ROGRAM Print the source code of this program plus the output of the following four executions: Execution 1: Input the weight as a negative number of ounces. Execution 2: Input the weight as 0ounces. Execution 3: Input the weight as 5 ounces. Execution 4: Input the woight as 42 ounces. Write three methods for this program assignment as follows .One method to read the required input values. A second method to perform the required calculations using the input values from the first function A third method to display the results of the second method. Speedy-Pants Delivery Inc. charges by weight for delivery of packages. The delivery charge for the first pound is S3.00 and S0.50 is added onto the charge for each additional four ounces. For example A package weighing more than 16 but at most 20 ounces costs $3.50 to deliver. A package weighing more than 20 but at most 24 ounces costs $4.00 to deliver. etc. Write a program that inputs the weight of a package in ounces, computes the charge fordelivery, and displays he screen. NOTE: One pound equal16 ounces. Note: (1) Use a double-valued method, getWeightInput, to prompt the user for input. (2) Use a double-valued method, computeDeliveryCharge, to compute the charge for delivery. (3) Use a void method, displayDeliveryCharge, to display the delivery charge
