Question

Write a method that returns a String that is just the first and last character of the given string Your return value should be only two characters long. You can assume that the given string will not be empty.​

Answer 1

Answer:

The method in Java is as follows:

public static String returnlen(String input){

   String output = ""+input.charAt(0)+input.charAt(input.length()-1);

   return output;

}

Explanation:

This defines the method

public static String returnlen(String input){

This concatenates the first and the last character of the input string

   String output = ""+input.charAt(0)+input.charAt(input.length()-1);

This returns the concatenated string

   return output;

}
