can a interface variable be re assigned in abstract class

[sudheer kiran]

by default interface variables are public static final then what if the implementing class defines the same variable.

example here

 
interface IFACE{
int i =10;
}

abstract class ABS implements IFACE{
int i = 20;  // why doesnt not it give error,as it is over riding the interface variable.
}

the two "i" in the interface and class are different so there wont be any problem.

The variables in the interfaces are implicitly "public static and final" .

[Anant Jagania]

int i = 20; // why doesnt not it give error,as it is over riding the interface variable.

You cannot override interface/class variable in subclass or implementing class.

Only methods can be overridden.

Hence, variable "i" is different in interface and class.

In your example variable "i" for Interface is static final variable which is accessible globally while variable "i" in Abstract class is accessible only by the class.

how they both i's are different. interface final variables are inherited to implementing class.
in the implementing class how you can assign a new value.

[sudheer kiran]

 
class A {
	 final int i  =10;
}

class B extends A{
	 final int i = 20;	
}
public class Strs {
	public static void main(String[] args) {
		B b = new B();
		System.out.println(""+b.i);
	}
}

 

it seems the problem is not related to statics, i think variables(including final variables) can be redefined in subclass.
