Question

Write a Temperature class in java and only assing the values if they are valid.

Temperature

Degrees:double                    between -50 and 150 F

Scale :char                            can be C or F

+Temperature ()                   default to 10 celcius

+Temperature(temp:double, scale:char) assign if valid

+get_Temp():double              returns current temperature value

+get_Scale(): char                   returns current scale

+set(temp:double,scale:char)void        set degrees and scale if valid

+set_Temp(temp:double)void               assings it if valid

+set_Scale(scale:char)voild                    coverts existing tmep to scale if valid

+covert_FtoC(temp: double)double     coverts F to returned C

Answer 1

package com;

public class Temperature {

double Degrees;

char Scale;

public Temperature() {

Degrees=10.0;

Scale='C';

}

public Temperature(double degrees, char scale) {

if(degrees>=-50 && degrees<=150 && (scale=='C' || scale=='F'))

{

Degrees = degrees;

Scale = scale;

}

}

public double get_Temp() {

return Degrees;

}

public void set_Temp(double degrees) {

if(degrees>=-50 && degrees<=150)

Degrees = degrees;

}

public char get_Scale() {

return Scale;

}

public void set_Scale(char scale) {

if(scale=='C' || scale=='F')

Scale = scale;

}

public void set(double degrees, char scale)

{

if(degrees>=-50 && degrees<=150 && (scale=='C' || scale=='F'))

{

Degrees = degrees;

Scale = scale;

}

}

public double convert_FtoC(double temp)

{

temp = ((temp - 32)*5)/9;

return temp;

}

}
