Remove Punctuation From String in Java

This tutorial introduces how to remove punctuation from a string in Java.

Punctuation is basically some special chars that are used to make a text grammatically correct. Some punctuation marks are comma(,), colon(:), question marks(?), etc. Let’s see some examples in Java.

Remove Punctuation From String Using the replaceAll() Method in Java

We can use a regex pattern in the replaceAll() method with the pattern as \\p{Punct} to remove all the punctuation from the string and get a string punctuation free. The regex pattern is \\p{Punct}, which means all the punctuation symbols. See the example below.

public class SimpleTesting {
	public static void main(String[] args){
		String str = "String - is a squence of chars:~!@#$%^&*(). Test.";
		System.out.println(str);
		String result = str.replaceAll("\\p{Punct}", "");
		System.out.println(result);
	}
}

Output:

String - is a squence of chars:~!@#$%^&*(). Test.
String  is a squence of chars Test
