我正在尝试在字符串“zach”中搜索停用词 THE”、“BE”、“TO”、“OF”、“AND”、“A”、“IN”、“THAT”、“I ”、“IT”、“ON”、“IN”、“但是”、“IS”、“WIT​​H”。

我不确定字符串搜索方法是否有效，或者是否有更好的方法来做到这一点。

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);

        }
    }
}

假设您使用的是 Java 8+，您可以使用 Stream.noneMatch喜欢

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

并且，\\s+ 匹配正则表达式中的一个(或多个)空格。
