英文:
Split string in 3 blocks (Text - Number - Other characters) if possible
问题
List<String> AllAddress = Arrays.asList("Karbwqeaf 11D", "Jablunkovska 21/2", "Tastoor Nstraat 43", "Schzelkjedow", "Heajsd 3/5/7 m 344", "Lasdasdt seavees 3., 729. tasdasd F 2.", "ul. Pasydufasdfa 73k/120");for (String Address : AllAddress) {String block1 = "";String block2 = "";String block3 = "";Pattern pattern = Pattern.compile("([A-Za-z]+)\\s(\\d+)(.*)");Matcher matcher = pattern.matcher(Address);if (matcher.matches()) {block1 = matcher.group(1);block2 = matcher.group(2);block3 = matcher.group(3);System.out.println("Block1: " + block1);System.out.println("Block2: " + block2);System.out.println("Block3: " + block3);}}
英文:
I need to divide a string into 3 blocks at most
- The first block is only for letters
- The second only numbers
- The third the remainder
Examples:
Karbwqeaf 11DJablunkovska 21/2Tastoor Nstraat 43SchzelkjedowHeajsd 3/5/7 m 344Lasdasdt seavees 3., 729. tasdasd F 2.ul. Pasydufasdfa 73k/120
I need to split like this:
Block1: KarbwqeafBlock2: 11Block3: DBlock1: JablunkovskaBlock2: 21Block3: /2Block1: Tastoor NstraatBlock2: 43Block3:Block1: SchzelkjedowBlock2:Block3:Block1: HeajsdBlock2: 3Block3: /5/7 m 344Block1: Lasdasdt seavees 3Block2: 3Block3: ., 729. tasdasd F 2.Block1: ul. PasydufasdfaBlock2: 73Block3: k/120
Below my code, but I don't know how to do it so that all my requirements are met. Any idea?
List<String> AllAddress = Arrays.asList("Karbwqeaf 11D", "Jablunkovska 21/2", "Tastoor Nstraat 43", "Schzelkjedow", "Heajsd 3/5/7 m 344", "Lasdasdt seavees 3., 729. tasdasd F 2.", "ul. Pasydufasdfa 73k/120");for (String Address : AllAddress) {String block1 = "";String block2 = "";String block3 = "";Pattern pattern = Pattern.compile("(.+)\\s(\\d)(.*)");Matcher matcher = pattern.matcher(Address);if(matcher.matches()) {block1 = matcher.group(1);block2 = matcher.group(2);block3 = matcher.group(3);System.out.println("block1 = " + block1);System.out.println("block2 = " + block2);System.out.println("block3 = " + block3);}}

你可以使用3个捕获组，其中第二个组匹配1个或多个数字，第三个组匹配任意字符0次或多次。
^([^\d\r\n]+)(?:\h+(\d+)(.*))?$
解释
^字符串的开始(捕获组 1[^\d\r\n]+匹配除换行符或数字之外的任意字符
)关闭 捕获组 1(?:非捕获组\h+匹配1个或多个水平空白字符(\d+)(.*)在捕获组 2中捕获1个或多个数字，在捕获组 3中捕获0个或多个任意字符
)?关闭非捕获组，并使其变为可选$字符串的结尾
英文:
You can use 3 capturing groups, where the second group matches 1 or more digits and the 3rd group matches any character 0+ times.
^([^\d\r\n]+)(?:\h+(\d+)(.*))?$
Explanation
^Start of string(Capture group 1[^\d\r\n]+Match any char except a newline or digit
)Close group 1(?:Non capture group\h+Match 1+ horizontal whitespace chars(\d+)(.*)Capture 1 or more digits in group 2 and capture 0 or more times any character in group 3
)?Close the non capture group and make it optional$End of string
