Answer:
Instantiate the object and access the variable using object reference.
Explanation:
In order to use/access an instance variable in a class, the class needs to be instantiated.For example:
class Demo{
//Instance variable declaration
int testvar=0;
public static void main(String args[]){
//Class instantiation
Demo d = new Demo();
// The instance variable is accessed using the object reference
d.testvar = 1;
}
}
In case the instance variable in private then it can be accessed using its corresponding getter/setter methods.
