Java Algorithms How to - Split a string at every n-th character
Stream; import static java. You will see I am using a Linux box. I think you will find Scanner nextLine easiest to use. Dear Campbell Ritchie, Thank you very much for your effort to help me. Your nice work does not work on Windows, but finally, I found a solution. I had to change ZZ. Maybe it has something to do with translating the escapes in the command line arguments.
Thanks tiny ad, for helping me escape the terrible comfort of this chair. Boost this thread! How to sort an arraylist of multiple strings based on the highest value of the last column? Why are finals allowed for method-local classes??
Devious Experiments for a Truly Passive Greenhouse!We have a large array and we want to split it into chunks. So these are few of the methods to do it.
Return value: Returns a new Array, having the removed items. This method selects the elements starts from the given start argument, and ends at, but excluding, the given end argument. Return value: Returns a new Array, having the selected items. Example This example uses the slice method to split the array into chunks of array.
This method can be used repeatedly to split array of any size. Example This example uses the splice method to split the array into chunks of array. This method removes the items from the original array. If you like GeeksforGeeks and would like to contribute, you can also write an article using contribute.

In the first example, we simply assigned a string to a variable. In the second example, we used new String to create a string object and assign it to a variable. Most of the time you will be creating string primitives. While this concept is a bit challenging at first, you should be aware of the distinction between primitive and object.
The whitespace characters also have an index, at 3 and 7. Being able to access every character in a string gives us a number of ways to work with and manipulate strings. We can also use the charAt method to return the character using the index number as a parameter.
Alternatively, we can use indexOf to return the index number by the first instance of a character. For both of these methods, you can also search for multiple characters in the string. It will return the index number of the first character in the instance.
Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. As the title says, I've got a string and I want to split into segments of n characters. Building on the previous answers to this question; the following function will split a string str n-number size of characters. Above function is what I use for Base64 chunking.
It will create a line break ever 75 characters. I also tried to compare my solution to regexp one which was chosen as right answer. Tests are showing that both methods have similar performance, maybe on first look regexp solution is little bit faster, but judge it Yourself. Here's a way to do it without regular expressions or explicit loops, although it's stretching the definition of a one liner a bit:. It works by splitting the string into an array of individual characters, then using Array.
Normally reduce would return a single value, but in this case the single value happens to be an array, and as we pass over each character we append it to the last item in that array. Once the last item in the array reaches the target length, we append a new array item.
Pre-calculating the end value as part of the for loop is faster than doing the inline math inside substring. I've tested it in both Firefox and Chrome and they both show speedup. You can try it here. Learn more. How can I split a string into segments of n characters?

David Tang David Tang This is technically the better answer as it will grab all the text from a string that's not evenly divisible by 3 it will grab the last 2 or 1 characters. You may want to start a new cycle on every line. If you really do have newlines, they probably indicate some type of transition.
Is it possible to have a variable in the place of number 3? If you didn't want to use a regular expression It's more readable than concatenating a regexp string. This is more than 10x faster than the regex option, so I would go with this inside of a function jsbench. My previous statement applies to Chromium also, I was too late with editing the previous comment hence the new one.

Active Oldest Votes. TrevorRudolph It only does exactly what you tell it. The above answer is really only just a for loop but expressed pythonically. Also, if you need to remember a "simplistic" answer, there are at least hundreds of thousands of ways to remember them: starring the page on stackoverflow; copying and then pasting into an email; keeping a "helpful" file with stuff you want to remember; simply using a modern search engine whenever you need something; using bookmarks in probably every web browser; etc.
On second though, it appears as though you are serious. I actually hope you are serious since it really isn't convoluted. Ironically, trying to use words in a way that will not have hidden meaning, will often result in convoluted sentences.
This is by far the best answer here and deserves to be on top. One could even write '.For instance, if a program asks for your full name, including middle initial, it will first need to split that input into three separate strings before it can work with your individual first, middle and last name. This is achieved using the String split method. In its most basic form, String split takes a single argument: the field delimiter as a string.
This delimiter will be removed from the output and an array of strings split on the delimiter will be returned. So, in the following example, assuming the user input their name correctly, you should receive a three-element Array from the split.
If we run this program and enter a name, we'll get some expected results. Also, note that name. The name variable will be an Arrayand those two method calls will be equivalent to name and name[-1] respectively. However, that's the only special case when you pass a String as the first argument.
Regular Expression Delimiters. You can also pass a regular expression as the first argument. Here, String split becomes a bit more flexible. We can also make our little name splitting code a bit smarter.
We don't want the period at the end of the middle initial. We know it's a middle initial, and the database won't want a period there, so we can remove it while we split. When String split matches a regular expression, it does the same exact thing as if it had just matched a string delimiter: it takes it out of the output and splits it at that point. Ruby is not really big on "special variables" that you might find in languages like Perl, but String split does use one you need to be aware of.
It's a global, something you don't often see in Ruby, so if you change it, it might affect other parts of the code—just be sure to change it back when finished. However, all this variable does is act as the default value for the first argument to String split.
Split string by every 2 characters
By default, this variable seems to be set to nil. However, if String split 's first argument is nilit will replace it with a single space string. If the delimiter passed to String split is a zero-length string or regular expression, then String split will act a bit differently. It will remove nothing at all from the original string and split on every character. This essentially turns the string into an array of equal length containing only one-character strings, one for each character in the string.
This can be useful for iterating over the string and was used in pre However, if what you really want to do is iterate over a string, and you're using 1. So back to our name parsing example, what if someone has a space in their last name? For instance, Dutch surnames can often begin with "van" meaning "of" or "from". We only really want a 3-element arrayso we can use the second argument to String split that we have so far ignored. The second argument is expected to be a Fixnum.
If this argument is positive, at most, that many elements will be filled in the array. So in our case, we would want to pass 3 for this argument. However, if this argument is negative any negative numberthen there will be no limit on the number of elements in the output array and any trailing delimiters will appear as zero-length strings at the end of the array.
