Create a program called $`$MySecondProgram$.$java$`.$

$-(1)$ Define two String variables and provide any value that you want. Use Computer Science

$-(2)$ Define two numbers $($one of them must be a decimal number$).$ Use $4,2\mathrm{.}5$

$-(3)$ Define a variable called third that will hold the third character from the first String defined in $(1).$

What will be the data type of this variable?

$-(4)$ Define a variable called sum that will store the addition of the two numbers that you defined in $(2).$

$-(5)$ Define a variable called second that will contain the value of second String from $(1).$ The content of the second character must be in uppercase.

$-(6)$ Define a String variable called password that will be composed of the following characters:

a: the first character from the second String

b: the second character from the second String

c: the first number

d: the last character from the first String

e: the second number

f: a special character of your preference

The resulting password can be demonstrated by printing the variable password using the println$()$ function.
