Java - remove first 2 characters from string
0 points
In this article, we would like to show you how to remove the first 2 characters from the string in Java.
Quick solution:
xxxxxxxxxx1
String text = "ABCD";2
3
String result = text.substring(2);4
5
System.out.println(result); // CD
In this example, we use String substring() method to create a new result substring from the text string without the first 2 characters.
Syntax:
xxxxxxxxxx1
substring(int startIndex, int endIndex);Note:
By default
endIndexis the end of the string, so we don't need to specify it.
Practical example:
xxxxxxxxxx1
public class Example {2
3
public static void main(String[] args) {4
String text = "ABCD";5
6
String result = text.substring(2);7
8
System.out.println(result); // CD9
}10
}Output:
xxxxxxxxxx1
CDIn this example, we create sb StringBuilder object from the text string, then we use delete() method on the sb to delete the first 2 characters.
Syntax:
xxxxxxxxxx1
delete(int startIndex, int endIndex);Practical example:
xxxxxxxxxx1
public class Example {2
3
public static void main(String[] args) {4
String text = "ABCD";5
6
// Create StringBuilder object7
StringBuilder sb = new StringBuilder(text);8
9
// Remove first 2 characters10
sb.delete(0, 2);11
12
System.out.println(sb);13
}14
}Output:
xxxxxxxxxx1
CDIn this example, we create sb StringBuffer object from the text string, then we use delete() method on the sb to delete the first 2 characters.
Syntax:
xxxxxxxxxx1
delete(int startIndex, int endIndex);Practical example:
xxxxxxxxxx1
public class Example {2
3
public static void main(String[] args) {4
String text = "ABCD";5
6
// Create StringBuffer object7
StringBuffer sb = new StringBuffer(text);8
9
// Remove first 2 characters10
sb.delete(0, 2);11
12
System.out.println(sb);13
}14
}Output:
xxxxxxxxxx1
