Create a class called Cal and create a main method inside it.
Create a variable called firstNumber which will always be an integer.
Create a variable called secondNumber which will always be an integer.
Declare a Scanner called myScanner that will take in input from the user. Do NOT instantiate

multiple Scanners in Calculator.

Print to the console “Enter your first number: ”
Read the value inputted by the user and assign it to You should use nextInt()

to do this.

Print to the console “Enter your second number: ”
Read the value inputted by the user and assign it to You should use nextInt()

to do this.

Print out “Sum is ” followed by the sum of the two numbers

(firstNumber + secondNumber)

Printout“Differenceis”followed by the difference of the two numbers

(firstNumber – secondNumber)

Printout“Productis”followed by the product of the two numbers

(firstNumber * secondNumber)

Printout“Quotientis”followed by the quotient of the two numbers

(firstNumber / secondNumber).
The result should be displayed as a decimal regardless of whether the quotient is a real or number (e.g. print 2.5 for 5/2 and print 4.0 for 4/2). In order to do this, you will need to use casting to force floating point division.
