Java - remove prefix from string
0 points
In this article, we would like to show you how to remove prefix from string in Java.
Quick solution:
xxxxxxxxxx1
String text = "ABCD";2
3
// replace "AB" only if it is at the beginning4
String result1 = text.replaceAll("^AB","");5
6
// remove the first two characters7
String result2 = text.substring(2);8
9
10
System.out.println(result1); // CD11
System.out.println(result2); // CD
In this example, we use replaceAll() method with regex to replace the first two letters (AB) with an empty string.
xxxxxxxxxx1
public class Example {2
3
public static void main(String[] args) {4
String text = "ABCD";5
6
// replace the AB only at the beginning of the string7
String result = text.replaceAll("^AB", "");8
9
System.out.println(result); // CD10
}11
}In this example, we use substring() method to remove first two letters from the text.
