control panel while your command prompt was open, that won’t affect your current command prompt. You’ll need to exit and re-open or simply do: set “path=%path%;c:\program files\java\jdk1.6.0_16\bin” By way of checking, execute: echo %path% from your command prompt and let us know what it is. Otherwise, make sure there … Read more
How to add -Xlint:unchecked to my Android Gradle based project?

javac option to compile all java files under a given directory recursively
I would also suggest using some kind of build tool (Ant or Maven, Ant is already suggested and is easier to start with) or an IDE that handles the compilation (Eclipse uses incremental compilation with reconciling strategy, and you don’t even have to care to press any “Compile” buttons). Using Javac If you need to … Read more
What is the difference between javac and the Eclipse compiler?
Eclipse has implemented its own compiler called as Eclipse Compiler for Java (ECJ). It is different from the javac, the compiler that is shipped with Sun JDK. One notable difference is that the Eclipse compiler lets you run code that didn’t actually properly compile. If the block of code with the error is never ran, … Read more
Why does a Java class compile differently with a blank line?
Basically, line numbers are kept for debugging, so if you change your source code the way you did, your method starts at a different line and the compiled class reflects the difference.
In which language are the Java compiler and JVM written?
The precise phrasing of the question is slightly misleading: it is not “the JVM” or “the compiler” as there are multiple JVM vendors (jrockit is one, IBM another) and multiple compilers out there.
