Methods -- Style 1
Style 1: Our first style of
method will simply perform an independent
task. It will not receive any parameters and it will
not
return
any values. Such a method definition starts with the reserved words
public static void, followed by the name of the method and
a set of parentheses. The word public
indicates that there are no restrictions on the use of the method. The
word static means that all of the method's data
will come from parameters or internal computations, with no reference to
variables. The
word void is used to indicate that no value is
returned.
//Demo Program for Methods
import java.io.*;
import BreezyGUI.*;
public class DisplayClass
{
public static void main (String[ ] args)
{
System.out.println("Calling all methods!");
asterisks( ); //invoking method
(calling the method)
System.out.println("Great
job, method!");
asterisks( ); //invoking method
again
System.out.println("We're outta here!");
}
//Method for astericks
public static
void asterisks( ) // Method definition
{
int count;
for(count = 1; count<=20; count++)
System.out.print("*");
System.out.println( );
}
}
Output:
Calling all methods!
********************
Great job, method!

We're outta here! |
