The same as in other programming languages. A place to store a value. A variable may be of different types, including logical, string, numeric, or date. Here is an example that uses a variable: x = 5 ? "The square root of", x, " is ", sqrt(x). In FoxPro, it isn't necessary to declare variables. It is safer, though, in order to avoid conflicts between different modules, to declare the variable (usually with the LOCAL keyword if you use Visual FoxPro, or PRIVATE if you use the old FoxPro 1.x or 2.x). All variables are of a type which in some languages is called "variant", that is, the type can change at runtime.
There are two main categories of variables in Java. They are primitive and non primitive. Primitive data types are the basic data types like int, float, char etc. These are not objects. The other non primitive data types are all types of Java Objects. Example: String, ArrayList etc.
Primitive variables are variables that are not objects and carry primitive values like numbers, boolean etc. The primitive data types in java are:intbytefloatcharlongbooleanshortdouble
How a Java variable would act depends on the variable's data type. Variables of the primitive data types like int, char, float etc would not act as objects. But apart from them, all other data types would act as Objects. Almost all data types would extend from java.lang.Object and would behave as objects.

Yes it is.

Assuming the numbers are already in variables, just use the plus operator, for example: result = a + b
Turbo C variables are memory place holders for storage of data during the execution of a Turbo C program. Types of variables include integer, real and char.
how to learn foxpro
FoxPro 2 is text base procedurally-oriented programming language and DBMS. It does not support relationships between tables, it is not considered RDBMS. It has not transactional processing. But Visual FoxPro is an extension of FoxPro2 with supporting SQL query and data manipulation. While oracle is RDBMS.
