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

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

replaceAll("[\n\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\n\tText";       System.out.println("Original String with tabs, spaces and newline: \n"+originalStr);       originalStr = originalStr.replaceAll("[\n\t ]", "");       System.out.println("\nString 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 karthikeya Boyini Updated on: 2020-06-27T06:36:38+05:30
