Hi friend,
Local Variables: The variables defined in a method or block of code is called local variables. These variables can be accessed within a method or block of code only. These variables don't take default values if not initialized. These values are required to be initialized before using them.
------------------------------------
Here is the code.
public class NonStaticVariable{
int noOfInstances;
NonStaticVariable(){
noOfInstances++;
}
public static void main(String[] args){
NonStaticVariable st1 = new NonStaticVariable();
System.out.println("No. of instances for st1 : " + st1.noOfInstances);
NonStaticVariable st2 = new NonStaticVariable();
System.out.println("No. of instances for st1 : " + st1.noOfInstances);
System.out.println("No. of instances for st2 : " + st2.noOfInstances);
NonStaticVariable st3 = new NonStaticVariable();
System.out.println("No. of instances for st1 : " + st1.noOfInstances);
System.out.println("No. of instances for st2 : " + st2.noOfInstances);
System.out.println("No. of instances for st3 : " + st3.noOfInstances);
}
}
