Methods of StringBuilder class

The StringBuilder class can be used to create mutable strings. The methods defined in the StringBuilder class are widely used to manipulate and concatenate strings. It is a non-synchronized class which has public methods that can be accessed by multiple threads. It is not thread-safe.

Question

A. Complete the method named outsideIn3().
The method has one input: a String str that is
at least 3 characters long and of odd length.
The output of the method is a new String where
the middle character has been removed and placed
both at the beginning and end.
Examples:
outsideIn3("Cartons") returns "tCaronst" // t removed and placed at both
outsideIn3("Hip") returns "iHpi" //i removed placed at both ends.
outsideIn3("Barbara Ann") returns "rBarbaa Annr" //2ndr removed
@param str the String to process
@return a new String as described above.
*/
public String outsideIn3(String str)
// Complete the method here

B. Complete the method named alarmClock();
36
You are given a day of the week,
with Sun = 0, Mon
and a boolean indicating if you are on vacation.
Your method should return a String of the form
"7:00" indicating when the alarm clock should ring.
On weekdays, the alarm should be "7:00" and on
the weekend it should be "10:00". Unless you are
on vacation-then on weekdays it should be "10:00"
and weekends it should be "off".

In Programming When you work with text, sometimes you need to determine if a given string starts with or ends with certain characters. You can use two string methods to solve this problem: .startswith() and .endswith()?
PART B: WITHOUT ENDSGiven a string str, print out the string without the first and last char. Assume the string length is at least 2.Methods to use: substring(), length()Testing cases:Hello => ell java => av coding => odin code => od ab => (empty string)Chocolate! => hocolate kitten => itte woohoo => ooho
Return the smallest number of steps it takes to convert a string entirely into uppercase or entirely into lower case, whichever takes the fewest number of steps. A step consists of changing one character from lower to upper case, or vice versa. Examples stepsToConvert("abC") → 1 // "abc" converted to "abc" in 1 step steps ToConvert("abCBA") → 2 // "abCBA" converted to "ABCBA" in 2 steps stepsToConvert("aba") → 0 steps ToConvert("abaCCC") -3

Q1: Write a program that asks the user to enter their first name and their last name,separated by a space. Break the input string up into two strings, one containing thefirst name and one containing the last name. You can do that by using the indexOf()subroutine to find the position of the space, and then using substring() to extracteach of the two names. Also output the number of characters in each name andoutput the user’s initials. (The initials are the first letter of the first name togetherwith the first letter of the last name.) A sample run of the program should looksomething like this:Please enter your first name and last name, separated bya space.? Mary SmithYour first name is Mary, which has 4 charactersYour last name is Smith, which has 5 charactersYour initials are MS
