 @Deprecated(since="9", forRemoval=true) public final class Compiler extends Object Deprecated, for removal: This API element is subject to removal in a future version.JIT compilers and their technologies vary too widely to be controlled effectively by a standardized interface. As such, many JIT compiler implementations ignore this interface, and are instead controllable by implementation-specific mechanisms such as command-line options. This class is subject to removal in a future version of Java SE.TheCompilerclass is provided to support Java-to-native-code compilers and related services. By design, theCompilerclass does nothing; it serves as a placeholder for a JIT compiler implementation. If no compiler is available, these methods do nothing.- Since:
