Java has no global variables or functions

Every Java variable is part of some class, so you'll have to change your ways, and you'll feel a lot better about yourself. Looking for the abs() function? It must be in the Math class. Where is "stdin" defined? It's a public static field in the "System" class. Trying to find "atoi()"? Umm...ok, there it is: Integer.parseInt().

Java has no pointer and address operators

Java has no "struct" or "union"

A class is a bunch of variables and methods ("method" is just the object-oriented term for "function"). So why do we need a "struct"? It's just a class that happens to have no methods. And a union to save data of one type or another at a single location? That's what subclasses are for. If you don't know what a subclass is yet, don't worry: it's a basic OO concept, and you'll learn it as you learn Java.

Java has no pre-processor and no macros

• You define your "structs" there, but structs are gone now.
• You define TRUE and FALSE, but Java has the boolean type built-in.
• You define some simple function-like macros that are really hard to read and should probably just be functions, but you wanted to save a few milliseconds at runtime when your application ran on a 80286 processor. You're past that now.
• You have lots of "#ifdefs" to handle various compilers, various Operating Systems, and various hardware. Java takes care of all those inconsistencies for you. "Write Once, Run Anywhere", as they say.

Java does not have "unsigned" types

Java has no bitfields

Java has no operator overloading

x = person1 + person2;

 "person1.marry(person2)"

Java has no comma operator

Do we really need this operator in a language? Nah.

Java has no goto statement

Java has no function pointers

 Method method = Person.class.getMethod("getAddress", null);
// invoke the "getAddress()" method on object "joe"
Object address = method.invoke(joe, null);

Java has no enums

class MarriageStatus {
public static final MarriageStatus SINGLE = new MarriageStatus();
public static final MarriageStatus MARRIED = new MarriageStatus();
public static final MarriageStatus DIVORCED = new MarriageStatus();
}

Java has no "varargs"

Java does not allow multiple inheritence

Welcome to this great invention of Doctor Friend!

We all know that a name can tell a lot about a person. Names are not randomly chosen: they all have a meaning.
Doctor Friend knew this so he made another great invention just for the lonely you!

Sometimes you'd like to know if a relationship with someone could work out. Therefore Doctor Friend himself designed this great machine for you. With The Friendship Calculator you can calculate the probability of a successful relationship between two people. The Friendship Calculator is an affective way to get an impression of what the chances are on a relationship between two people.

This is just a fun application. Dont take it seriously.

Note: This is a funny logic in this testing if this example has caused any problems, please excuse me its only meant for fun!
