When I write string name, it shows that local variable value not used even if I give it a value.

Answer 1

I think you are confused with class variable and method variable, it will be good idea if you show us your code.

Answer 2

Not use is different from uninitialized, try to display it or something

Answer 3

I wrote
{
class siloniya
public static void main(String[ ] args){
String name ="Rahul";
}
}

Answer 4

And when I wrote this it said, "local variable is not used."

Answer 5

yes it is local variable inside the main method , its just a warning and not an error, it warns you that you declared a variable but never used it.

Answer 6

But when I run it, it doesn't output anything.
