How arrays are declared in Java? Explain with example?

Declaration of Array:

Array in Java may be declared in two forms :

1.       type   arrayname[ ];

2.      type   [ ] arrayname;

After declaring an array, we need to create it in the memory. Java allows us to create arrays using new operator only, as shown below :

Arrayname = new type[size];

Example :

number = new int[5];

average = new float[10];

These lines create necessary memory locations for the arrays number and average and designate them as int and float respectively. Now the variable number refers to an array of 5 integers and average refers to an array of 10 floating point values.
