I am a beginner in Java. I have been learning java by myself during the last few weeks and facing some difficulties with a question i got from a collegue of mine who did java at uni level. I don't know have to work with methods and she can't remember as well. Could some please help me out ??
A telephone cost plan:
Local calls are charged at $0.50 per minute(between 9a.m and 9pm). Long distance calls (> 200 miles) are charged at $1.10 per minute((between 9a.m and 9pm). From 9p.m to 9a.m,calls are charged at half the normal rate.
I have to write a program which calculates the total cost of an arbitrary number of calls. For each call, the person using the phone needs to enter a time value (in 24hr mode), a distance (in miles), and a call length (in minutes). The program must then display the cost of that call and also adds the cost onto a cumulative total.
When the phone user has no more calls to process, a time value of -999 instead of a legal time. When the program reads this sentinel value it displays the total cost of all the processed calls and ends.
Your help would be very appreciated.
