Question

For accessing individual characters of a String in Java, we have String.charAt(2). Is there any inbuilt function to remove an individual character of a String in java?

Something like this:

if(String.charAt(1) == String.charAt(2){
   //I want to remove the individual character at index 2. 
}

Answer 1

You can also use the StringBuilder class which is mutable.

StringBuilder sb = new StringBuilder(inputString);

It has the method deleteCharAt(), along with many other mutator methods.

Just delete the characters that you need to delete and then get the result as follows:

String resultString = sb.toString();

This avoids creation of unnecessary string objects.
