class Example
{
public static void main( String notused[] ) throws MapleException
String[] mapleArgs = { "java" };
Engine engine = new Engine( mapleArgs, new EngineCallBacksDefault(), null, null );
List s = (List)engine.evaluate( "[2,5,8,exp(2*x)];" );
Object[] arr = s.toArray();
for (int i = 0; i < arr.length, i++)
System.out.println( "Element " + i + ": " + arr[i] );
}
Algebraic[] algArray_in = new Algebraic[1];
Algebraic[] algArray_out = s.toArray( algArray_in );
Executing this code produces the following output:
Element 0: 2
Element 1: 5
Element 2: 8
Element 3: exp(2*x)
