A barbershop consists of a waiting room with n chairs and the barber room containing the barber chair. If there are no customers to be served, the barber goes to sleep. If a customer enters the barbershop and all chairs are occupied, then the customer leaves the shop. If the barber is busy but chairs are available, then the customer sits in one of the free chairs. If the barber is asleep, the customer wakes up the barber. Required:
Write a program to coordinate the barber and the customers. That is, write one procedure for the Barber process and one procedure for the customer process.)

Write a program to compute the ideal weight for both males and females in java. according to one study, the ideal weight for a female is 100 pounds plus 5 pounds for each inch in height over 5 feet. for example, the ideal weight for a female who is 5'3" would be 100 + 3*5 = 115 pounds. for a male, the ideal weight is 106 pounds plus 6 pounds for each inch in height over 5 feet. for example, the ideal weight for a male who is 5'3" would be 106 + 3*6 = 124 pounds. your program should ask the user to enter his/her height in feet and inches (both as integers—so a person 5'3" would enter the 5 and the 3). it should then compute and print both the ideal weight for a female and the ideal weight for a male. the general outline of your main function would be as follows: (1) declare your variables (think about what variables you need—you need to input two pieces of information, then you need some variables for your calculations (see the following steps) (2) get the input (height in feet and inches) from the user (3) compute the total number of inches of height (convert feet and inches to total inches (note: 1 foot equal 12 inches and hence 5 feet equal 60 inches. (4) compute the ideal weight for a female and the ideal weight for a male (5) print the answers.
