I suppose you need to ask for the number of grades and then continue looping in the for loop for those many times. Now, if you understand the for loop construct, initialise a counter to 1 and continue it to the number of grades, incrementing it once every time. Think …

Obviously, as it appears from your information as also from a google search over the topic, this is a bug in MySQL. And guess what the MySQL people accept this, actually this is bug # 25156. Many people have had this problem. Take a look [URL="http://bugs.mysql.com/bug.php?id=25156"]here[/URL] Edit : The MySQL …

Your query should be of the form : [code=sql]SELECT a.fruits FROM tableA a where a.fruit NOT IN (SELECT b.fruit2 from tableB b where b.fruit1 = 'apple') AND a.fruits != 'apple';[/code] This will work provided that 'apples' appear only in the fruit1 column of tableB. Don't expect this query to work …

You can use a do while loop to restrict no. of tickets entered from being negative or greater than 100. Ex: [code=java] do{ System.out.println("How many tickets ?"); atickets = keyboard.nextInt(); // check for input being in the range (not < 0 and not > 100) // if input is in …

@stephen84s : Yes but in this case, what happens if he inputs the number of adult tickets to be 110 ? You still ask him for the number of child tickets, which since he has already jumped the maximum count is wrong on our part. If he enters the no. …

My judgement here is that there was no infinite loop at all. When you are running a GUI based program you don't get to see any exceptions thrown by the JVM. Now, when your index counter was reaching 'size' then the JVM would have been throwing an exception which since …

According to the usage you mention, a stack would be more useful than a queue. Also take a look at this [URL="http://www.daniweb.com/forums/showthread.php?t=170140&highlight=crawler"]thread[/URL].

Java has an [URL="http://java.sun.com/j2se/1.3/docs/guide/awt/designspec/events.html"]Event Delegation Model[/URL]. In short this goes like this.

Event Listeners need to register to an Event Source so that for any events …

How are you creating the file ? If it is done with an absolute path then we need to see the code to tell you what might be going wrong. If it is created with a relative path in your program then the file certainly won't be created in the …

@masijade : You could easily have been a detective, you have the temparament and the ability to look into the slimmest of the crevices. ;)

You have already been offered help, only if you care enough to take it.

Also just to add to what masijade has explained very well and that too in a very concise manner, calling [icode]System.gc()[/icode] is not exactly considered a good programming practice. Also one question comes to mind here, how do you think you are going to [B][I]destroy[/I][/B] the object ?

Yes your approach here seems to be correct. From what I understand your program should be similar to a expression matching program - one that checks for the proper use of paranthesis, box brackets, angular brackets, braces in an expression. If you are not familliar with such a program I …

How are you going to arrange a list in 2D ? You would have to make a list of lists. With the first list just holding the heads of the list starting at that position. Something like this : |L1 -> List L1 follows... |L2 -> List L2 follows... |L3 …

For everything that they can be used. Typically for taking user input from console. PS : Ignore this, masijade has given you the world !!!!

How does the src directory contain a .class file ? That tells us that everything is [B][I]not[/I][/B] in the right place. On other thoughts, detail your problem if you want my solved threads count to go up, becuase I have a feeling I can solve this problem. It has all …

This gives me the feeling that this code is not written by you, can you tell us why so ?

Also if you are a beginner why use a fancy IDE at all ? Try coding by your hand using an editor, that would be better in the long run. Though some people use IDEs from the very beginning, it only results in you not knowing the language environment in …

No we certainly won't [I][B]do it[/B][/I] for you. It's your work you have to do it. Also put code tags to your code if you want somebody to take a look at it.

Because you ask for a fancy way, I give it to you. So suppose you want to allow multiple answers without much work you can do this : [code=java] Scanner input = new Scanner(); String response = ""; System.out.println("Do you want to continue ?" Yes/Y/No/N); response = input.nextLine(); do{ // …

Yes it is. I would have liked you to first having gone through the langauge documentation, since this is something that even the very first program requires you would have found this immediately and also learnt a few things with that. Search your question on the internet first if you …

You say you have read a lot of theory, why then don't you consider practicing what you learnt in theory. Say for example try the Abstract Classes, Interfaces, Classes, Inner Classes, Exceptions, Threading etc in examples that you might have read in theory. This way you would also be asserting …

This is because your system is not able to locate java. Here you have two options : 1. Open a command prompt window. Then write set path=%[I]JAVA_HOME[/I]% where [I]JAVA_HOME[/I] should be your path to the bin directory in your java installation. So, say for example you have Java installed in …

Actually the decision whether to throw an exception should be made wisely. The reason the throw and throws concepts exists is that that when a programmer feels incapable of handling an exception himself then he can delegate the condition to the next higher level in hope that the caller of …

[code=java] if(words.length <=3) [/code] This is wrong here, the length attribute would give you the length og the array, so for example if you have 5 words in the array, words.length will give you 5. Whereas you have to calculate the lenght of each word in the array. Here's how …
