Why don't you tell us. When you run the program, does the method return -1?

BTW, there are easier ways to detect if a file exists -- have you looked into some of the methods of the java.io.File class?

The best way to learn is to try things by yourself ,
for me it will not return -1 , and will give you this exception because there is no return type for the method "readFile()" it suppose to return int , to solve this , move the return statement after the finally clause ..


Thanks,

Or in the try body. It will then return something if the try body throws an exception and when it doesn't. Now it only returns something if it does.
