Java variables:
- The java variables are the containers to hold a value during the
program execution. - The variables can be declared in different data type according to the need.
- The variables are names to some memory location and these memory locations can hold values.
- The variables can have the data type, integer, character, float, double and so on.
- If a variable is declared as “int” data type, then this variable will hold an integer value. Likewise, “float” data type variable will hold a floating point value and so on.
- The value of a variable may change when the program start the execution if the change is mentioned in the program code..

(Business: check ISBN-10) An ISBN-10 (International Standard Book Number) consists of 10 digits: d1d2d3d4d5d6d7d8d9d10. The last digit, d10, is a checksum, which is calculated from the other nine digits using the following formula: (d1 * 1 + d2 * 2 + d3 * 3 + d4 * 4 + d5 * 5 + d6 * 6 + d7 * 7 + d8 * 8 + d9 * 9) % 11 If the checksum is 10, the last digit is denoted as X according to the ISBN-10 convention.
