7 PM – Intro To Java – Gamas

Today We Do

1. we learned about Java methods, with and without return values.

Homework

1. Create a java file Nov18_MethodHomework.java
2. Inside this file, create a method
   • favoriteSport(String sport)
   • if the name parameter is “Volleyball” (non-casesensitive) print to the shell “Volleyball is a my favorite sport “.
   • otherwise print to the shell “<sport> is not my favorite sport”
3. Create another method, this time method with return value:
   • convertFromFahrenheighToCelcius(int fahrenheit)
   • it has one parameter: fahrenheit
   • the formula to convert from fahrenheit to celcius is

     • Celcius = (F - 32) * 5/9

   • So what you have to do is subtract 32 from the parameter fahrenheit and then multiple with 5 and divide by 9.
   • return the calculation.
   • The method needs to return a double data type.
4. Call each of the methods.
