Part 3 of 4 Write the header and definition of the method described below. NOTE: This method must be visible outside of the class and must not require an instance of the class to be invoked. binarySearch This method takes in an int array of sorted numbers and an int key to search for. It returns the index of the element in the array that matches the key. If no match is found, it returns -1. The method must implement a binary search algorithm. HINTS: Remember that the binary search algorithm determines which half of the set the data is in, divides that subset in half, and repeats.

Part 4 of 4 Write the header and definition of the method described below. NOTE: This method must be visible outside of the class and must not require an instance of the class to be invoked. writeResult This method takes in three parameters — a String representing the output file’s pathname, an int representing the key, and an int representing the index of the element in the array that matches the key — and returns nothing. The method must declare that a FileNotFoundException may be thrown during execution. This exception must be allowed to propagate outside of the method (i.e. it shouldn’t be “caught” within the method). This method must print the following message to the output file using a PrintWriter Target GTID found at index . or, if not found, Target GTID not found in the file. Sample output: Target GTID 555555555 found at index 4. This method must release (i.e. close) any resources before returning, even in the case where exceptions occur. HINTS: What mechanism can we use to guarantee that code is executed whether an exception occurs or not?
