class Example
{
public static void main( String notused[] ) throws MapleException
String[] mapleArgs = { "java" };
Engine engine = new Engine( mapleArgs, new EngineCallBacksDefault(), null, null );
Table t = (Table)engine.evaluate( "table([(1)=100,(2)=200,(3)=300,(4)=400]):" );
System.out.println( t.get( engine.newNumeric( 1 ) ) );
System.out.println( t.get( engine.newNumeric( 2 ) ) );
System.out.println( t.get( engine.newNumeric( 3 ) ) );
System.out.println( t.get( engine.newNumeric( 5 ) ) );
}
Executing this code produces the following output.
100
200
300
null
