Java Variables

 Java Variables 

A variable is a holder which holds the worth while the Java program is executed. A variable is allocated with an information type. 

Variable is a name of memory area. There are three kinds of factors in java: nearby, example and static. 

There are two kinds of information types in Java: crude and non-crude.

Variable 

A variable is the name of a saved region allotted in memory. At the end of the day, it is a name of the memory area. It is a mix of "differ + capable" which implies its worth can be changed.

int data=50;//Here data is variable  

Types of Variables

There are three types of variables in Java:

• local variable
• instance variable
• static variable

1) Local Variable 

A variable announced inside the body of the strategy is called nearby factor. You can utilize this variable just inside that technique and different strategies in the class aren't even mindful that the variable exists. 

A nearby factor can't be characterized with "static" catchphrase.

2) Instance Variable

A variable announced inside the class however outside the body of the strategy, is called an occurrence variable. It isn't pronounced as static. 

It is called an occurrence variable since its worth is example explicit and isn't divided between occasions.

3) Static variable 

A variable that is declared as static is called a static variable. It cannot be local. You can create a single copy of the static variable and share it among all the instances of the class. Memory allocation for static variables happens only once when the class is loaded in the memory.
