Is there a native way to sort a String by its contents in java? E.g.
String s = \"edcba\" -> \"abcde\"
In Java 8 it can be done with:
String s = "edcba".chars()
.sorted()
.collect(StringBuilder::new, StringBuilder::appendCodePoint, StringBuilder::append)
.toString();
A slightly shorter alternative that works with a Stream of Strings of length one (each character in the unsorted String is converted into a String in the Stream) is:
String sorted =
Stream.of("edcba".split(""))
.sorted()
.collect(Collectors.joining());
