How arrays are created in java?

Answer 1

Arrays are created just like other variables in Java.

Ex:

int[] a; // declares an array of integers

a = new int[10]; // allocates memory for 10 integers

a[0] = 100; // initialize first element

a[1] = 200; // initialize second element

Arrays are homogenous data types and hence they can contain values of only one type. If you create an integer array it can hold only integer data type values. If you try to assign values to nonexistent locations like a[15] it will throw an index out of bounds exception.
