Answer 1

1. You missed space in parameter. Aa should be A a
2. While creating object, use this pattern:
class_name object_name = new class_name();
So, it should be A a = new A();

Answer 2

do you mean isn't working on the code playground or you don't know the answer

Answer 3

In the "main" method:
"A.a" --> "A a"

In the "foo" method's parameters:
"Aa" --> "A a"

"-->" = Change to

You just simply made a few simple mistakes when initializing an Instance of a class.

Output should be 1

Answer 4

Yeah, you might want to remove the first line in method foo. Otherwise the method does nothing.

Thanks.. I'm new so idk so much about java🙁🙁😥😥

Answer 6

@1of3 It wouldn't make a difference in the end either way, because a is not a public variable, nor does it return a value.

Answer 7

Original Code

class A{
int attr;
}
class Teat{
static void foo(A a){
a=new A();
a.attr=2;
}
public static void main(String [] args ){
A a=new A();
a.attr=1;
foo(a);
System.out.println(a.attr);
}
}
