Many languages such as Java and C use what is known as ''strong'' or ''static'' variable typing. This means that when you declare a variable in your application code you must define the variable type. For example if the variable is required to store an integer value, you must declare the variable as an integer type. With such languages, when a variable has been declared as a particular type, the type cannot be changed.
