With these it helps String is Ticket-178(Good) Like this.. , Is this what you need?
code :
test1 = "Ticket-178(Good)"
test2 = "Ticket-178(Bad)"

def parse_ticket(str)
   str.match(/(\d+)\((\w+)\)/) do |match|
     return [match[1],match[2]]
 end
end

parse_ticket test1 # => ["178", "Good"]
parse_ticket test2 # => ["178", "Bad"]

To fix this issue I want to split a string in Javascript using split function into 2 parts. , You can use match instead of split:
code :
str='123&345&678&910';
splited = str.match(/^([^&]*?)&(.*)$/);
splited.shift();
console.log(splited);
["123", "345&678&910"]

should help you out I need to split strings containing basic mathematical expressions, such as: , Try splitting your data using
code :
yourString.split("(?<=[\\Q+-*()\\E/\\s])|(?=[\\Q+-*()\\E/\\s])(?<!^)"));
String[] tokens = " a+(ab-c1  )+12 "
        .split("(?<=[\\Q+-*()\\E/\\s])|(?=[\\Q+-*()\\E/\\s])(?<!^)");
for (String token :  tokens)
    System.out.println("\"" + token + "\"");
" "
"a"
"+"
"("
"ab"
"-"
"c1"
" "
" "
")"
"+"
"12"
" "

will be helpful for those in need I have String called "RamaSubbaReddyabcdaacacakkkoooahgafffgahgghsa". I want to know number of "a" characters available in the give String. As per my knowledge I found two ways to find the count. That are: 1) By using String.Split() 2) Linq Lambda Expression
code :
string str = "RamaSubbaReddyabcdaacacakkkoooahgafffgahgghsa";
int countA = str.Count(r => r == 'a');
string str = "RamaSubbaReddyabcdaacacakkkoooahgafffgahgghsa";
char searchChar = 'a';
int countA = str.Count(r => char.ToUpperInvariant(r) == char.ToUpperInvariant(searchChar));
string str = "RamaSubbaReddyabcdaacacakkkoooahgafffgahgghsa";
char searchChar = 'a';
char[] delimeters = new char[2];
delimeters[0] = char.ToLowerInvariant(searchChar);
delimeters[1] = char.ToUpperInvariant(searchChar);
var count = str.Split(delimeters).Length - 1;

How to split string for all fields in a Spark column and grab the length of the returned split string list?

will help you I'm currently attempting the grab the amount of services a specific IP is running, and the services are in a service column, stored as a StringType() in a Spark DataFrame and are separated via commas. How do I go about splitting the string (split is based on commas) in each field, then aggregating the length of the returned list for each field? , Using PySpark API:
code :
>>> df = spark.createDataFrame([("10.0.0.1", "session1,session2"), ("10.0.0.2", "session1,session3,session4")], ["ip", "session"])
>>> df.show(100, False)
+--------+--------------------------+
|ip      |session                   |
+--------+--------------------------+
|10.0.0.1|session1,session2         |
|10.0.0.2|session1,session3,session4|
+--------+--------------------------+

>>> from pyspark.sql.functions import *
>>> df = df.withColumn("count", size(split(col("session"), ",")))
>>> df.show(100, False)
+--------+--------------------------+-----+
|ip      |session                   |count|
+--------+--------------------------+-----+
|10.0.0.1|session1,session2         |2    |
|10.0.0.2|session1,session3,session4|3    |
+--------+--------------------------+-----+

may help you . Solution 1
Ok, I think you can do it in two steps, replace all non necessary characters with space for example and then split with space, your regex can look like like :
code :
[)(*+/^!@#%&,]|\\b-\\b
String[] tokens = function.replaceAll("[)(*+/^!@#%&,]|\\b-\\b", " ").split("\\s+");
Pattern.compile("\\b\\w+->\\w+\\b|\\b\\w+\\b")
        .matcher("round((TOTAL_QTY * 100) / SUM(ORDER_ITEMS->TOTAL_QTY) , 1)")
        .results()
        .map(MatchResult::group)
        .forEach(s -> System.out.println(String.format("\"%s\"", s)));
"round"
"TOTAL_QTY"
"100"
"SUM"
"ORDER_ITEMS->TOTAL_QTY"
"1"
