Remove the first 2 characters of a string in Java

In this tutorial, we are going to learn about how to remove the first 2 characters of a string in Java.

Remove the first 2 characters

To remove the first 2 characters of a string, we can use the built-in substring() method in Java.

Here is an example:

String str = "12Hello";
String result = str.substring(2);
System.out.println(result);

Output:

"Hello"

In the example above, we have passed 2 as argument to the substring() method. so it begins the extraction at index position 2 and extracts to the end of a string.

Syntax of substring() method

 substring(startindex, stopindex)

It begins the extraction at startIndex and goes upto the stopindex-1, if we don’t provide the endIndex it begins the extraction at specified index extracts upto to the end of a string.

The substring() method doesn’t mutates the original string, instead of it creates a new one with the extracted characters.
