need to omit "2147483647*2147483647=1"

[Stan Austin]

so i have written code that takes three inputs (A, B and C)
if when multiplied any of the arguments equal the other it prints the corresponding sum;
i have used simple if statements

if (a*b==c) system.out.println(a"*"b"="c)
(a*c==b) system.out.println(a"*"c"="b)
(c*b==a) system.out.println(c"*"b"="a)

simple right? or not, after testing i found the args 1 21472147483647483647 2147483647
would output all three as correct. how do i prevent this from happening, i understand due to "overflow" this is infact correct (in binary terms) but i would like it to not print
1*2147483647=2147483647 2147483647*1=2147483647 2147483647*2147483647=1
but only
1*2147483647=2147483647 2147483647*1=2147483647
Thanks in advance guys

Sorry managed to post in wrong forum if a mod want to move to beginning in java, i would be grateful!
Thanks

what types are a and b?  (that's a hint as to what the problem is...)

[Stan Austin]

All three of them are ints the breif states use only ints

correction it state all three inputs must be ints... changing them in to longs though means it will not throw the exception so raises another issue right?

What exception won't be thrown?

What exception? There is no exception thrown if you suffer an arithmetic overflow.

The input must be Ints as such it would throw an exception if the argument entered was a long not an int.
however i realised that i could ask the user for the int, then long a2 = int a to convert the in to a long after the fact.
hence now resolved.
Thanks though guys!
