字符串替换正则表达式条件

Question

我有一条短信

Hello everyone, my name is Ke-

vin, I was born in Indonesia 20-

01-1990. Nice to meet you.

那么如何将文本替换为

Hello everyone, my name is Kevin, I was born in Indonesia 20-01-1990. Nice to meet you.

我试过使用 String string = string.replace("-\n" , "");

Hello everyone, my name is Kevin, I was born in Indonesia 2001-1990. Nice to meet you.

那么如何在替换字符串中放入不同的大小写呢？在“-”之前的字母和数字之间。

Answer 1

当连字符前面有数字时，您可以使用 capturing group 来匹配数字和连字符，并使用 </code> 替换：</p> <pre><code>(?:(\d-)|-)

捕获一个数字后跟一个连字符
或匹配连字符（未捕获）

代码

String string = "Hello everyone, my name is Ke-\nvin, I was born in Indonesia 20-\n01-1990. Nice to meet you.";
String result = string.replaceAll("(?:(\d-)|-)\n+" , "");

System.out.println(result);

输出

Hello everyone, my name is Kevin, I was born in Indonesia 20-01-1990. Nice to meet you.

Answer 2

字符串结果 = string.replaceAll("-","").replaceAll("\r\n", "");
