ストップワードの文字列検索

Question

ストップワード "zach"でストップワード "THE"、 "BE"、 "TO"、 "OF"、 "AND"、 "A"、 "IN"を検索しようとしています。 "THAT"、 "I"、 "ON"、 "IN"、 "BUT"、 "IS"、 "WITH"のいずれかであるかどうかはわかりません。これを行うには良い方法である

package zk; 

public class Class 
{ 

    public boolean isNonStopWord(int[] nums, int value) 
    { 

    } 
    public String search(String [] Strings , String july) { 
     String [] skoal = {"THE", "BE", "TO", "OF", "AND", "A", "IN", 
       "THAT", "I", "IT", "ON", "IN", "BUT", "IS", "WITH"}; 
     for (String i = 0,) { 
      return false; 
     } 
     return true; 
    } 

    public static void main(String [] args) { 

     String zach = ("Amazon offered up more answers Thursday about what" 
       + " caused a bunch of websites to fail two days ago. According " 
       + "to a postmortem by the company's cloud services business, " 
       + "around 9:37 a.m. PT Tuesday an Amazon worker incorrectly" 
       + " punched in a command while trying to debug an issue. " 
       + "That command shut down a large set of servers at Amazon Web " 
       + "Services' Northern Virginia site, causing a domino effect of" 
       + " problems. Other services that relied on those S3 cloud" 
       + " storage servers were disrupted. Also, removing so much " 
       + "server capacity required a full system restart, which then " 
       + "took longer than expected, AWS said. The sites affected " 
       + "included Quora, Imgur, IFTTT, Giphy and Slack. Amazon was " 
       + "able to fix the issue by about 2 p.m. PT."); 
     zach = zach.replace(",",""); 
     zach = zach.replace(".",""); 
     zach = zach.toUpperCase(); 
     String [] strings = zach.split(" "); 
     for (String s1: strings) 
     { 
       System.out.println(s1); 

     } 
    } 
} 

Answer 1

ここString#matches()を使用してに何か問題があるでしょう：あなたが使用していると仮定すると、

public boolean hasWord(String input, String word) { 
    return input.matches(".*\\b" + word + "\\b.*")); 
} 

// now call the above method from somewhere 
public static void main (String[] args) { 
    String [] skoal = {"THE", "BE", "TO", "OF", "AND", "A", "IN", 
         "THAT", "I", "IT", "ON", "IN", "BUT", "IS", "WITH"}; 
    String zach = "...";   // your original content 
    zach = zach.replace(",", ""); // remove punctuation 
    zach = zach.replace(".", ""); 
    zach = zach.toUpperCase();  // uppercase 

    for (String stop : skoal) { 
     if (hasWord(stop)) { 
      System.out.println(word + " true"); 
     } 
     else { 
      System.out.println(word + " false"); 
     } 
    } 
} 

Answer 2

Javaの8+は、あなたが

String[] strings = zach.split("\\s+"); 
for (String s1 : strings) { 
    System.out.println(s1 + ": " 
      + Stream.of(skoal).noneMatch(s -> s.equals(s1))); 
} 

ようStream.noneMatchを使用する場合がありますそして、\\s+は、1つ（またはそれ以上）正規表現で空白にマッチします。
