How can I split a string by 2 characters with shifting.
For example;
My string is = todayiscold
My target is: "to","od","da","ay","yi","is","sc","co","ol","ld"
but with this code:
Arrays.toString("todayiscold".split("(?<=\\G.{2})")));
I get: `"to","da","yi","co","ld"
anybody helps?

Create an array of characters from the input string. Traverse the String array from the start (index 0) to end (n-1, where n is the length of an array). Perform the shift operation on each and every character of an array. Convert modified array of characters to string and return it.
To split a string by multiple spaces, call the split() method, passing it a regular expression, e.g. str. trim(). split(/\s+/) . The regular expression will split the string on one or more spaces and return an array containing the substrings.
Q #4) How to split a string in Java without delimiter or How to split each character in Java? Answer: You just have to pass (“”) in the regEx section of the Java Split() method. This will split the entire String into individual characters.
Try this:
String e = "example";
for (int i = 0; i < e.length() - 1; i++) {
System.out.println(e.substring(i, i+2));
}
Use a loop:
String test = "abcdefgh";
List<String> list = new ArrayList<String>();
for(int i = 0; i < test.length() - 1; i++)
{
list.add(test.substring(i, i + 2));
}
