Removing the first 3 characters from a string

What is the most efficient way to remove the first 3 characters of a string?

For example:

'apple' change to 'le'

'a cat' change to 'at'

' a b c'change to 'b c'

Just use substring: "apple".substring(3); will return le

Use the substring method of the String class :

String removeCurrency=amount.getText().toString().substring(3);
