- True or False: Between method calls, the value of a local variable is preserved.Retail StoreSuppose you have been consulted by a retail shop around your area to build a simple calculator. The calculator must be able to perform arithmetic operations (+, -, *, /) on integers. The program receives an expression from the user. The expression is structured as follows: integer input followed by an operator and another integer input from user prior to displaying the final result. Write a Java application that can perform the above expression. Create a method that takes two parameters and performs an arithmetic operation on the passed values. Your final output should consist of the expression and the result.True or False: When passing multiple arguments to a method, the order in which the arguments are passed is not important.
