Remove the last 2 characters of a string in Java

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

Consider, we have a following string:

String name = "Romeoro";

Now, we want to remove the last 2 characters "ro" from the above string.

Remove the last 2 characters

To remove the last 2 characters of a string in Java, we can use the built-in substring() method by passing 0, String.length()-2 as an argument to it.

The String.length()-2 method removes the last 2 characters from a string.

Here is an example:

String name = "Romeoro";
String result = name.substring(0, name.length()-2);

System.out.println(result);

Output:

"Romeo"

In the example above, we have pass the 0, name.length()-2 as an arguments to the substring() method.So, the extraction begins at index 0, and ends before the name.length()-2 that is index 5.

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