美好的一天,我有Strings
:
"bus-nr-7b-Station-Yellow-Street",
"bus-nr-8-Station-Lewis-Street",
"train-nr-9-Station-Yield-Street",
"bus-nr-10-Station-Harrow",
"train-nr-10a-Station-Booki",
"train-nr-11-Station-Horope",
"bus-nr-12-Station-Erstin",
"bus-nr-13-Station-Green-Street",
"train-nr-13ab-Station-Final-Station",
最后,我想:
"B:7b",
"B:8",
"T:9",
"B:10",
"T:10a",
"T:11",
"B:12",
"B:13",
"T:13ab",
因此,我想用
-
或B:
替换第二个T:
之前的所有内容,并删除第三个-
之后的所有内容。我如何使用正则表达式来实现呢? 最佳答案
在您的情况下,不使用正则表达式会更快:
String foo = "bus-nr-7b-Station-Yellow-Street";
String[] parts = foo.split("-");
String result = Character.toUpperCase(foo.charAt(0)) + ":" + parts[2];
关于java - 正则表达式:删除第二个“-”之前和之后的所有内容,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/34745450/
