before you start reading this.
visit this topic if you got no idea what is int,double,float,string etc etc http://www.maxcheaters.com/forum/index.php?topic=113286.0
Skip it if you already learned this small shits. :P
INTRO:
The java programming language was developed by Sun Microsystem as an object-oriented language that is used both for general-purpose bussines programs and interactive World Wide Web based Internet programs. It is architecturally neutral, which means that you can use the Java programming language to writte a program that will run on any platform. A program written in the Java programming language is compiled into Java Virtual Machine cose, called bytecode.
Another advantage of Java is that is simpler to use then many other object-oriented languages. The Java language is modeled after the C++ programming language and it eliminates some of the most difficult features to understand in C++.
Methods
A method must contain
• A declaration (or header or definition)
• An opening curly bracket
• A body
• A closing cruly bracket
The method declaration contains the following:
• Optional access modifiers (public)
• The return type for the method (void)
• The method name
• An opening parenthesis
• An optional list of method arguments
• A closing parenthesis
Creating methods with No Arguments.
A method is a series of statements that carry out some task. Any method that is classwide method requires the keyword modifier static. You place the method within the program that will use it but not within any other method. If you place a method call within a class that does not contain the method, you must use the class name, followed by a dot, followed by the method. Any class can contain an unlimited number of methods. Within a class, the simplest methods you can invoke don’t require any arguments or return any values. Let’s take an example.
public class First
{
public static void main(String[]args)
{
System.out.println("First java program")
}
}
Supose you want to add three additional lines of output to this program to display your company name and address.
public class First
{
public static void main(String[]args)
{
nameAndAddress(); < --- calling the method without arguments
System.out.println("First Java programm");
}
public static void nameAndAdress() < --- placing the method without arguments
{
System.out.println("Erol Corporation");
System.out.println("Albania,Tirana");
System.out.println("Mxc");
}
}
Let’s make another class to show how we can call a method from another class.
public class ipwn
{
public static void main(String[]args)
{
spammer()
System.out.println("ipwn")
}
public static void spammer
{
System.out.println("spammers");
System.out.println("deserve");
System.out.println("to die");
}
}
Ok now here we go:
public class test
{
public static void main(String[]args)
{
System.out.println("Calling method from another class");
ipwn.spammer();
}
}
………………………………………………………………………………………………………………..
Method that require a single argument
public static void predictRaise(double moneyAmount)
{
double newAmount;
newAmount=moneyAmount*10;
System.out.println("raise salary is"+newAmount);
}
public class adenaRaise
{
public static void main(String[]args)
{
double mySalary=200;
System.out.println("Demostrating some raises");
predictRaise(400);
predictRaise(mySalary);
}
public static void predictRaise(double moneyAmount)
{
double newAmount;
newAmount=moneyAmount*10;
System.out.println("With raise salary is"+newAmount);
}
}
Methods that require multiple arguments
You can pass multiple aeguments by listingthe arguments within the call to the method and separating them with commas,
public static void predictRaiseGivenIncrease(double moneyAmount,double percentage)
{
double newAmount;
newAmount=moneyAmount*(1+percanRate);
System.out.println("With raise salary is"+newAmount);
}
The arguments are separated by a comma, and each argument requires its own named type (in this case both are double)as well as an identifier.
Methods that return values
The return type for a method can be any type used in the Java which includes the primitive types int,char,double etc. as well as class types. For example
Public static void asdasd()
This method is public and it returns no value, so it is type void.A method that returns true or flase might be public
Boolean asdasd()
public static int calculateAge(int currDate)
{
int years;
years=currDate-1977;
return years;
}

Topic is going to update later (need add and some shits) coz i need sit down for 2 hours now and read smth about Macro Economy, in 3 hours i have a big exam to give.
Hope i helped anybody.
