      Figure 8.1 shows an array of ten contiguous chunks of memory pointed to by a reference variable. This arrangement makes it convenient to refer to the element in each chunk of memory. Later we will see exactly how this is achieved. Arrays are regarded as real objects in Java. Array can be of primitive types or reference types.

      The first statement creates an array of bytes which is then used to create a DatagramPacket. The DatagramPacket will be used to receive a datagram from the socket because of the constructor used to create it. This constructor requires only two arguments: a byte array that contains client-specific data and the length of the byte array.

      We are interested in just the character at index 0. If a byte in the file does not correspond to a character, the method will throw an IllegalArgumentException. If the exception is thrown, display only the byte value and continue on to the next byte. Solution: See the code in ByteReader.java. Projects: 1.

      There are two composite types in Java, namely: array and string. Arrays are used to house more than one data values of the same type. Individual elements are accessed by use of the index. A string stores a fixed number of characters that cannot be changed. You can create an array of string objects.

      Note: 1) The index of the array in Java always starts at 0, therefore the number of elements specified will always be one greater that the upper index value. 2) Arrays are objects in Java and therefore must be instantiated using the key word new. The general syntax for creating an array is: type identifier[] = new type [number of elements];

      The java.io package contains classes that perform input and output. In Java, I/O classes are differentiated according to the type of data being read or written. Types of data that are dealt in Java are mainly: Byte-oriented Data. Numeric Data. Character Data. Byte oriented and numeric data is written with output streams and read with input streams.
