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