Methods are composed by 5 elements:
METHOD SYNTAX:
[Access modifier][Visibility][Return type][Method name] {Parameters}
DETAILS:
* ACCESS MOD (Optional):
> private
> public
> protected
* VISIBILITY (Optional):
OPTIONS:
> static (Denies the method as belonging to a single object)
* RETURN TYPE (Mandatory, except for Constructors):
OPTIONS:
> primitive types (int, char...)
> arrays
> Objects (Custom types)
> void (For non-returning methods)
* METHOD NAME (Mandatory, for storage purposes):
Custom
* PARAMETERS (Optional):
DEFINITION: A list of variables to be passed into the method.

[Parameter type][Parameter name (Identifier)]
CODE EXAMPLES:
public static void main(String args[])
{
// *** CODE ***
// returns nothing
}
float sum(float n1, float n2)
{
return n1 + n2:
}
int[] getSequence(int start, int end)
{
// returns an array
return new int[] {start, end};
}
OBS:
The return keyword followed by a value of compatiple type is madatory for non-void returning methods.
Hope to be useful. May God bless you
