Because it isn't. The Exception class is a super class of both IOException and FileNotFoundException, so the parent can throw an IOException, a FileNotFoundException, and a ton of other checked exceptions that the child can't throw.

class Parent {
static Integer number;
}

class Child extends Parent {
Integer number;
}


this is compiling? but why? aren't we not allowed to have a new method same as static method but without the static word?
