Question

Write in Java please

Answer 1

Answer: Provided in the section below

Explanation:

Using C# Code:

using System;

class Environment{

//temperature

private double temp;

//sets initial value of temp to 100 Fahrenheits

public Environment(){

temp=100;

}

//sets initial value to given temp

public Environment(double t) {

this.temp = t;

}

//returns temp

public double getTemp(){

return temp;

}

//calculates temp at given frequency

public void calcTemperature(double frequency){

temp=(frequency+40)/4.0;

}

}

class Cricket{

private Random r=new Random();

//frequency of birds

protected double frequency;

//sets frequency to a random value between 0-100

public Cricket(){

 

frequency=r.NextDouble()*100;

}

//sets frequency to a given frequency

public Cricket(double f) {

frequency = f;

}

//returns the frequency

public double getFrequency() {

return frequency;

}

//randomize the frequency

public virtual void randomFrequency() {

frequency = r.NextDouble()*100;

}

}

class ClemsonCricket: Cricket{

//sets the frequency to 80% of the parent's

public ClemsonCricket(): base(){

frequency=frequency*0.8;

}

//sets frequency to a given frequency

public ClemsonCricket(double f): base(f){}

//randomize frequency and sets it to 80% of the parent's

public override void randomFrequency(){

base.randomFrequency();

frequency=frequency*0.8;

}

}

public class testCrickets {

static void Main(){

Environment env=new Environment();

Console.WriteLine("Initial Temp: "+env.getTemp());

Cricket cricket=new Cricket();

env.calcTemperature(cricket.getFrequency());

Console.WriteLine(String.Format("Temp before changing Frequency: {0:0.00}",env.getTemp()));

cricket.randomFrequency();

env.calcTemperature(cricket.getFrequency());

Console.WriteLine(String.Format("\nTemp after changing Freqency: {0:0.00}",env.getTemp()));

Console.WriteLine("\nClemson Cricket: ");

ClemsonCricket clemsonCricket=new ClemsonCricket();

env.calcTemperature(clemsonCricket.getFrequency());

Console.WriteLine(String.Format("Temp before changing Frequency: {0:0.00}",env.getTemp()));

clemsonCricket.randomFrequency();

env.calcTemperature(clemsonCricket.getFrequency());

Console.WriteLine(String.Format("\nTemp after changing Freqency: {0:0.00}" ,env.getTemp()));

Console.WriteLine("\nPolymorphism Clemson Cricket: ");

Cricket Ccricket=new ClemsonCricket();

env.calcTemperature(Ccricket.getFrequency());

Console.WriteLine(String.Format("Temp before changing Frequency: {0:0.00}",env.getTemp()));

Ccricket.randomFrequency();

env.calcTemperature(Ccricket.getFrequency());

Console.WriteLine(String.Format("\nTemp after changing Freqency: {0:0.00}",env.getTemp()));

}

}

cheers i hope this helped !!
