用单词 "myWord" 替换所有出现的 {.?!"><',/\|@#$%^&*~`-_=+}

Question

例如：输入 String 是

Input =  "Hello there, How are you? Fine!! @xyz"

输出为

Output = "Hello there myWord How are you myWord Fine myWord myWord  myWord xyz"

我试过 Pattern class 和 Matcher class 但它只替换了一种模式和 str.replace(".","myWord");

Answer 1

你可以使用[^\w\s]

\s*[^\w\s]\s* :\s* 表示一个或多个 space

[^\w\s] : ^ 不捕获 \w 和 \s

\w 意思是 a-zA-Z0-9_

\s意思是space

    String s="Hello there, How are you? Fine!! @xyz";
    System.out.println(s.replaceAll("\s*[^\w\s]\s*", " myWord "));

输出：

Hello there myWord How are you myWord Fine myWord  myWord  myWord xyz

为了避免任何其他特殊字符，不应替换它们，然后只需将它们添加到此 [] 中，例如 \s*[^\w\s:;\[\]]\s*，正如@brso05

所指出的

演示

const regex = /\s*[^\w\s\]\[;]\s*/g;
const str = `Hello there, How are you? Fine!! ; @xyz []`;
const subst = ` myWord `;
const result = str.replace(regex, subst);
console.log(result);

Answer 2

你可以这样做：

String str = "Hello there, How are you? Fine!! @xyz";
    str = str.replaceAll("[\{\.\?!\"><',/\\\|@#$%^&\*~`\-_=+\}]", "myWord");
    System.out.println(str);

输出：

Hello theremyWord How are youmyWord FinemyWordmyWord myWordxyz

用单词 "myWord" 替换所有出现的 {.?!"><',/\|@#$%^&*~`-_=+}

Replace all the occurrence of {.?!"><',/\|@#$%^&*~`-_=+} with a word "myWord"

java

replace
