如何在java中从字符串中删除子字符串

Question

我需要预处理一个字符串并从中删除一些单词。我要找的是：-

private static final String[] stopWords = { "is", "on", "of", "with"};
String s1 = "Tiger is Mammal with sharp teeth";
System.out.println("s1 = " + s1);  // "Tiger is Mammal with sharp teeth"
s1.remove(stopWords);  //remove should remove 'is' and 'with'  from s1
System.out.println("s1 = " + s1); // "Tiger Mammal sharp teeth"

我对编程很陌生，所以请考虑一下。

您可以使用regular expression来实现这一点：

s1 = s1.replaceAll("\\b(is|on|of|with)\\b","");

这将删除单词，但在两侧保留空格，因此在此之后，您可能希望将双空格替换为单空格：

s1 = s1.replace("  "," ");
