{
public static void main( String notused[] ) throws MapleException
String[] mapleArgs = { "java" };
Engine engine = new Engine( mapleArgs, new EngineCallBacksDefault(), null, null );
Algebraic a1 = engine.evaluate( "1:" );
if ( a1.isStop() )
System.out.println( "Stop" );
}
else
System.out.println( "Not Stop" );
a1 = engine.evaluate( "quit:" );
Executing this code should produce the following output.
