Just out of interest, is there a particular reason you want to learn Java? It’s very slow, and not at all preferred given that it’s not even available on the iOS system. How about Javascript, say even AJAX, Jquery? Otherwise you can try Udemy has some good tutorials

You should start learning the basics of programming in a language agnostic way.
This link has a collection of free resources, it also has a language agnostic section. It doesn’t need to be a language agnostic resource but if you are starting you need first to learn to think like a programmer. Choose something that is not too technical and that has all of the basic concepts covered(like loop, for, if, else, variables etc. etc.)

https://github.com/vhf/free-programming-books/blob/master/free-programming-books.md

The majority of the best programmer out there have studied nearly everything by themselves. If programming is the right thing for you, you don’t need a class. Maybe you will lose some time searching for the right sources, but if you will be patient and logical in the right way, you will surely make it.

If you want a nice overview in a paid book that doesn’t get too technical you should read IOS programming: big nerd ranch guide.

Haven’t played with google API myself, from having a quick look at it :

Seems like you have the inclusion src wrong (albeit it work with your src that has parameters appended … leave em be … ) also am I not seeing the initialization of the visualization.

You also have the entire JS code within 1 tag , separate it into 2 <script> tags.

Also the function is not defined in your code … how would you call the draw ?

You can decode it and render it safe to parse.

As has already been stated, the error message is given because of a server configuration setting.
Just take out everything before $maxlinks, and remove:

$time = explode(" ", microtime());
$time = $time[1] + $time[0];
$endtime = $time;
$totaltime = ($endtime - $begintime);

Then take out the echo statement at the end.

I have written only one small Java application before, but since I know some other languages, it is not difficult to adapt. Here is what I made:

public class BoxTest {
    public static void main(String[] args) {
        int nLowestVolumeId=-1;
        int nLowestVolume=-1;
        int nVolume=0;
        Box aBoxList[]=new Box[3];
       
        aBoxList[0]=new Box(5,6,1);
        aBoxList[1]=new Box(7,9,2);
        aBoxList[2]=new Box(5,4,3);
       
        for(int i=0;i nVolume){
                nLowestVolumeId=i;
                nLowestVolume=nVolume;
            }
        }
       
        System.out.println("Box "+nLowestVolumeId+" is the smallest one with volume "+nLowestVolume+".");
    }
}

Code: Select all
class Box {
    private int nHeight,nWidth,nDepth;
   
    public Box(int nSetHeight,int nSetWidth,int nSetDepth){
        nHeight=nSetHeight;
        nWidth=nSetWidth;
        nDepth=nSetDepth;
    }
   
    public int getVolume(){
        return nHeight*nWidth*nDepth;
    }
}

It does not set box width, height and depth to random values but that was not asked for anyway.

[SapnaVishwas]

This sounds quite alot like some homework Wink I will help you get started:

public class Box{

private int height, width, depth;

public Box(int height, int width, int depth){
}

You can use WITH NOFORMAT it’ll make sure whenever you hit the script new backup file will get created. Give it a try

Programming through a tablet is a very bad move. The standard Android development requires things that don’t exist on Android. If you want to program, you need a PC/laptop/Mac. A tablet/phone is not the right device. To program for Android you need Android Studio.
What API is asking you for a system build?

• Have you tried searching them(maven, builder) on Google?
• What are you referring to by saying that is just an IDE?

The standard library is enough for starting.

Searching a library/framework before knowing what to do is totally senseless. First you need to know what to do and after this you need to search the specific library/framework.
You are telling me that first you buy something totally random and then you decide what to do?

If I buy a hammer but then decide that I need to cook a pie, what can I use it for?
First you have an idea and then the realization. You can start by downloading Android Studio on your PC, searching what API, IDE mean and the difference between library and framework, searching what maven etc. etc. are and following a Java guide.

• A first chance exception of type ‘System.NullReferenceException’ occurred in MetaDatareader_with_Loop.exe
• A first chance exception of type ‘System.Reflection.TargetInvocationException’ occurred in mscorlib.dll

“…For applications / components which handle exceptions gracefully, first chance exception messages let the developer know that an exceptional situation was encountered and was handled.’

start with c++ because languages like c# and java kinda do everything for you. Which is really nice when you are really knowledgeable and just want to get stuff done, but if you use these languages that allow you to make things faster you won’t learn what’s really happening in your computer and you will get really confused later on, you’ll start thinking coding is all like

EmailClient client = new EmailClient();

. Maybe what you could try , and maybe this might hurt more than it helps is Learn a language like c++ first and do small projects to get the hang of it to learn about things like memory and pointers but at the same time if you have a real project you want to tackle move to c# and do it in that. That way you’ll build up confidence and also learn the really low level (as in close to the hardware level) stuff otherwise if you stick to c and c++ as a beginner you won’t get much done for a long time. One thing you must do is TEST TEST TEST, test code you find play around with it, that is one big mistake I made when starting is I would read code and understand it but I didn’t play around with it to really understand it well. I think C# is very good but I haven’t used it much. It has the lower level stuff like pointers and even inline assembly but it also has the more abstract stuff that java has and they are even talking about making .net multi-platform which means mac and Linux will be able to use it. One complaint, you have to type access modifiers (public,private,protected) on every bloody variable it seems redundant and stupid. Also make sure you know what the .net language is https://en.wikipedia.org/wiki/.NET_Framework#Architecture.

hint: the c# code you type gets turned into a common language that multiple languages share (vb,c#,f#) all get turned into this language which you don’t see , and then they get turned into something your computers processor knows how to use(assembly language).
Message me or post here if you don’t understand certain terminology. That is one of the hardest things when starting, the terminology. It will confuse you because there’s so many terms that have several different meanings in computers and in real life.

learning c# without any previous languages and all that they encapsulate is like trying to learn MMA without knowing striking, wrestling..

yes it can be done(nothing is impossible) but you are throwing yourself into the deep end and hoping to swim with sharks , your better off starting with c and working your way up, because all of the principals found in c# and java are a stepping stone coming from c and c++

its like going straight to quantum physics by skipping physics.

you really shouldn’t be handicapping yourself and confusing yourself and making it really difficult for yourself by going to c# because you will quickly become confused and lost and probably give up before going forward.

i have another question. how should I learn programming? I mean do i read the book in sequence and when I arrive at a new command etc, I test it by writing the code myself?

Or do I try to make a program and then consult some parts of the books to achieve what I have planned in my mind?

[SapnaVishwas]

Yes it was, but not in the original 3.5 framework. It was included only in 3.5 SP1.
