Chapter 7, Problem 1SA

Explanation of Solution

Array:

An array is defined as a group that consists of similar data types.

• The array size must be specified by an “int” value and not long or short.
• In Java, all arrays are allocated dynamically.
• An array is always indexed, starting from 0.

Example:

//Create an array variable with size 3

int i[] = new int[3];

In the above statement,

• The “int” refers the data type of the array.
• The “i” refers the name of the array.
• The keyword “new” refers the new memory allocation.
• The “int[3]” refers the size of the array.

Difference between array size declarator and subscript:

In the above example, “3” is the array size declarator and the index specified for each element in the array is called as subscript...
