Question

Use Java programing

Write a program to display information about schools in North Carolina that offer a BS in Computer Science. The data file "NCuniversity Data dat" contains the following information on each line: BS in CS Instate cost Out of state cost int int int double fraction of students who return after first year String name of the school 0-no, 1-yes, 2-online only Expected annual cost for an in-state student Expected annual cost for an out of state student retention name You will probably want to read the school name using the nextLine () method. You are to write a program that reads the file and displays the following information for those schools that offer a BS degree in Computer Science. Consider only thosÉ schools that offer a BS in Computer Science on campus. Best and worst retention rates showing the school name and retention rate as a percentage Highest and lowest in-state cost showing the school name and cost Some of the cost and retention data is incomplete. Missing data is given as-9999. Do not consider any data with the value -9999.
