How can I split a string by two delimiters?

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}
