The array at position 2 (the a) has not a real char value. So you must either:



// stepthrough the sentence array, get the first character
// of each string @ each index, and store...

Take a look at :
String (Java Platform SE 6)
and
Double (Java 2 Platform SE v1.4.2)

Here's an small example



try{

The first problem is that you operate on only two Arraylists. Both exist on the heap and not - like you may think - on the stack of the recursive calls. So after the the first three calls the...

Take a look at this:


public static interface IFunction<T> {

public void callFunction(T t);

}

private static IFunction<String> functionPointer = new IFunction<String>() {

Of course!!! You are right. There I was a little bit blockheaded:)

The problem is that the type of the value of the map is the wildcarded type Collection<EventHandler<? extends Event>>. To this type you can cast. When you write your method, it returns a concrete...

The program would be more convenient with different threads because the main thread stops every time you call server.accept() and stream.readUTF() Both methods stop the thread in which they are...

If you think of an OS like - for instance - a linux kernel which you can install on a hard drive. That's impossible. Java needs a VM and thus a basic OS. There is no way to evade these fact. But I...

You should use dynamic structures in this case:



public static void main(String[] args) {
ArrayList<Integer> inputVals = new ArrayList<>();
Integer temp = 0;
Scanner scanner = new...

I think so. I'm not a java networking expert and I dont know the best practices. Anyway here's a small example

Client impl:


package example.socket;

import java.io.DataOutputStream;

I strongly recommend to use Netbeans and JavaFX Tools when you want to develop GUIs in JavaFX. It's the native IDE for the framework.

JavaFX : JavaFX Tools
Netbeans: JDK 7 with NetBeans

I think that there exists no better language to do network programming like java. There exist several frameworks and standard specifications in any scale.

One of the core and basic technics are...

The two inputs results from the two constructor calls(you make the input operation in the constructor):
First:


public static void main(String[] args) {
calc_main c=new calc_main();


and...

The easiest way is to use Long.toBinaryString but I think that's not the purpose of the thread;)
If you have a JDK you can also check the source of the toBinaryString-method there you can find a...

The simplest way should be an extra break condition where you compare the parameters r and c to the row and column class var. But I'm not sure if you will go through the maze the right way then. ...

It happens at the exit of the maze. The exit condition doesnt work in this case becaus there is no wall.


char[][] test = new char[][] {
{ '*', '*', '*', '*', '*' },
{ '*', ' ', ' ',...

Regadring the interface view of multiple iheritance, you could use two or more interfaces, it will work.

Apart from that you can simulate multiple inheritance by declare and instaniate abstract...

Just a hint from a programmer, it's bad style to exit methods or return values in functions in more than one line. I didnt mean it in a bad way.

you make an assignment:

test = true means in java that you set the var test to true. And in java the assignment return its value so it allways true

Give (test == true) a try.

P.S.
In pascal...

I m not sure, cause i cannot debug the code due to the missing Recipse class(I know it's easy to implement but it's late;)

but I think the start value of currentRecipeNumber is wrong. You...

If you have Netbeans and JavaFX in your enviroment, then give that a try:


/*
* To change this template, choose Tools | Templates

*/
package ztest;
...

I dont know how to resovle this but if you have a newer versionof eclipse then give the marketplace a try. Search there for maven and you will find the plugin. if I remember right you can install it...

And be careful with encapsualting complex objects. Strings Integer and so are allways new initialized during assignments but check this for instance:



public static class...

The reason isin the questionMissed-method


for (int i = 0; i < questionWrong.length; i++) {

Check the functionality of postincrement and preincrement


return ++i;

will work
