i just need one like if a is greater than or equal to 70 it will stop ..

if you mean the condition at line 40 then it's because if any of the condition remains true then it will continue to loop (if any of the variables is less than or equal to 70)

are you familiar with using a runnable interface so you can continuously repaint the object?

on a side note... it might be my laziness talking but if it were me I'd just use several images of pacman pertaining to a direction instead of writing code to draw the shapes. Then I'd call and paint a selected image depending on which key is triggered

Re: Duplicates

the first one checks for order if it's greater than, less than or equal to the object it is being compared with and returns a specified value given the result

the equals method checks for the equivalence of the objects with their values

the == works similarly as the equals method but it also checks wether the references to the object are equal

my opinion is since you only need to check if the list have duplicates the first option wouldn't be necessary
if the list contains elements that have primitive data types use '==' else use equals method
you can test each option and see for yourself which is appropriate, if you have doubts you can always check the API

did you try printing out the contents of the array to see if anything is off or increasing the size of the puzzle by either a column or a row or both by all sides of the puzzle to see if it makes a difference in the results
for example put a new line of text at the beginning so p from 'develop' will be found at the second row

you could also try to minimize the puzzle and print out the contents and results to scope out where the problem occurs

Re: Problem with page size adjustment (HTML, CSS)

ok then same answer as before, put every element in a division
it'll look something like this

        <body>
            <div id = "main">
                <div id = "logo">...</div>
                <div id = "text">...</div>
                ...
            </div>
        <body>

where in its css the width of main is constant e.g. 900px

Re: Problem with page size adjustment (HTML, CSS)

what I meant by fixed width is the width attribute of the division has a set value i.e. width:700px; which you can freely change or do you mean that it should have dynamic changes whenever the user zooms or scrolls?

Do i have to start a new discussion whenever a question is solved?

yes

How is it?...

The for loops at the menu function is unnecessary, you could simply pass the value for the the stucture index from the main function

Re: How to remove one string from the whole ArrayList

zeroliken 79 Nearly a Posting Virtuoso

for(int i = 0; i < list1.size() - 1; i++){
        if(list1.get(i).compareTo(list2.get(i)) == 0){
            list1.remove(list2.get(i));
        }
    }

once an element is removed from either list their sizes will be different from the other. So you can't compare the remaining elements of a list with the others original position

You could use a nested loop to check if a value from a list is present with every element from the other

Re: ClassBook HELP.

Let's start with the basics then, you need to learn a few things first before you start coding
I suggest you head over over to the java tutorials and read about classes, to learn the gist of things, here's a link
http://docs.oracle.com/javase/tutorial/java/javaOO/index.html
Once you have a clear understanding we can start tackling the coding part, feel free to ask questions here if you get stuck somewhere

Re: Machine Language Operating Systems

zeroliken 79 Nearly a Posting Virtuoso

I currently have a subject titled "Introduction to Computer Organization and Machine-Level Programming" which focuses on Assembly language on 32 bit systems with Nasm as the compiler and uses Intel style syntax.

Having studied first high level languages first like C and Java I struggled a bit with Assembly which requires a lot of instructions to perform simple tasks which only takes a few lines for high languages to perform. Despite this unlike the high level lang I get to actually view the compute's memory storage and allocation for the program which answers some of the questions I'd have during the first years of my CS course

Now for other OS, correct me if I'm wrong as I recall Windows was built using C and also in Assembly(but the latter's only minimal)

Re: pointer

and i am using pointer 'root' in main() (as shown in code i have posted). but here i cant compare it to NULL

huh? you can compare it to NULL, the if condition in your code won't be met since you allocated memory to it... as explained before

in a bst comparing the node to null is only used to check if it is allocated successfully, I don't see a reason to force it to be NULL

now with arrays it will look something similar to this:

char GuessColor[10];
char color[10][10] = {"blue", "green", "red", ...};
for(i = 0; i < strlen(color[i]); i++)
    if(GeneratedNumber == i)
        strcpy(GuessColor,color[i]);

printf("%s", GuessColor);

simple

zeroliken 79 Nearly a Posting Virtuoso

12 Years Ago

by "assign" I mean it's more on conditions where a string variable color will get it's value from the generated number using if-else statements
example would look something like this:

if(numbergenerated == 1)
    color = "blue";
else if(numbergenerated == 2)
    color = "red";

but seriously take the array advice it's gonna lessen the code cluster

zeroliken 79 Nearly a Posting Virtuoso

12 Years Ago

you could (well not literally assign but the use of conditions),though that's gonna be a lot of if-else statements
using an array and looping through the indexes will simplify this

zeroliken 79 Nearly a Posting Virtuoso

12 Years Ago

even i will just use the colors? not the colors but the words red,blue,green,yellow,white,pink only

if those are the only words you'd need then it's more easy to store them in an array and using the rand() function to generate a number, check the word whose index matches the generated number and retrieve it

zeroliken 79 Nearly a Posting Virtuoso

12 Years Ago

but can it be used without using words from a file? just only using turbo c itself.

either create an array containing them or randomly choose letters to fill a string

zeroliken 79 Nearly a Posting Virtuoso

12 Years Ago

the only randomizing funtion for C I know is exclusive for integers only.
What you could do is create and store the words in an array or file then use the rand function to generate a number, the word whose index matches the number will be retrieved

zeroliken 79 Nearly a Posting Virtuoso

randomizing in words

still vague, can you tell if you meant
generate letters randomly to form a word,
retrieve words randomly from a file or array,
or something else??
