Introduction to Java Programming, Sixth Edtion. Java loops. Imagine you have to write a program which performs a repetitive task such as printing 1 to 100.
Coding 100 lines to do this would be mundane. There has to be an easier way, right? This is where loops come into the picture. Loops are specifically designed to perform repetitive tasks with one set of code. Loops save a lot of time.

Defining Methods (The Java™ Tutorials > Learning the Java Language > Classes and Objects) Here is an example of a typical method declaration: public double calculateAnswer(double wingSpan, int numberOfEngines, double length, double grossTons) { //do the calculation here } The only required elements of a method declaration are the method's return type, name, a pair of parentheses, (), and a body between braces, {}.
More generally, method declarations have six components, in order: Modifiers—such as public, private, and others you will learn about later.The return type—the data type of the value returned by the method, or void if the method does not return a value.The method name—the rules for field names apply to method names as well, but the convention is a little different.The parameter list in parenthesis—a comma-delimited list of input parameters, preceded by their data types, enclosed by parentheses, (). Modifiers, return types, and parameters will be discussed later in this lesson. Language « Java Tutorial. Internet FAQ Archives - Online Education - faqs.org.
