ARRAY: (Core JAVA)

{              ArrayType [] arrayname; or

ArrayType arrayname[];

Arrayname= new ArayType[size];            } or

ArrayType[] arrayname= new ArrayType[size];

·         Array is a collection of similar type which has fixed size and it cannot store dissimilar type

·         Array can be initialize in 2 ways

(1)    By using dimensions

(2)    By using initialize

·         Syntax for initializing array using dimensions

ArrayType[] arrayname= new ArrayType[size];

·         Syntax for initializing array using initialize

ArrayType[] arrayname= { , , , };

·         Using array initialize, the elements are separated by ‘,’

·         We can refer each element of an array using index

·         The element of an array can be sorted by using sort method

·         Sort method is a public static method of array’s class

·         Array’s class belongs to a package java.util

·         sort method is overloaded method of arrays class. This method sorts the element of an array and stores the sorted element in the same array.

·         Array can be of 2 types

(1)    Primitive array- Boolean, int etc(PRIMITIVE DATATYPES)

(2)    Derived array- objects etc

·         If array of class type is created, then in that array we can store any type of object which is subclass to array’s class
