Java拆分和替换

Question

我有以下字符串

String path = "(tags:homepage).(tags:project mindshare).(tags:5.5.x).(tags:project 5.x)";

我使用了以下代码，

String delims = "\\.";

String[] tokens = path.split(delims);
int tokenCount = tokens.length;
for (int j = 0; j < tokenCount; j++) {
    System.out.println("Split Output: "+ tokens[j]);
}

当前输出为

Split Output: (tags:homepage)
Split Output: (tags:project mindshare)
Split Output: (tags:5
Split Output: 5
Split Output: x)
Split Output: (tags:project 5
Split Output: x)

最终目标是将这个字符串转换为

String newpath = "(tags:homepage)(tags:project mindshare)(tags:5.5.x)(tags:project 5.x)";

Answer 1

您可以使用正向回顾来实现这一点:

String path = "(tags:homepage).(tags:project mindshare).(tags:5.5.x).(tags:project 5.x)";
String newPath = path.replaceAll("(?<=\\))\\.", ""); // look for periods preceeded by `)`
System.out.println(newPath);

操作:

(tags:homepage)(tags:project mindshare)(tags:5.5.x)(tags:project 5.x)
