如何在java中从字符串中删除子字符串[重复]

Question

我需要对一个字符串进行预处理，并从中移除一些单词。我要找的东西是这样的：-

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"

我是新的编程，所以请考虑。

您可以使用正则表达式进行此操作：

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

这将删除单词，但保留两边的空格，因此在此之后，您可能需要将双空格替换为单行空格：

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