Temperature conversion java gui how to#

Since the convert() method is static, no Object creation is required to call it. As we know execution starts from the main method in Java, so in the first line of the main method the compiler calls the static method ‘convert()’ and our defined method takes it from there. Finally, display it in the console using .Īfter completing the method definition for convert, we simply call it from the main method. Then we use the formulae to convert it to Fahrenheit. Subsequently, we ask the user to input the temperature value in Celsius and store it in a double type variable called ‘cel’. To avoid this simply type “sc.close()” at the end of the method. This says that the Scanner object is not closed. Notice carefully in the Output: A warning is being displayed beside the Scanner object declaration statement!.
