Delete Last and First Char in a String

Question

I just wanted to ask how to remove the first and the last char form a String. The easiest and best looking would be great :)

Answer 1

String s = "Hello World!";
s = s.substring(1, s.length() - 1); // --> "ello World"

Answer 2

Use the substring() method:

String newString = oldString.substring(1, oldString.length() -1);

This skips the first char and substrings down to the end minus 1.

Answer 3

You can take advatage of String.substring() method:

public String removeFirstAndLastChar(String s)
{
   String withoutFirstChar = s.substring(1);

   return withoutFirstChar.substring(withoutFirstChar.length() - 1);
}

or shorter way:

public String removeFirstAndLastChar(String s)
{
   return s.substring(1, s.length() - 1);
}

Answer 4
