Question

Preezing and Bolling Points The following cable lisrs the freezing and boiling points of several substanices. Substance Ethyl Alcohol Oxygen -173 -362 32 Boiling Point 172 -306 212 ter Design a class that stores a temperature in a temperature field and has the appropriate accessor and mutator methods for the field. In addition to appropriate constructors, the class should have the following methods: issthylFreezing. This method should return the boolean value true if the temipera- ture stored in the temperature field is at or below the freezing point of ethyl alcohol. Otherwise, the method should return false. 4sEthylBoiling. This method should return the boolean value true if the tempera- ture stored in the temperature field is at or above the boiling point of ethyl alcohol. Otherwise, the method should return false. , soxygenFreezing. This method should return the boolean value true if the tem perature stored in the temperature field is at or below the freezing point of oxygen Otherwise, the method should return false. isoxygenBoiling. This merhod should return the boolean value true if the e ture stored in the cemperature field is at or above the boiling point of oxygen. Other wise, the method should return false. * İskaterFreezing. This method should return the boolean value true if the tempera- tuce stored in the tempecature field is at or below the freezing point of water Other- . isผatorBoiling. This method should return the boolean value true if the tempera. ture stored in the temper ture field is at or above the boiling point of water Ocher wise, the method should return Ealse. wise, the method should return false. Wrice a program that demonscrares rhe class. The program should ask the user to enter a rempecatere, and then display a list of the substances chat will frecze at that remperature and those chát will boil at chat temperature. For example, if the temperature is -20 the class

Java basic programming course simple as possible use java import and comments to explain the code thanks in advance

Answer 1

package abc;

public class TemperatureClass {

private float temperature;

public float getTemperature() {

return temperature;

}

public void setTemperature(float temperature) {

this.temperature = temperature;

}

public boolean isEthylFreezing(){

if(this.temperature<=-173){

return true;

}

else{

return false;

}

}

public boolean isEthylBoliing(){

if(this.temperature>=172){

return true;

}

return false;

}

}

public boolean isOxygenFreezing(){

package abc;

import java.util.Scanner;

public class TempTester {

public static void main(String[] args) {

TemperatureClass temp=new TemperatureClass();

Scanner sc=new Scanner(System.in);

System.out.println("Enter temperature :");

float tempture=sc.nextFloat();

temp.setTemperature(tempture);

System.out.println(checkTemp(temp));

temp.setTemperature(65);

System.out.println(checkTemp(temp));

temp.setTemperature(-264);

System.out.println(checkTemp(temp));

temp.setTemperature(-43);

}

public static String checkTemp(TemperatureClass temp){

String freeze="";

String boil="";

if(temp.isEthylFreezing()){

freeze=freeze+"Ethyl Alcohol ";

}

if(temp.isOxygenFreezing()){

freeze=freeze+"Oxygen ";

}
