我需要将所有带有字符数4（或其他数字）的单词替换为“Test numbers test count gggg aaaaaa”。 最简单的方法是什么？

现在我尝试做了一些事情，但它无法正常工作：

SUPER

4 个答案:

答案 0 :(得分：3)

str.replaceAll("\\b\\w{4}\\b", "SUPER");应该有用，\\w表示字符; \\b表示字边界

答案 1 :(得分：2)

您可以使用此模式：\b\w{4}\b一个在开头和结尾都有单词边界的字母组

public static String rplcWordWithSize(int size, String sentence) {
    return sentence.replaceAll("\\b\\w{" + size + "}\\b", "SUPER");
}

使用示例：

public static void main(String argv[]) {
    String str = "Test numbers test count gggg aaaaaa";
    System.out.println(rplcWordWithSize(3, str));  //Test numbers test count gggg aaaaaa
    System.out.println(rplcWordWithSize(4, str));  //SUPER numbers SUPER count SUPER aaaaaa
    System.out.println(rplcWordWithSize(5, str));  //Test numbers test SUPER gggg aaaaaa
}

答案 2 :(得分：1)

请注意[aA-zZ]+ matches more than just letters，因为A-z范围与英文字母旁边的[, \, ], ^, _, `匹配。

如果您不希望更换＆＃34;单词＆＃34;例如1234或wrd5，只想替换自然语言非复合词，请使用以下两种解决方案之一。

这个可识别Unicode，\p{L}匹配任何Unicode字母和\b（字边界）＆＃34;支持＆＃34;由于Pattern.UNICODE_CHARACTER_CLASS修饰符嵌入标志(?U)：

，Unicode字边界 
s = s.replaceAll("(?U)\\b\\p{L}{4}\\b", "SUPER");

或者，如果您只打算使用ASCII：

s = s.replaceAll("\\b[a-zA-Z]{4}\\b", "SUPER");

请参阅online Java demo：

System.out.println("Test numbers test count gggg aaaaaa".replaceAll("\\b[a-zA-Z]{4}\\b", "SUPER"));
// => SUPER numbers SUPER count SUPER aaaaaa
System.out.println("Маша ела кашу".replaceAll("(?U)\\b\\p{L}{4}\\b", "SUPER")); 
// => SUPER ела SUPER

答案 3 :(得分：0)

试试这个：

Matcher m = p.matcher(myText);
String word = myText.substring(m.start(), m.end());

String[] words = word.Split(" ");
String newword = "";
for(String w : words){
if(w.length == myWord.length){
newword += "SUPER ";
}
else{
newword += w + " ";
}
}
Console.println(newword);

这是否直接来自短信，因此可能会出现一些小错误。
