This blog  deals with ARRAY – Seminar – 1.1.0.  Some of the illustrations are discussed below.      In the previous blog ARRAY – Seminar – 1.1.0 in Java – Payilagam – Part – I we have already explained about some finer examples . Again in the upcoming blogs we are dealing with the Array – 1.1.0 . They are mentioned below as follows :   REFERENCE : ( For ARRAY – Seminar – 1.1.0 in Java – Payilagam – Part – I  ) https://payilagam.com/wp-admin/post.php?post=15819&action=edit _______________________________________________________________________________                     Declaring a Variable to Refer to an Array The preceding program declares an array (named anArray) with the following line of code: // declares an array of integers int[] anArray; Like declarations for variables of other types, an array declaration has two components: the array’s type and the array’s name. An array’s type is written as type[], where type is the data type of the contained elements; the brackets are special symbols indicating that this variable holds an array. As with variables of other types, the declaration does not actually create an array; it simply tells the compiler that this variable will hold an array of the specified type. Similarly, you can declare arrays of other types byte[] anArrayOfBytes; short[] anArrayOfShorts; long[] anArrayOfLongs; float[] anArrayOfFloats; double[] anArrayOfDoubles; boolean[] anArrayOfBooleans; char[] anArrayOfChars; String[] anArrayOfStrings; You can also place the brackets after the array’s name: // this form is discouraged float anArrayOfFloats[]; However, convention discourages this form; the brackets identify the array type and should appear with the type designation.          Creating, Initializing, and Accessing an Array One way […]

The length of an array is established when the array is created. After creation, its length is fixed.  An array of 10 elements. Each item in an array is called an element, and each element is accessed by its numerical index. As shown in the preceding illustration, numbering begins with 0. The 9th element, for example, would therefore be accessed at index 8.                                                2.Array Creation Syntax: 1.Declaring Array  type[ ] arrayname = new type[size] ;  type can be primitive type or Object class or sub class of Object class or user defined class. 2. Initializing Array arrayname[0 th index] = value; // Late initialization  .  .  arrayname[n th index] = value; // Late initialization n th index=arraysize-1. n th index=arraylength-1 3.Creating Array with initialization  Syntax:  type[ ] arrayname ={value1,value2,….,value n};  type can be primitive type or Object class or sub class of Object class or user defined […]
