You need to look into scriptEngine and Evaluator classes.
A variable typically consists of a name, a data type, a value, and a memory location where the value is stored. The name is used to reference the variable in the code, the data type defines the type of data the variable can hold, the value is the actual data stored in the variable, and the memory location is where the value is stored in the computer's memory.
A variable is a named memory address in which a value may be stored and mutated.
session is a server variable. it works like the ordinary variable but it is stored on the server
When you declare a variable and it's data type in a function, it is stored in the specific space for memory allocated by the variable type identifier known as the "stack."
A String is treated as an object, meaning there is an object on the heap. Of course, the variable you define is a pointer to the object, and it is stored on the stack.A String is treated as an object, meaning there is an object on the heap.

A variable is made up of a name (identifier) that represents a value stored in a computer's memory. It consists of a memory location where data can be stored and manipulated in a program. The value assigned to a variable can change during program execution.
Variable stored in the memory block inside the RAM. whenever we declare a variable it would take space in main memory and consume it's size from RAM.
Random Access Memory (RAM)
It depends entirely on what platform you are using. In an embedded environment, for instance global/static variables go into different RAM memory segments depending on whether or not they are initialised. constants are often left in ROM automatic variables are normally placed of the stack of the currently running task but not always.
A variable is an entity that may change its value. In a program, the result of the processing statements are stored in the computer's memory.
Either you get a compiler error. Or you get a compiler warning, and the variable won't be stored in register.
In a programming language, a variable is a name for a place where information is stored.
