you can compute it by dividing by 100 (removes the last 2 digits) and then mod'ing by 10 (only keeps the last digit)
(x / 100) % 10

Reflection. you need it when you want to invoke a method by reflection. A method does not have to be public to be invoked. However, you will need to know how to get it. (Class.getMethod() will not...

Yes, they are called "reference types". The references point to objects.
.

You mean that you cannot have objects as values, then yes.


Yes, they are called primitive types.


Basically....

No. You compile it once to .class files. Then you run the .class files with "java MyClass".

you could either get all the digits out into a list or something, and then parse them back into a number in reverse

or just take the input as a string and reverse the string

why don't you post code that actually compiles?

why don't you post the exception and stack trace, and post the code inside code tags

also this code is wrong

Well are you using Generics? Maybe you should.
http://java.sun.com/j2se/1.5.0/docs/guide/language/generics.html

in java objects are always referred to using "references", which are kind of like pointers in C, except that you can't do silly stuff with them

can we see more code? for example, what types are all these things? how are they defined?

This line makes no sense; you are getting the value that is associated with the key "info", and then you are testing whether that value is a key in the hash table?

no

um... where is your code?

x.multiply(y)

why don't you show us what your problems are

http://en.wikipedia.org/wiki/Hash_table

so lets look at line 112:
truckinfo[i].Set(inputhp, inputmileage, inputyear);

The two references that you dereference in that line are "truckinfo" and "truckinfo[i]". "truckinfo" isn't null...

but that doesn't insert it in the right place

inner classes are nice because they can implicitly access the fields of the enclosing instance, so if your buttons were pointed to by a field, then you can use an inner class to access them

yes, use Iterator if possible

um.. so for starters, you know that you can only put code in methods? you can't have statements randomly outside methods

it appears to be an applet. you usually have to embed the applet in an HTML page using applet tags and use a browser to run it

you should have
int starB=10;
inside the outer while loop

do you mean, "it doesn't compile"? there are no classes named Widget, Spork, or Grommet; how do you expect to create new objects of those classes?

can you post your entire code?

yes. (except that in Java the first object is garbage-collected and in C++ it isn't)

you should read a basic guide to Java

Java consists only of primitive types and reference types (which are kind of like pointers in C). Reference types point to objects, and are named after the...

"b" and "c" are references (like the previous poster said, kind of like pointers in C) which may point to objects. objects are not values in java; instead, you always manipulate them through...

um... you have random code outside of a method, in the declaration of class "carinfo"

what exactly is your question?

why can't the classes be separate and you just put each class in its own file?

also the "main" method should be static

if you really want to know, the members of an array are specified in JLS 10.7 (http://java.sun.com/docs/books/jls/third_edition/html/arrays.html#10.7)

i think something's actually wrong with your logic. i can't see your code, so I don't know what methods like getIndex(), setChild(), and stuff do; but... your recursion only stops if i == m, where i...

it's really hard to tell what you are doing without seeing some code

in your "tree", do the nodes have references to their children; if so, then the children are not garbage collected, because...

your remove() method doesn't have a closing brace

perhaps this has to do with your two opening braces after the if

it's not security (there are ways to get access to private fields and methods anyway), it's called abstraction

the idea is that if people can access stuff, then they will write code which will...

isn't it printed out by your program?

your add(), subtract(), multiply(), and divide() methods modify their arguments, without changing them back; i am not sure if this is what you want

i don't understand your reduce() method. it...

one reason why you might want to & 0xFF is that byte's are signed, so if "data" is a byte array, and some of the bytes are 128 or above, then they will be interpreted as being negative. and when they...
