Java Syntax, Level 2, Lesson 8

when to use 'else if' statements I feel my code should be close I have tried a ton of different codes to get the minimum but in the end it always prints out C regardless of if it is the max or min. the 'else if ' statement never works and says there is an error because there is and 'else' without an 'if'. Can someone explain to me what that error means?

PLease help Keep getting the following mentor recommendation: When there is an odd number of bytes in the first file, your program writes the smaller half of the bytes. It should write the larger half. When there is an odd number of bytes in the first file, your program writes the larger half to the third file.
