Java (Find the future date with if else statements)

Question

I have a question that I can\'t figure it out , Thank you: Write a program that prompts the user to enter an integer for today\'s day of the week (Sunday is 0 ,Monday is 1 ,

Answer 1

You can do it better by using an array to store the the day names.

String[] dayNames = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"};

Now you can use the user input as the index

int nameIndex = //... get input
//validate input
//dayNames[nameIndex] is the day of the week

Now get the input for number of days to add

int numDays = //...get input

Then just add that many days to compute the index for future day of week

int futureNameIndex = nameIndex; //start with entered day of week index
for(int i=0; i

I think you will find that one easier to understand. Finally

//dayNames[futureNameIndex] is the future day of week.
