Java - replace last 3 characters in string
0 points
In this article, we would like to show you how to replace last 3 characters in string in Java.
Quick solution:
xxxxxxxxxx1
String text = "ABCD";2
String replacement = "123";3
String result = text.substring(0, text.length() - 3) + replacement;4
5
System.out.println(result); // A123
In this example, we use substring() method to remove last 3 characters from the text string, then we add the replacement at their place.
xxxxxxxxxx1
public class Example {2
3
public static void main(String[] args) {4
String text = "ABCD";5
String replacement = "123";6
String result = text.substring(0, text.length() - 3) + replacement;7
8
System.out.println("Original string: " + text); // ABCD9
System.out.println("Modified string: " + result); // A12310
}11
}Output:
xxxxxxxxxx1
Original string: ABCD2
Modified string: A123Note:
The
replacementlength doesn't have to be equal to 3. You can remove the last 3 characters from the end of the string and add any number of characters instead.
