Compare the month / year of a string

Question

I am using an if statement to do a set of commands when an INT (which in this case is a number of a month like 02) is equal to a STRING (which is a date fully written out like so --> 02/14/1998) the fully written out dates are in a file

So I am asking the user to type in a date and a month (INTS) and compare that to the fully written out dates in the file and when the month is the month of the fully written out date and same w/ the year do a set of calculations.

    int userTypedMonth, userTypedYear
    string fileDate 
    if(userTypedMonth == fileDate && userTypedYear == fileDate){
          5+5=10
    }

I know this is the wrong syntax of code but i wanted to show how Im trying to explain it.

Is it a homework? You can try to take a look at java.util.LocalDate library: https://docs.oracle.com/javase/8/docs/api/java/time/LocalDate.html — Afshin Moazami, Oct 05 '17 at 00:07
You can turn the int to a String, but you definitely should not use `==` for strings — OneCricketeer, Oct 05 '17 at 00:08
Yeah, you must parse the date string. Then you can get the month and year integers to compare — OneCricketeer, Oct 05 '17 at 00:10
@cricket_007 anyway you could show me how to do that? I would really appreciate it — Matthew, Oct 05 '17 at 00:12

Once you have some date like object, then use something like getMonth and getYear — OneCricketeer, Oct 05 '17 at 00:17
@cricket_007 im trying and im still messing something up. Im pretty sure my parse syntax is wrong. — Matthew, Oct 05 '17 at 00:22

You can fileDate.split("/") to split the fileDate into a String[] where index 0 is the month ("02"), index 1 is the day ("14"), and index 2 is the ("1998"). Then you could compare using userTypedMonth.equals(fileDateArray[0]) and userTypedYear.equals(fileDateArray[2]), assuming the userTypedMonth/Year were Strings instead of ints. If they are ints, use String.valueOf(userTypedMonth/Year) to compare.
