An array is a collection of similar data types. Array is a container object that hold values of homogeneous type. It is also known as static data structure because size of an array must be specified at the time of its declaration. Array starts from zero index and goes to n-1 where n is length of the array.Standard Java arrays are of a fixed length. After arrays are created, they cannot grow or shrink, which means that you must know in advance how many elements an array will hold. Array lists are created with an initial size. When this size is exceeded, the collection is automatically enlarged. When objects are removed, the array may be shrunk.Oracle Selects Pearson VUE to Deliver Java, Oracle Solaris, MySQL and Other Former Sun Certification. Architect Certification (OCMJEA) 75 .
