# Get the last 3 digits of a number in Java

In this tutorial, we are going to learn about how to get the last 3 digits of a number in Java.

Note: Strings are sequence of characters, where indexes are zero-based. The last character is in position 0, the second in 1, and index of a last character is `string.length()-1` etc.

## Get the last 3 digits of a number

To get the last 3 digits of a number, convert the number to a string and call the `substring()` method on it, by passing the `string.length()-2` as a argument.

The substring() method returns the last 3 character of a string then convert the result back to a number to get the last 2 digits.

Note: The string.length()-3 givens index of a third character from the end.

Here is an example:

``````int price = 421039;
String priceStr = Integer.toString(price);
int lastThreeIndex = priceStr.length()-3; // 3nd character index from last
int lastThreeDigits = Integer.parseInt(priceStr.substring(lastThreeIndex));

System.out.println(lastThreeDigits);``````

Output:

``039``

In the example above, on the first step we have converted the number to a string using the `Integer.toString()` method.

We have passed the `priceStr.length()-3` as argument to the substring() method, so it returns the last 3 characters.

The last step, we used the Integer.parseInt() method to convert it back to a number.

or You can get the last 3 digits of a number, by dividing the number by 1000 using modulo operator `%`.

Here is an example:

``````int price = 421039;
lastThreeDigits = price % 1000;

System.out.println(lastThreeDigits);``````
