Here we have an array of length 5. In this section you will learn how to declare array in java.

Array declaration in java. Array variable has a type and a valid java identifier ie. The number is known as an array index. Pure dynamic arrays do not exist in java. For example int age new int5. In java each element in an array are associated with a number. The variables in the array are ordered and each have an index beginning from 0.
The arrays type and the arrays name. We can access elements of an array by using those indices. Java provides a data structure the array which stores a fixed size sequential collection of elements of the same typean array is used to store a collection of data but it is often more useful to think of an array as a collection of variables of the same type. Instead list is most encouraged to declare a static array of integer string float etc. Normally an array is a collection of similar type of elements which has contiguous memory location. Java array can be also be used as a static field a local variable or a method parameter.
Additionally the elements of an array are stored in a contiguous memory location. No size limit is considered for this. Use the bellow declaration and initialization statements. A java array variable can also be declared like other variables with after the data type. In this section you will learn how to declare array in java. In the image we can see that each element consists of a number array index.
Java array is an object which contains elements of a similar data type. The size of an array must be specified by an int value and not long or short. Java array declaration as we declare a variable in java an array variable is declared the same way. Fixed size array its size should be declared at start and can not be changed later dynamic array.
