I was trying to split an arithmetic expression (eg "1+2+10+15") on the plus signs. However, I didn't manage to write the appropriate regular expression. I thought this would work:
expression.split("\\+"); but it doesn't. Do you know the correct solution?

To split a string by special characters, call the split() method on the string, passing it a regular expression that matches any of the special characters as a parameter. The method will split the string on each occurrence of a special character and return an array containing the results. Copied!
split("(? =\"[^\"]. *\")");
split("-"); We can simply use a character/substring instead of an actual regular expression. Of course, there are certain special characters in regex which we need to keep in mind, and escape them in case we want their literal value. Once the string is split, the result is returned as an array of Strings.
To split a string with dot, use the split() method in Java. str. split("[.]", 0);
It does. However split(...) returns an array, it does not "transform" your String into a String[]. Try this:
String expression = "1+2+10+1"; String[] tokens = expression.split("\\+"); this way
expression.split("[+]"); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
