• A field is a group of characters that has some meaning.
• A(n) record is a collection of fields that contain data about an entity.
• Random files are also called direct access files.
• InputStream and OutputStream are subclasses of the object class.
• The benefit of using a(n) random access file is the ability to retrieve a specific record from a file directly, without reading through other records to locate the desired one.
• After you create a FileSystem object, you can define a Path using the getPath() method with it.
• The BufferedWriter class contains a newLine() method that uses the current platform’s line separator.
• A file channel is seekable, meaning you can search for a specific file location and operations can start at any specified position.
• Because the backslash character starts the escape sequence in Java, you must use two backslashes in a string that describes a Path in the DOS operating system.
• A(n) file channel object is an avenue for reading and writing a file.
• A data file can be used as a(n) sequential access file when each record is accessed one after another in the order in which it was stored.
• A(n) key field is the field in a record that makes the record unique from all others.
• A(n) ByteBuffer is a holding place for bytes that are waiting to be read or written.
• An array of bytes can be wrapped, or encompassed, into a ByteBuffer using the ByteBuffer wrap() method.
• Any of the file input or output methods in a Java program might throw an exception, so all the relevant code in the class is placed in a try block.
• FileSystems is a class that contains factory methods, which assist in object creation.
• Java lets you assign a file to a(n) stream object so that screen output and file output work in exactly the same manner.
• Placing a file in the root directory of your storage device is equivalent to tossing a loose document into a drawer.
• Some text files are data files that contain facts and figures, such as a payroll file that contains employee numbers, names, and salaries.
• The getFileName() method returns the last Path element in a list of pathnames.
• When you use the BufferedReader class, you must import the java.io package into your program.
• Which of the following statements will write a line separator? BufferedWriter.newline();
• You can create a writeable file by using the Files class newOutputStream() method.
• You can use Java's Path class to create objects that contain information about files or directories, such as their locations, sizes, creation dates, and whether they even exist.
• Real-time applications require that a record be accessed immediately while a client is waiting.
• Reader is an abstract class for reading character streams.
• The String class split() method accepts an argument that identifies the field delimiter and returns an array of Strings.
• When you create an array of objects, each reference is assigned the value null.
• A(n) enhanced for loop allows you to cycle through an array without specifying the starting and ending points for the loop control variable.
• When any primitive type is passed to a method, the value is passed.
• When you declare or access an array, you can use any expression to represent the size, as long as the expression is a(n) integer.
• After you create an array variable, you still need to reserved memory space.
• A(n) flag is a variable that holds a value as an indicator of whether some condition has been met.
• When any primitive type (boolean, char, byte, short, int, long, float, or double) is passed to a method, the value is passed.
• When you declare or access an array, you can use any expression to represent the size, as long as the expression is an integer.
• When you declare int[]someNums = new int[10];, each element of someNums has a value of 0.
• When you perform a range match, you compare a value to the endpoints of numerical ranges to find the category in which a value belongs.
• It is a good programming practice to ensure that a subscript to an array not fall below zero, causing an runtime error.
• Individual array elements are passed by value when a copy of the value is made and used within the receiving method
• When a method returns an array reference, you include [] with the return type in the method header
