### Array in java

- IN the Java programming language arrays are objects , are dynamically

created, and may be assigned to variables of type Object . All methods of

class Object may be invoked on an array. - An array object contains a number of variables. The number of variables may

be zero, in which case the array

is said to be empty. - The variables contained in an

array have no names; instead they are referenced by array access expressions that

use nonnegative integer index values. - These variables are called the components

of the array. If an array has n components, we say n is the length of the array; the

components of the array are referenced using integer indices from 0 to ,

inclusive. - All the components of an array have the same type, called the component type

of the array. If the component type of an array is T, then the type of the array itself

is written T[]. - The value of an array component of type float is always an element of the

float value set ; similarly, the value of an array component of type double

is always an element of the double value set. - It is not permitted for the value of an

array component of type float to be an element of the float-extended-exponent

value set that is not also an element of the float value set, nor for the value of an

array component of type double to be an element of the double-extended-exponent

value set that is not also an element of the double value set.
