Multilevel Inheritance
A Scenario where one class is inheriting/extending the bahavior of another class which in turn is inheriting behavior from yet another class.
Ex: public class Automobile {…}
Public class Car extends Automobile {…}
Public class Ferrari extends Car {…}
This multilevel inheritance actually has no limitations on the number of levels it can go. So as far as java goes, it is limitless. But for maintenance and ease of use sakes it is better to keep the inheritance levels to a single digit number.
A point to note here is that - using io packages is not mandatory. You need to use them only if you want to have some i/o operations in your code.

What is the use of import in java?
First, it's an error; it should be import java.util.*; That will make all classes in the java.util package availabe for use in your Java class definition. Java is divided up into packages. Each package can hold classes and other packages. java.util is a package.
How do the IO facilities in C plus plus differ from those in C?
The C standard library IO facilities are not extensible. For instance, the printf() and scanf() functions cannot handle user-defined types. However, the C++ standard library provides IO streams with insertion and extraction operators (<< and >>) that can be overloaded to support any user-defined type.
What is DMA in 8085 in microprocessor?
DMA stands for Direct Memory Access, in regards to 8085 MP. It consists of 2 pins, namely, HOLD and HLDA. The former of which indicates the processor that either a peripherial or any IO device, is requesting the processor to hold its current activites and give the control of buses to IO devices. HLDA, on the contrary, is the acknowledgement from the microprocessor to the concerned IO device sending the request.
What is the formula to convert voltage levels to decibels?
Here you find the formula to convert voltage levels to decibels. Scroll down to related links and look at "How to calculate dB?"
What is 'I am American' when translated from English to Italian?
Io sono Americano it is not necessary to use the personal pronoun for I which is io. Sono Americano is sufficient. The verb form sono implies I or io and using io is considered redundant or non native by Italians.
What is IO mapped?
Peripheral-Mapped IO is IO that is selected when the IO/M- line is high.
What does io mean in English?
If you are referring to the Italian word 'Io' which can be used in the sentence 'Io Sono', Io means I. Io sono means I am.
What is Peripheral-Mapped IO?
Peripheral-Mapped IO is IO that is selected when the IO/M- line is high.
Differentiate between memory mapped IO and IO mapped IO?
Memory mapped IO is one where the processor and the IO device share the same memory location(memory) while IO mapped IO is one where the processor and the IO device have different memory located to each other.
How do you cross blood types on a punnet?
If by heterozygous you mean someone has one allele for A (AA or Aa) type blood and one for O (ii), though a third allele, for type B, is also a possibility. If the parents are AA X Ai (phenotype would be A for both) then possibilities for the offspring are: Ai and AA, and all will be type A. If it's AA (A Blood) x AB (AB blood), then their children will be either AA or AB.
What moon is named io?
The moon Io.
Which of 'Io ho diciasettenne' or 'Io sono dicisettenne' is correct Italian?
When talking about age in Italian language you have 2 choices; 1. You use the verb "to have" or "avere" and say - "Io ho diciasette anni". That is the most common way of expressing age. 2. You use the verb "to be" or "essere" and say "Io sono diciasettenne". "Diciasettenne" means seventeen-year-old, so obviously we want to say "I am seventeen-year-old".

What is the birth name of Io Bottoms?
Io Bottoms's birth name is Io Cecilia Bottoms.
How do you xxplain how DMA offers an improvement over CPU programmed IO?
It offloads actual IO processing from CPU to the device hardware. This frequently allows the IO device to perform its operations on cycles that the CPU could not have made use of anyway, resulting in a double benefit.
What is the Difference between memory mapped IO and peripheral mapped IO?
A memory mapped IO device is an IO device that responds to a specific address when IO/M- is low. A peripheral (or IO) mapped IO device is an IO device that responds to a specific address when IO/M- is high.Many system designers ignore IO/M- in favor of memory mapped IO.This eliminates one term in the chip select logic for every device.This allows you to use all addressing modes and instructions when manipulating an IO device, as opposed to using only IN and OUT.This allows you to potentially have more than 256 different IO devices.The downside is that you reduce the addressable main memory in the system, i.e. you cannot have all 64K available to you, but this is not generally a problem in most controller designs. You also must decode 16 address lines instead of just 8 when accessing the device.
