of course...by using class name we can access static variables in instance method.. ex: class abc { static int a=20; public void g1() { System.out.println(abc.a); } }
Excellent Tutorial, Thanks a lot lot & Lots of Sir. I have a query. Suppose we declare a Local Variable and do some calculation and give and output which is again stored in a variable inside the method. Now i have to use this Variable value in some other methods say main Method or other method, How can i do this thing. Thanks.
Hi Pardeep kumar we will discuss the form and meaning of writing Java classes and Javadoc. .... In fact, I have put these methods in the Prompt class; also, one calls the other so ... a simply-namedmethod (with the parameters needed to do the calculation) ... Besides its single parameter, thismethod declares two local variables ...
you can call the method using some other method and then return the required variable's value to the caller method. So now you can store the returned value in some other variable and then use it. Hope this helps :)
sir when I am declaring variables with static keyword and calling it in the static method by using an object it is printing without any error. can you tell me the reason behind it?
I have one question. If the Static variable that we want to access reside on the same source file under same class, then it seems like we don't even need to use class-name.variable to call the variable. We can just directly call them be it static or instance area. But we need to use class name if we are using a different class inside or another source file. Then only you need to use class-name.static-variable.
Non Heap Means method area According to my understanding....... that means mainly we have three areas (1)method area (2)heap area (3)stack area................ In this Method area can access static variable,,static method,,non static method. In heap area non static variable and object creation is performed . in Stack area local Variable is accessed. thank u bro :-)
Hi Sir, i am able to acess static variable in below example without using class name in instance method ...please comment class Variable { static int a=40; static int b=50; public static void main(String[] args) { // TODO Auto-generated method stub Variable v=new Variable(); System.out.println(Variable.a); System.out.println(Variable.b); v.m1(); } void m1(){ System.out.println(a); System.out.println(b); } }
3 point in instance variable-- memory is allocated when object is created .. my question is-- if i do not want create object. how the memory allocated for the instance variable.
You cannot allocate memory to instance variable if you don't create an object. Reason is .. When you are accessing Instance variable inside static method you are creating an object and with that object you are accessing instance variable , So object creation is necessary. And when you are accessing Instance Variable inside Instance method you need to call that user defined instance method through main method so to call instance method through main method you again need to create an Object to access the instance method. So Object creation is necessary in every case according to my understanding. :)
Hello Ratan sir, it was a nice video with good examples.. When i try to execute the same examples , i observed that 1. without mentioning the class name also we can call the static variables in static main method.. public class Java_Static_Variables { static int a=10; static int b=5; public static void main(String[] args) { System.out.println(a); System.out.println(b); } Output:: 10 5 2. without mentioning the class name also we can call the static variables in instance user defined method.. public class Java_Static_Variables { static int a=10; static int b=5; public static void main(String[] args) { System.out.println(a); System.out.println(b); Java_Static_Variables x=new Java_Static_Variables(); x.m1(); } //Instance method public void m1() { System.out.println(a); System.out.println(b); } Output:: 10 5 10 5 please confirm and correct me if any mistakes.

Plz contact our online team durgasoftonlinetraining@gmail.com or call us on this number +918885252627,7207212427/28
Call with class name
We call static variable either class name or object reference but recommended to call class name always
Iam always follow s u
amazing explination
I have one question. If the Static variable that we want to access reside on the same source file under same class, then it seems like we don't even need to use class-name.variable to call the variable. We can just directly call them be it static or instance area. But we need to use class name if we are using a different class inside or another source file. Then only you need to use class-name.static-variable.
god bless u
what is non heap memory
Non Heap Means method area According to my understanding.......
that means mainly we have three areas (1)method area (2)heap area (3)stack area................
In this Method area can access static variable,,static method,,non static method.
In heap area non static variable and object creation is performed .
in Stack area local Variable is accessed.
thank u bro :-)
in static ..
can we not call the m1 method using class name ???like
test.m1();
sir .. class type lo Test t variable example ga cheparu kada adi eaa datatype ki vastundisir either int or charecter
phani phani user defined data type
sir, your teaching is very smart but still need to know, why we are using different type of variable. kindly advice me
I could not understand test t thing, how t. a or t. b gives the value of a and b respectively?
supeeeeeeeer,,.
please do upload oops concept videos ratan sir..
please open the sub branch of durgasoft in Bangalore sir.
Hi Sir,
i am able to acess static variable in below example without using class name in instance method ...please comment
class Variable {
static int a=40;
static int b=50;
public static void main(String[] args) {
// TODO Auto-generated method stub
Variable v=new Variable();
System.out.println(Variable.a);
System.out.println(Variable.b);
v.m1();
}
void m1(){
System.out.println(a);
System.out.println(b);
}
}
what meaning of non heap memory storage in static variable. so what is called.... non heap
3 point in instance variable--
memory is allocated when object is created ..
my question is-- if i do not want create object. how the memory allocated for the instance variable.
You cannot allocate memory to instance variable if you don't create an object.
Reason is ..
When you are accessing Instance variable inside static method you are creating an object and with that object you are accessing instance variable , So object creation is necessary.
And when you are accessing Instance Variable inside Instance method you need to call that user defined instance method through main method so to call instance method through main method you again need to create an Object to access the instance method.
So Object creation is necessary in every case according to my understanding. :)
Thank you
Ur god to me
static variables are stored in heap memory only but in permgen which is a section of heap memory. Its not non heap as you said.
Hello Ratan sir, it was a nice video with good examples..
When i try to execute the same examples , i observed that
1. without mentioning the class name also we can call the static variables in static main method..
public class Java_Static_Variables {
static int a=10;
static int b=5;
public static void main(String[] args) {
System.out.println(a);
System.out.println(b);
}
Output::
10
5
2. without mentioning the class name also we can call the static variables in instance user defined method..
public class Java_Static_Variables {
static int a=10;
static int b=5;
public static void main(String[] args) {
System.out.println(a);
System.out.println(b);
Java_Static_Variables x=new Java_Static_Variables();
x.m1();
}
//Instance method
public void m1()
{
System.out.println(a);
System.out.println(b);
}
Output::
10
5
10
5
please confirm and correct me if any mistakes.
