void Method Definition
SYNTAX
public void Method_Name ( Parameter_List )
{
<List of statements>
}
If there are no Parameters , then the parentheses are empty.
EXAMPLE
public void writeOutput( )
{
System.out.println(month + " " + day + ", " + year);
}
All method definitions are inside of some class definition. See Display 4.2 to see these
example method definitions in the context of a class.
When an instance variable name is used in a method definition, it refers to an instance
variable of the calling object.
return Statements
The definition of a method that returns a value must have one or more return statements.
A return statement specifies the value returned by the method and ends the method
invocation.
SYNTAX
return Expression ;
EXAMPLE
public int getYear( )
{
return year;
}
A void method definition need not have a return statement. However, a return statement
can be used in a void method to cause the method to immediately end. The form for a
return statement in a void method is
return ;
