Parameters

key

-

index to associate with the value

val

-

value to assign into the table

• 

If a value is already assigned to the index key, it is overwritten by val.

Examples

import com.maplesoft.openmaple.*;

import com.maplesoft.externalcall.MapleException;

class Example

{

    public static void main( String notused[] ) throws MapleException

    {

        String[] mapleArgs = { "java" };

        Engine engine = new Engine( mapleArgs, new EngineCallBacksDefault(), null, null );

        Table t = engine.newTable();

        System.out.println( t );

        t.assign( engine.newNumeric( 1 ), engine.newNumeric( 100 ) );

        t.assign( engine.newNumeric( 2 ), engine.newNumeric( 200 ) );

        t.assign( engine.newNumeric( 3 ), engine.newNumeric( 300 ) );

        t.assign( engine.newNumeric( 4 ), engine.newNumeric( 400 ) );

        System.out.println( t );

        t.assign( engine.newNumeric( 3 ), engine.newNumeric( 600 ) );

        t.assign( engine.newNumeric( 4 ), engine.newNumeric( 700 ) );

        System.out.println( t );

    }

}

Executing this code produces the following output.

table([])

table([(1)=100,(2)=200,(3)=300,(4)=400])

table([(1)=100,(2)=200,(3)=600,(4)=700])
