I know that you can split your string using myString.split("something"). But I do not know how I can split a string by two delimiters.
Example:
mySring = "abc==abc++abc==bc++abc";I need something like this:
myString.split("==|++")What is its regularExpression?

Use this :
myString.split("(==)|(\\+\\+)")How I would do it if I had to split using two substrings:
String mainString = "This is a dummy string with both_spaces_and_underscores!"
String delimiter1 = " ";
String delimiter2 = "_";
mainString = mainString.replaceAll(delimiter2, delimiter1);
String[] split_string = mainString.split(delimiter1);Replace all instances of second delimiter with first and split with first.
Note: using replaceAll allows you to use regexp for delimiter2. So, you should actually replace all matches of delimiter2 with some string that matches delimiter1's regexp.
You can use this
mySring = "abc==abc++abc==bc++abc"; String[] splitString = myString.split("\\W+");Regular expression \W+ ---> it will split the string based upon non-word character.
Try this
String str = "aa==bb++cc";
String[] split = str.split("={2}|\\+{2}");
System.out.println(Arrays.toString(split));The answer is an array of
[aa, bb, cc]The {2} matches two characters of the proceding character. That is either = or + (escaped) The | matches either side
I am escaping the \ in java so the regex is actually ={2}|\+{2}
