[JAVA] Glossary: Member Variables / Local Variables

What is a member variable?

• Variables in the class
• Definition of object attributes
• Variables for receiving data
• Parameters of the object

Example

Conceptual image

Object: Our rabbit ... thing Member variables: cute, scared, clumsy ... what is it like? Method: Sleep, eat, bounce, run ... how can you move?

Code image

public class Rabbit{

	Int age;		//Store member variable age
	String personality;	//Store member variable personality


	void setAge(int newAge){
		age = newAge;
	}

	Int getAge(){
		return age;
	}
}

What are local variables?

• Variables that can only be referenced in a limited range within the program

• Variables declared inside a method cannot be referenced outside the method

• Variables declared in if and for statements cannot be used outside the clause

• Phrase: The smallest unit that divides a sentence into an actual language to the extent that it is not unnatural.

• Variables declared as members of a class (member variables) cannot be referenced from outside the class.

Example

Public class Variable{
	Public static void main(String[] args){
		String rabbit; 
		//Local variables that can only be referenced within the main method
	} 
}

I will add it when I come up with it.
