(10 pts) Assume that you want to use both an input file callled "myinput.txt" and an output file called "myoutput.txt" which are located in a folder called "mydata" on the g: drive. In the program below, fill in all the missing details so that you can read a series of values (one by one) from the input file into the variable "num". Continue to read values and process them until you have processed the value 64 (not 64 items , but an item whose value is 64) At the end, print the total number of values read from the file to the output file. To do this you may have to declare additional variables, include statements to control reading from and writing to files, et.. l/needed to use Scanner Class l/needed for File IO import java.util.

Answer 1

        public static void main(String[] args) throws IOException{
                
                
                int num, count = 0;
                Scanner reader = new Scanner(new File("g://mydata/myinput.txt"));
                PrintWriter writer = new PrintWriter(new File("g://mydata/myoutput.txt"));
                                
                do {
                        num = reader.nextInt();
                        count++;
                } while(num != 64);
                
                writer.println("number of values read: " + count);
                
                reader.close();
                writer.close();
   }
