Java removes a small example of spaces, carriage returns, line breaks, and tabs in a string _java

Copy Code code as follows:

Import Java.util.regex.Matcher;
Import Java.util.regex.Pattern;

public class StringUtils {

    public static string Replaceblank (String str) {
        String dest = "";
        if (str!=null) {
             pattern p = pattern.compile ("\\s*|\t|\r|\n");
            Matcher m = p.matcher (str);
            dest = M.replaceall ("");
       }
        return dest;
   }
    public static void Main (string[] args) {
        System.out.println (Stringutils.replaceblank ("Just do it!"));
   }
   /*-----------------------------------

Stupid way: string s = "You want to remove the string";
. Remove Space: s = s.replace (' \\s ', ');
. Remove carriage return: s = s.replace (' \ n ', ');

This can also be removed from the space and carriage, others can do so.

Note: \ n carriage return (\u000a)
\ t Horizontal tab (\U0009)
\s Space (\u0008)
\ r line Wrap (\u000d) * *
