Prolog连接到Java

Question

I have an expert system similar to animal identification mold. This program can be run independently in prolog, now I want to build a GUI for it based on java using netbeans. I know how to do the first query to consult the file:

private void startDiagnose(){
  Term consult_arg[] = { 
          new Atom( "C:/Users/Adrian/Desktop/WOU/wou.pl" ) 
      };
      Query consult_query = 
          new Query( 
              "consult", 
              consult_arg );

      boolean consulted = consult_query.query();

      if ( !consulted ){
          System.err.println( "Consult failed" );
          System.exit( 1 );
      }

But how can I do the second query: "-? go." ( By typing in "go." in prolog the program can be run with asking user questions, and user answer should be (Y/N.)to continue the following questions)

Answer 1

You can execute second query in the same way you executed the first one.

Query second_query = new Query("go");

consulted = second_query.query();

if ( !consulted ){
  System.err.println( "Consult failed" );
  System.exit( 1 );
}
