Program Plan Intro

Java Method calling:

  • The java method is a collection of statements used to perform certain operations.
  • The method should be called in order to use it. The methods can be called in two ways,
    • Method returning a value
    • Methods returning nothing
  • The method calling process is very simple. When calling a method, the program control gets transferred to the called method.
  • The above stated called method returns control to the caller in two separate conditions. That are,
    • The return statement is executed.
    • It reaches the closing brace of the method.
  • The arguments of the method call should be same as in the definition of the method.

a) Write a boolean method called sumDivisibleByFive that returns true if the sum of the digits of its integer parameter is divisible by 5 and false otherwise. For example, if the parameter passed to the method is 73 then the sum of its digits is 10 (7+3) The method should return true since 10 is divisible by 5. b) Write a main method that calls the method sumDivisibleByFive for the values between 10 and 100 inclusive 10 per line. This should output the following numbers: 14 19 23 28 32 3741 46 50 55 64 69 73 78 82 87 91 96
