How do I get the java compiler program to work?

        //__name __is a __adjective __noun_. __They are always __adverb __verb_.
        String ageAsString = console.readline("How old are you?  ");
        int age = Integer.parseInt(ageAsString);
        if (age < 13) {
        //Insert exit code
        int age = 12
        if (age < 13) {
          //Insert exit code
          console.printf("Sorry, you must be at least 13 to this program.\n");
          system.exit(0);
          }
        String name = console.readLine("Enter a name:  ");
        String adjective = console.readLine(Enter an adjective:  ");
        String noun = console.readLine("Enter a noun:  ");
        String adverb = console.readLine("Enter an adverb:  ");
        String verb = console.readLine("Enter a verb ending in -ing:  ");

        console.printf("Your TreeStory:\n----------------\n");
        console.printf("%s is a %s.  ", name, adjective, noun);
        console.printf("They are always %s %s.\n", adverb, verb);
