A Java compiler is a compiler for the Java programming language .
Some Java compilers output optimized machine code for a particular hardware/ operating system combination, called a domain specific computer system . An example would be the now discontinued GNU Compiler for Java . [ 1 ]
The most common form of output from a Java compiler is Java class files containing cross-platform intermediate representation (IR), called Java bytecode . [ 2 ]
The Java virtual machine (JVM) loads the class files and either interprets the bytecode or just-in-time compiles it to machine code and then possibly optimizes it using dynamic compilation .
A standard on how to interact with Java compilers was specified in JSR 199. [ 3 ]
It is provided by module jdk.compiler , and requires the full Java Development Kit (as opposed to just the Java Runtime Environment ), and reside in the javax.tools.* namespace. [ 4 ]

public class Example {
private final String TEST_FILE_NAME = "Test.java" ;
public static void main ( String [] args ) throws IOException {
File sourceFile = new File ( TEST_FILE_NAME );
if ( ! sourceFile . exists ()) {
throw new IllegalArgumentException ( String . format ( "File path %s does not exist!" , TIME_FILE_NAME ));
}
JavaCompiler compiler = ToolProvider . getSystemJavaCompiler ();
if ( compiler == null ) {
throw new RuntimeException ( "Compiler not available. Are you running on a JRE instead of a JDK?" );
}
int result = compiler . run ( null , null , null , sourceFile );
System . out . printf ( "Compilation result: %s%n" , result == 0 ? "Success" : "Failure" );
}
}
