Removing the last character from a string in Java

In this tutorial, we are going to learn about how to remove the last character from a string in Java.

Removing the last character

To remove the last character from a string, we can use the built-in substring() method by passing 0 as a first argument and string.length()-1 as the second argument in Java.

Here is an example, that removes the last character a from the greet string:

String greet = "helloa";
String result = greet.substring(0, greet.length()-1)
System.out.println(result);

Output:

hello

In the example above, we have passed 0, greet.length()-1 as arguments to the substring() method. so it begins the extraction at index position 0 and extracts before the last character position of a string.

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