Beginners Java Question

March 30th · **Posted:** April 28th, 2011, 12:15 pm

Hey, I just started learning Java. I know this may be a stupid question but I already know how to write simple codes but is there a special program to run them? I use the eclipse IDE for coding and it has a run feature built in, do you also write the client that displays the program you wrote in Java? Here is one of the things I've written so far:

import java.util.Scanner;

class Calculator{
public static void main(String args[]){
Scanner Tyler = new Scanner (System.in);
double fnum, snum, answer;
System.out.println("Enter first number please.");
fnum = Tyler.nextDouble();
System.out.println("Enter second number please.");
snum = Tyler.nextDouble();
answer = fnum + snum;
System.out.println(answer);
}
}

Any help is appreciated. Thanks in advance.

I think this is what you mean? I program in c# so I use visual studio's but I dont think it supports Java programming.

Read my articles on learning how to program. They're based in Java. They got everything from what to use to some starting exercises.

Also, what do you mean by "write the client that displays the program you wrote in Java"?

I think he means like coding the thing that runs it, like Visual Studio's, so no you wouldnt.

Notepad++ is good, here's the website: www.notepad-plus-plus.org

You can't compile with it though, which I think he was asking about.

BlueJ. It's nice and simple, mentioned in the articles.

You can write what is called a driver program for other classes that you write, but it is not necessary unless you're doing a pretty big project. The driver program will create a new object of the class, and then use its methods to do things.

like:

public class driverClass
{
public static void main(String args[])
{
// Creating an object from the outside class file
otherClass foo = new otherClass(Parameters to constructor);

// Using one of the object's methods
foo.otherClassMethod();
}
}

Not sure if this is what you were looking for.

I have used JCreator and Netbeans as Java IDEs (of which I would recommend Netbeans). Make sure you download JDK, set its path (if necessary) in the IDE, and then you can compile and run your program. The same should apply to Eclipse.

camelCase would be also nice to learn

im sure your teacher would love it also even more is tabing your code "i know this is a forum"

Funny not. I'm so use to using camelCase that I use it not when saving files >.<
