我试图使用HashSet来确保我从.txt文件中读取的数据是唯一的.

以下是样本数据;

999990  bummer
999990  bummer
999990  bummer
999990  bummer
99999   bummer
999990  bummerr

        uniqueSet.add(new Term(Double.parseDouble(tokens[0]), tokens[1])); //add the term to set
    }
    else {
      rawTerms.close();
      throw new Exception("Invalid member length: "+ tokens.length);
    }           
}

allTerms = new ArrayList<>(uniqueSet); //Covert set into an ArrayList

使用番石榴的术语类;

public Term(double weight, String theTerm){
    this.weight = weight;
    this.theTerm = theTerm;
}


@Override
public boolean equals(final Object obj) {
    if …
