An important usage would be to find the compiler that is available in the current context. The method getSystemJavaCompiler() returns the Java compiler if available or else returns null.

import javax.tools.*;

public class JavaxTools
{
    public static void main(String[] args) 
   {
      JavaxTools javaxTools = new JavaxTools();
      javaxTools.proceed();
   }
   
   private void proceed()
   {
      System.setProperty( "java.home", "/usr/bin/java/jdk1.8.0_102");
      JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();      
      System.out.println(compiler);
   }
}

/*

Expected output:



[root@mypc]# java JavaxTools
com.sun.tools.javac.api.JavacTool@7d4991ad

Note: The output need not be same as the one specified here */
