    1. Suppose you are working in an airline company. Customers check baggage with various sizes and weights. Each piece of baggage has its own dimensions (length, width, height) as well as weight. You will write a Java program that allows the airline staff to input baggage dimensions and weight information. The computer will determine if the baggage is allowed to be checked in. If it is allowed, the system will then calculate the price based on the size and weight....
