जावा में तापमान गणना? - जावा, लूप, तापमान

मूल रूप से, कार्य तापमान की गणना करना हैएक फ्रीजर में डालने के बाद एक गर्म वस्तु। फ्रीजर का तापमान -20 डिग्री पर स्थिर है। एक बार जब ऑब्जेक्ट फ्रीज़र में होता है, तो इसका तापमान प्रत्येक सेकंड में (K * dt) डिग्री तक गिर जाता है, जहाँ K = 0.001 और dt, वर्तमान ऑब्जेक्ट तापमान और फ्रीज़र के तापमान के बीच का अंतर होता है। यह विधि कुछ सेकंड के लिए फ्रीज़र में रहने के बाद ऑब्जेक्ट के तापमान (शुरुआती तापमान के साथ) की गणना करने में सक्षम होना चाहिए।

समाधान में एक लूप की सुविधा होनी चाहिए जो गणना करता हैवस्तु के बदलते तापमान का दूसरा-दूसरा। प्रत्येक सेकंड में, तापमान (K * dt) से गिरना चाहिए जहाँ dt वर्तमान वस्तु तापमान (जैसा कि उस दूसरे के शुरू में है) और फ्रीज़र तापमान के बीच अंतर है यहाँ मेरा कोड है:

import java.util.Scanner;

public class Cooling {

public static final double FREEZER_TEMPERATURE = -20;
public static final double K = 0.001;

public static void main(String[] args) {
temperatureTest(70, 0);
temperatureTest(70, 60);
}

public static double temperature(double initialTemperature, int seconds) {
double x = initialTemperature;
int y = seconds;
double dt = (x - FREEZER_TEMPERATURE);
return K*dt*y ;
}

मेरी समस्या यह है कि मैं यह नहीं जानता कि इसे लूप में कैसे लागू किया जाए। किसी भी मदद की सराहना की जाएगी :) धन्यवाद। :)।

उत्तर:

यह विधि वह करेगी। मैंने प्रिंट स्टेटमेंट जोड़ा है ताकि आप प्रगति देख सकें, लेकिन आप इसे हटाना चाहते हैं।

public static double temperature(double initialTemperature, int seconds) {
double currentTemp = initialTemperature;
for (int time = 1; time <= seconds; time++) {
currentTemp -= K * (currentTemp - FREEZER_TEMPERATURE);
System.out.printf("After %d seconds, temperature is %f%n", time, currentTemp);
}
return currentTemp;
}

परीक्षा

System.out.println(temperature(70, 60));
