An array is a fixed-length data structure which can hold more than one value of the same data type.
All elements of an array are stored contiguously in memory.
Placing [] after the data type or after the variable name in a variable declaration.
int[] empId;
Or
int empId[];
The following are more examples of array declarations:
// salary can hold multiple float values float[] salary; // name can hold multiple references to String objects String[] name; // emp can hold multiple references to Employee objects Employee[] emp;
