How to get last n characters of a string in Java

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

Consider, we have a following string:

String name = "piano";

Now, we want to get the last 3 three characters "ano" from the above string.

Getting the last n characters

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

The String.length() method returns the total number of characters in a string, n is the number of characters we need to get from a string.

Here is an example, that gets the last 3 characters of a string:

String name = "piano";

String lastThree = name.substring(name.length()-3);

System.out.println(lastThree);

Output:

"ano"

Note: The extraction begins at index 2, and extract the rest of the string.

Similarly, we can also get the last 4 characters of a string like this:

String name = "piano";

String lastFour = name.substring(name.length()-4);

System.out.println(lastFour);

Output:

"iano"
