Is it possible to replace multiple characters in a string with one? I saw some ways to do this with loops, but isnt it possible to do it easier?
For example:
input: /////Hello//this////////is///Java
output: /Hello/this/is/Java

Something like this:
String s = "/////Hello//this////////is///Java";
System.out.println(s.replaceAll("/+", "/"));

If i want to use the: String sepchar = java.io.File.separator; as the replacement it will give me the error: character to be escaped is missing. Do you have an idea why?

On my Linux
"/////Hello//this////////is///Java".replaceAll("/+", java.io.File.separator) works fine. However this separator is taken from FileSystem implementation that may be different on your system. What character it gives you? And what did you try?Michal Lonski
Ok, you probably use windows and get "\\" as separator character, quickfix is:
java.io.File.separator.replace("\\", "\\\\") to be used as replacement.This is a complete answer:
String Str = new String("Your string");
Set<Character> charsOfString = new HashSet<Character>();
int len = Str.length();
for(int i = 0 ; i < len ; i++)
charsOfString.add(Str.charAt(i));
for (Character c : charsOfString)
Str = Str.replaceAll(c + "+", c + "");
This will delete all duplicated characters of your string
