In this article, we would like to show you how to replace last 2 characters in string in Java.

Quick solution:

String text = "ABC";
String replacement = "12";
String result = text.substring(0, text.length() - 2) + replacement;

System.out.println(result);  // A12

 

Practical example

In this example, we use substring() method to remove last 2 characters from the text string, then we add the replacement at their place.

public class Example {

    public static void main(String[] args) {
        String text = "ABC";
        String replacement = "12";
        String result = text.substring(0, text.length() - 2) + replacement;

        System.out.println("Original string: " + text);     // ABC
        System.out.println("Modified string: " + result);   // A12
    }
}

Output:

Original string: ABC
Modified string: A12

Note:

The replacement length doesn't have to be equal to 2. You can remove the last 2 characters from the end of the string and add any number of characters instead.
