Methods are used to for plenty of reasons:

  • Cleaner code
  • Code re-usability
  • Easier maintenance
  • Code readability

 

How does method actually look like?

Method consists of method signature and method body.

 

Method signature signature always look like this:

  • Access modifier
  • Return type or void
  • Method name
  • Parameters

 

 

And After method signature we have

  • Opening curly brackets
  • Method body/our logic
  • Closing curly brackets

 

 

Let’s dissect this method:

 

Our method could be void, meaning that method will not return any value.

 

Of course, our method can also be parameter-less, contain multiple parameters or with different access modifiers. We could also have multiple methods with same name but will have to have different parameters or at-least different order of same parameters.
