السلام عليكم

أولا هناك بعض الأخطاء في توابع التحويل التي ذكرتها .. و هذا تصحيحها :

public static double celsiusToFahrenheit(double celsius) {		
	// To convert Celsius to Fahrenheit, multiply by 1.8 and add 32 degrees. 
	double fahrenheit = celsius * 1.8 + 32;
	return fahrenheit;
}

public static double fahrenheitTocelsius(double fahrenheit) {
	// To convert Fahrenheit to Celsius, subtract 32 degrees and divide by 1.8. 		
	double celsius = (fahrenheit - 32) / 1.8;
	return celsius;
}

public static double feetToMeter(double feet) {
	// 1 foot = 0.3048 meters		
	double meter = feet * 0.3048;
	return meter;
}

public static double meterToFeet(double meter) {
	// 1 meter = 3.2808399 feet
	double feet = meter * 3.2808;
	return feet;
}

public static double kgToPound(double Kilogram) {
	// 1 kilogram = 2.20462262 pounds
	double pound = Kilogram * 2.2046;
	return pound;
}

public static double poundTokg(double pound) {
	// 1 pound = 0.45359237 kilograms	
	double Kilogram = pound * 0.4536;
	return Kilogram;
}

ثانياً :

تابع التحويل المجالي range convert :

public static void convertRange(int startingValue, int endingValue, int incrementStep, String conversionMethodName){
	if(conversionMethodName.equalsIgnoreCase("celsiusToFahrenheit")){
		System.out.println("Celsius"+"\t"+"Fahrenheit");
		for (int step = startingValue; step <= endingValue; step += incrementStep) {
			System.out.println(step+"\t"+celsiusToFahrenheit(step));
		}
	} else if(conversionMethodName.equalsIgnoreCase("fahrenheitTocelsius")){
		System.out.println("Fahrenheit"+"\t"+"Celsius");
		for (int step = startingValue; step <= endingValue; step += incrementStep) {	
			System.out.println(step+"\t"+fahrenheitTocelsius(step));
		}
	} else if( ...){
		// .....
	}
}

اشكرك اخي ابو خالد ,, و الله انك رجل شهم و ما قصرت و الله يبيض وجهك ,,

و لكن ماذا عن

(public static long convertTimetoMillis(int hours, int minutes, int seconds)

و getUserChoice method

وجزك الله خير

أهلاً بك أخت أريج ..

// A method that converts hours, minutes and seconds to milliseconds 
public static long convertTimetoMillis(int hours, int minutes, int seconds) {
	long millis = (seconds + minutes * 60 + hours * 3600) * 1000;
	return millis;

public static int getUserChoise() {
	String msg = "";
	msg += "\n1.	Convert from Celsius to Fahrenheit. ";
	msg += "\n2.	Convert from Fahrenheit to Celsius. ";
	msg += "\n3.	Convert from Feet to Meters. ";

	return n;
}

	while (true) {

		case 10:
