Exception

No, When super class method throws exception then subclass does not throws the same Exception

Yes, we can

Code
package sample;
 
 class Super {
 
        
                void foo() throws NullPointerException 
                { System.out.println("Super");
                }
                }
                class SupSub extends Super {
                void foo()throws NullPointerException
                { 
                        System.out.println("SupSub");
                }
                }
        public  class super123{
                
                public static void main( String[] argv ) { 
                        SupSub sup=new SupSub(); 
                        Super spr=new SupSub();
                        spr.foo(); // Output SupSub }
                } 
 
}
 

Here foo can skip adding throws NullPointerException because is an unchecked exception
class SupSub extends Super {

void foo()throws NullPointerException

{

System.out.println("SupSub");

}

}

Yes we can ..sub class can throw same or subclass of that exception
