Remove newline, space and tab characters from a string in Java


To remove newline, space and tab characters from a string, replace them with empty as shown below.

replaceAll("[\
\t ]", "");

Above, the new line, tab, and space will get replaced with empty, since we have used replaceAll()

The following is the complete example.

Example

 Live Demo

public class Demo {
   public static void main(String[] args) {
      String originalStr = "Demo
\tText";       System.out.println("Original String with tabs, spaces and newline:
"+originalStr);       originalStr = originalStr.replaceAll("[\
\t ]", "");       System.out.println("
String after removing tabs, spaces and new line: "+originalStr);    } }

Output

Original String with tabs, spaces and newline:
Demo
Text
String after removing tabs, spaces and new line: DemoText
