Questions tagged [compiler-options]

Compiler-options are parameters that are being passed to the compiler and that affect the compilation process or its resulting product.

Modern compilers have a large set of options that can be used to somehow change the way the code is compiled. Usually those options are passed as command-line flags.

javac -target 1.5 -bootclasspath jdk1.5.0\lib\rt.jar \ -extdirs "" OldCode.java

More information about particular options can be found on compiler vendor's websites, to name a few:
