Java布尔值始终为true

我在使用学校的Java代码时遇到了麻烦-我试图创建一个采用布尔值的构造函数，然后在以后使用它，但是出于某种原因，它始终是正确的.有人可以告诉我我在做什么错吗?

I'm having trouble with my school Java code - I'm trying to create a constructor that takes a boolean value, and then uses it later, but for some reason it's always true. Could anyone tell me what I'm doing wrong?

我正在发布我的整个代码，我想稍微编辑一下可以使我的问题更加清楚，但是看来这只会造成混乱.

I'm posting my entire code, I thought redacting it a little would make my problem clearer, but it seems it only created confusion.

        import java.util.*;

    // TODO Auto-generated method stub

    class FunnyString{
        private boolean ascii;

        private char separator;


        public FunnyString (String slowo, char separator, boolean ascii){
            this.slowo=slowo;
            this.separator=separator;
            this.ascii=ascii;

        }
        public FunnyString (String slowo, char separator){
            this(slowo, separator, false);
        }
        public FunnyString (String slowo, boolean ascii){
            this(slowo,'-', ascii);

            }while (licznik!=dlugosc);
            wynik+="\n";

            return wynik;
        }
    }
          FunnyString w1=new FunnyString("Kaktus");
          FunnyString w2=new FunnyString("Eukaliptus",'*');  
          FunnyString w3=new FunnyString("Yuka",true);

          System.out.println(w1);

          System.out.println(w2);

          System.out.println(w3);

          w1.setAscii(true);
          w1.setChar('*');
          System.out.println(w1);

          w3.setAscii(false);
          w3.setChar('!');
          System.out.println(w3);
