こんにちは、以下は私のJavaプログラムで、いくつかのストップワードを配列に保持し、これらのストップワードをテキストファイル内の単語と比較し、ストップワードではない単語について、単語の頻度を数えています。

String[] stopwords ={"a", "about", "above", "above", "across", "after", "afterwards", "again", "against", "all", "almost",

Scanner fip1=new Scanner(new File("c:/sample.txt"));

Map map = new TreeMap();

Integer ONE = new Integer(1);
while(fip1.hasNext()) {
    int flag=1;
    String s1=fip1.next();
    s1=s1.toLowerCase();
    for(int i=0;i<stopwords.length;i++) {
        if(s1.equals(stopwords[i])) {
            flag=0;
        }
    }
    if(flag!=0) {
        if (s1.length() > 0) {

        Integer frequency = (Integer) map.get(s1);
        if (frequency == null) {
            frequency = ONE;
        } else {
            int value = frequency.intValue();
            frequency = new Integer(value + 1);
        }
        map.put(s1, frequency);
        System.out.println(map);                  
        }                     
    }
}

私は次の出力を得ています

{contains=1}
{contains=1, java=1}
{contains=1, java=2}
{contains=1, java=2, related=1}
{contains=1, information=1, java=2, related=1}

しかし、私は次のo/pだけを取得したい

{contains=1, information=1, java=2, related=1}

これを行う方法を教えてください

ありがとう

while ループの外側でマップを印刷するだけです。

while ループから削除System.out.println(map);し、while ループの外側でマップを pring します

while(fip1.hasNext)ループの外でマップを印刷します。

while(fip1.hasNext) {
....
        map.put(s1, frequency);               
        }                     
    }
}
System.out.println(map);
