Answer:

"test of B called"

Explanation:

  • The object is created for the D class, but there are two test methods in class B and C.
  • The D class does not hold any test method. So when the object called the test method. Then the B method is called.
  • It is because the B class is declared first in the inheritance of D class like in the statement "class D(B, C)".
  • If the statement will be "class D(C, B)", then the C method will be called.
  • if the D class holds the method test, then only the D method will be called.
  • Hence the output is "test of B called".

german

Answer:

The Java Program for the given problem is as below. Directly copy the code and run it on your machine.

Explanation:

Refer the Screenshots attached for the output.

import java.io.BufferedReader;

import java.io.InputStreamReader;

public class TheSpeedOfSound {

public static void main(String[] s)

{

String medium;

double distance;

double time;

try{

BufferedReader choice = new BufferedReader(new InputStreamReader(System.in));

System.out.println("Enter one of the following: air, water, or steel: ");

medium = choice.readLine(); // reading input i.e. air, water or steel

//check for air water and steel

if (medium.equalsIgnoreCase("air") || medium.equalsIgnoreCase("water") || medium.equalsIgnoreCase("steel")){

System.out.println("Enter the distance the sound wave will travel: ");

distance = Double.parseDouble(choice.readLine()); // read distance value if it is air water or steel

switch (medium)

{

//if medium is air

case "air":

time = distance/1100;

System.out.print("It will take " + time + " seconds.");

break;

//if medium is water

case "water":

time = distance/4900;

System.out.print("It will take " + time + " seconds.");

break;

//if medium is steel

case "steel":

time = distance/16400;

System.out.print("It will take " + time + " seconds.");

break;

}

}

else{

System.out.print("Sorry, you must enter air, water, or steel.");  

}

}

catch(Exception e){

e.printStackTrace();

}

}

}

Jump to Question: Fill in the blanks below: The flow of electricty is similar to the movement of water through a pipe. The movem
HACTEHA [7]

The answer is;

Current  

Voltage  

Power/Wattage  

Circuit

Water moving through pipes is like electricity flowing in a circuit. The flow of electricity is an actual flow of electrons. That movement of electrons is what is known as current. Think of current as the volume of water flowing through a water pipe. The electrons need some force or pressure to move, and so is water in a pipe. The voltage is that electromotive force; the pressure that pushes the electrons in a system. The power measured in Watts is the rate at which the energy is consumed. For the current to flow the circuit must be complete. Otherwise we cannot say that we have power if the circuit is not closed.

Identify any eight new programming languages and classify them based on their functionality.
shepuryov [24]

Answer:

Some of the new programming languages are R, Python, Haskell, Swift, C++, Java, Javascript and PHP.

However, you should know that in general sense there are three types of programming languages.

R is a pure object-oriented programming language being used for scientific purposes, and now it is being used extensively for machine learning as well.

Python is also a pure object-oriented programming language, and it is being used for mainly machine learning. However, you need to keep in mind that it supports the functional programming paradigm as well.

Haskell is a functional programming language and is the best in the functional paradigm as well. You can compare it with LISP, FORTRAN and PASCAL or COBOL, and you will find that Haskell is the best.

Swift is a pure object-oriented programming language, And by pure it means it never cheats anybody like if it says a variable is an int, it will be an int and not like C# here a string data type can be an integer data type. And this is not the correct thing. However, if you study in deep, you will find it is a necessary evil.

C++ and Java are imperative programming languages.

The Javascript and PHP are the scripting languages that support the object-oriented programming concepts but not fully, and they too fall under the imperative programming language list.

Explanation:

The answer is self explanatory.
