Sam Towne CS1050 Midterm project Computer Part Builder Definition of program: Computer builder program that helps user create desktop and laptop. By prompting user to pic specifications for each design. Desired output: display Desktop and or laptop Specifications and price. Based off what the user picks Process. . input user name . input user choice For desktop Enter brand Enter case type Enter price Enter the cpu brand Enter cpu price Enter cpu speed Enter price Enter hard disk capacity Enter price Enter monitor size
Enter price Create desktop Display desktop properties End For laptop repeated process but exclude mini tower Psedocode: import java.text.DecimalFormat; import java.util.Scanner; // Main class public class ComputerBuilder
