Answer to Question #246181 in Java | JSP | JSF for Aubrey Eso Jozela

Question

Code a method problemlab(). This method has no parameters and is void. This method displays all computer labs that have less working computers that number of seats. Use the methods problemVenue() and show() coded in question 2. Expected output (take note of headings and other formatting): Problem computer labs Building name: Engineering Venue number: 1.35 Number of seats: 50 Number of working computers: 30 ------------------------- Building name: Engineering Venue number: 1.24 Number of seats: 40 Number of working computers: 35 -------------------------
