boolean isShort() throws MapleException

{
public static void main( String notused[] ) throws MapleException
String[] mapleArgs = { "java" };
Engine engine = new Engine( mapleArgs, new EngineCallBacksDefault(), null, null );
Numeric n = (Numeric)engine.evaluate( "2^18:" );
System.out.println( n.isShort() );
try
n.shortValue();
}
catch ( MapleException me )
System.out.println( me.getMessage() );
n = (Numeric)engine.evaluate( "2^14:" );
short s = n.shortValue();
System.out.println( s );
Executing this code produces the following output.
