Explain Parentheses in Java ?
Sometimes the default sequence of evaluation isn't what you want. For example, the formula to change a Fahrenheit temperature to a Celsius temperature is C = (5/9) (F - 32) whereas C is degrees Celsius and F is degrees Fahrenheit. You must subtract 32 from the Fahrenheit temperature before you multiply by 5/9, not after. You can use parentheses to adjust the frequently much as they are used in the above formula. The further program prints a table presentation the conversions from Fahrenheit and Celsius between zero and three hundred degrees Fahrenheit every twenty degrees. // Print a Fahrenheit to Celsius table
class FahrToCelsius {
public static void main (String args[]) { // lower limit of temperature table double lower = 0.0;
// upper limit of temperature table double upper = 300.0;
// step size double step = 20.0; double fahr = lower; while (fahr <= upper) { double celsius = (5.0 / 9.0) * (fahr-32.0); System.out.println(fahr + " " + celsius); fahr = fahr + step; }
