To sort a String in Java, first get characters with toCharArray, then sort them with Arrays.sort, finally make a new String from them.

Here's how you do it:

String string = "Hello World!";
char[] characters = string.toCharArray();
java.util.Arrays.sort(characters);
String sortedString = new String(characters);

System.out.println(sortedString); // !HWdellloor
