Remove the last 3 characters of a string in Java

In this tutorial, we are going to learn about how to remove the last 3 characters of a string in Java.

Consider, we have a following string:

String name = "Romeoro";

Now, we want to remove the last 3 characters "oro" from the above string.

Remove the last 3 characters

To remove the last 3 characters of a string in Java, we can use the built-in substring() method by passing 0, String.length()-3 as an argument to it.

The String.length()-3 method removes the last 3 characters from a string.

Here is an example:

String name = "Romeoro";
String result = name.substring(0, name.length()-3);

System.out.println(result);

Output:

"Rome"

In the example above, we have pass the 0, name.length()-3 as an arguments to the substring() method.So, the extraction begins at index 0, and ends before the name.length()-3 that is index 4.

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