13 maj 2023 · Here are some key differences between global and local variables: Scope: Global variables have a wider scope as they are accessible throughout the class. Local variables, on the other hand, have a narrower scope as they are only accessible within the method or block in which they are declared.
The difference is where the variable can be accessed or modified. (in the contents of a class for example) A global variable can be accessed or modified anywhere within the class. A local variable, if created in a function within the class, can only be used within that function.
The scope of variables in Java will be explored in this section, along with their effects on how programmes are executed. There are four scopes for variables in Java: local, instance, class, and method parameters. Examining each of these scopes in more detail will be helpful.
