This way we can correctly process (and display) any Unicode symbol: IntStream intStream1 = dePoints() Supplementary characters are represented by Unicode surrogate pairs and will be merged into a single codepoint. The advantage of using this API is that Unicode supplementary characters can be handled effectively. Conversion Using codePoints()Īlternatively, we can use the codePoints() method to get an instance of IntStream from a String. However, if we're to display the characters for reading, we need to convert the integers to the human-friendly Character form: Stream characterStream = testString.chars() This can lead to some minor performance gains, as there will be no need to box each integer into a Character object.
It's possible to work with the integer representation of the characters without converting them to their Character equivalent. IntStream intStream = testString.chars() Simply put, IntStream contains an integer representation of the characters from the String object: String testString = "String" This simple API returns an instance of Int Stream from the input String. The String API has a new method – chars() – with which we can obtain an instance of S tream from a String object.
JAVA STRING TO CODEPOINTS HOW TO
In this quick article, we'll see how to convert a String to a Stream of single characters. If you want to read more about it, have a look at this article. Java 8 introduced the Stream API, with functional-like operations for processing sequences.
