Variable

Variables are names associated with memory locations that store values. In most programming languages, the values stored in memory have a formal type. Depending on the static or dynamically typed nature of the language, variables may or may not allow the modification of the type at runtime.

Variables in various programming languages:

• Java variables
• Python variables
• Go variables
• Bash variables and parameters

Parameter

Function parameters in various languages:

• Java method parameters
• Python function parameters
• Bash variables and parameters

Argument

Function arguments in various languages:

• Python function arguments

Discussion

This terminology applies to Java method invocations, Python method invocations and even Java generics, where the ordinary parameters and variables are replaced with type parameters (type variables), and the arguments are replaced with type arguments.
