Explanation:
Slap is caused when engine is cold
Piston slap is moves ups and down in the engine block.Air and fuel explodes inside the chamber.Piston is connected to pin.
The Piston can be sufficiently enormous with the goal that the cylinder rocks starting with one side then onto the next to cause the cylinder slap. Aluminum squares will in general effectively capitulate to this issue than others.
Piston that experience increasingly chilly leeway acquire speed when the cylinder moves from the minor to significant push side and this causes the cylinder slap.
Answer:
None of the mentioned options
Explanation:
- If we define a method in a derived class with same declaration type as that of base class then it is said to be overriding a function which behaves differently which will depend on the object which is calling the method.
- Option a,b and c are not any kind of methods we implement using coding.
- Option d is done when number or data types of parameters are different than the declaration of the base type.
Answer:
A generalized class used only to create related derived classes
Explanation:
An abstract class is a class which cannot be instantiated on its own. It is defined using an abstract keyword. However, an abstract class can be inherited from and the derived class can actually be instantiated. For example:
abstract class A{
}
class B extends A{
void test(){
}
}
Here class A is an abstract class, while class B inherits from A. Now we can create an instance of class B as follows:
B b = new B();
b.test();
