Problem with static methods

[Ganesh Kumar]

Hi friends,
Non static method cant be called from the static method that is true.But i have a done program below is it correct? If i do that what will be the problem

class palindrome{
static int a,b,c;
static void j(){
System.out.println("hi");
palindrome o=new palindrome();
o.g();
}
void g(){
a=10;
b=20;
c=40;
System.out.println(a+" "+ " "+b+" "+ " "+c );

}
public static void main(String args[]){
j();
}
}


Please clarify my doubt friends

Well, you can just try to compile it and see if you get any errors...

hey ,program is all correct and will run.you have created instance of palindrome class in static method and then calling nonstatic method on that instance which is ok.actually the constraint on nonstatic method is because static method is only one for whole class and does not have any information about any particular (instance of class)object so if you call nonstatic method directly (for ex simply j()) static method does not on which object method is to be invoked.but in this program you have created the instance of palindrome class so static method now have reference of object on which the method is to be invoked.
