sortIncrease!

>int[][] twoD = twoDDoubleArray(...

What do you mean by this line? I could not understand it. is it supposed be a typdef or a class or method...?

Yes it is :
Two Dimension and the numbers are Double.

Hi everyone,
Yes, it is homework.
Nevertheless, I am stuck like a duck; how can I use:
public void sortIncrease (int [x]);
Or
public void sortDecrease (int [y]);
It does not work for me.
Any help is highly appreciated

What? What do you need help with?

Are you familiar with bubble sorting?

Here's sortIncrease:

public double[] sortIncrease(double[] array) {
for (int i = 0; i < array.length; i++) {
for (int j = 1; j < array.length; j++) {
if (array[j] < array[j - 1]) {
double temp = array[j - 1];
array[j - 1] = array[j];
array[j] = temp;
}
}
}
return array;
}

sortDecrease should be very easy for you now.. you only have to change one thing.

Post your code. You might need to make it static.

wow you're confused

public static void main(String args[]) {
double[][] twoD = twoDDoubleArray(4, 6, 47.0, 99.0);
printArray(twoD);
System.out.println("**********************");
double[][] twoD2 = twoDDoubleArray(2, 2, 47.0, 99.0);
printArray(twoD2);
System.out.println("**********************");
double[][] twoD3 = twoDDoubleArray(9, 5, 47.0, 99.0);
printArray(twoD3);
}

public double[] sortIncrease(double[] array) {
for (int i = 0; i < array.length; i++) {
for (int j = 1; j < array.length; j++) {
if (array[j] < array[j - 1]) {
double temp = array[j - 1];
array[j - 1] = array[j];
array[j] = temp;
}
}
}
return array;
}

No. Did you look at my code?

Kinda, it's just a method.

public class SortIncreaseDemo {
static public void main(String args[]) {
double[] array = new double[] { 3.45, 56.6, 230.3, 84.9, -43.4, 2.9 };
array = sortIncrease(array);
printArray(array);
}

static public void printArray(double[] array) {
for (int i = 0; i < array.length; i++) {
System.out.println(array[i]);
}
}

static public double[] sortIncrease(double[] array) {
for (int i = 0; i < array.length; i++) {
for (int j = 1; j < array.length; j++) {
if (array[j] < array[j - 1]) {
double temp = array[j - 1];
array[j - 1] = array[j];
array[j] = temp;
}
}
}
return array;
}
}

I think you need to go through some tutorials (http://java.sun.com/docs/books/tutorial/java/index.html)...

I thank you very much,

printArray(array);

}

double temp = array[j - 1];
array[j - 1] = array[j];
array[j] = temp;
}
}
}
return array;
}
static public double[] sortDecrease(double[] array) {
for (int i = 0; i < array.length; i++) {
for (int j = 1; j < array.length; j++) {

array[j - 1] = array[j];
array[j] = temp;
}
}
}
return array;

Your help is highly appreciated.

Now, I have to make the numbers come out of Random ()
Awesome. If you need more help, feel free to post. PS.. use the
code ([code][ /code]) tags when posting code.

I posted a method to sort a one dimensional array. You're trying to sort a
two dimensional array. What exactly are you trying to do? There are several
ways to sort a two dimensional array. Please specify. Also, please
use the code tags when posting code.

What do you mean by code tags?
Code Tags ( http://forums.dev-archive.com/misc.php?do=bbcode#code)
I would like to sort two dimenssional array.
Why? What does the two dimensional array consist of? doubles? I don't see
why you would need to do this.

Please post the assignment so I can get a better idea of what you are
trying to do.

You can notice that I have to call: twoD3 = sortIncrease(twoD3); Four times. But, hay; it works.
Still, I do not know how to implement Code[code\]
I need acctuale example.
I know myself. it is thick. does not take from the first time.

Thank you man.

Your question is logical one, maybe I missunderstand the assignment.
Now, I am after getting the info. from a file and then sort it.
The TME1 will be done.
Once again, thank you

That is right, but I have to use the same sortIncrease class that I have used so far.
i. e. there is a package and inheret...import...all in one jar file.

Ah, okay. We weren't on the right track. Okay, so we need to make 3 classes, Sort (this will be the main class), SortA, and SortB. SortA and SortB implement MyapiA and MyapiB, respectively. SortA and SortB have sort methods (from the interfaces) that generate an array of random numbers and sort them.

Try this, and post back if you have any trouble. If you're posting code please, please, please use the code tags (http://forums.dev-archive.com/misc.php?do=bbcode#code).

Good luck! :)

I failed
... I really don't know what to say. Okay. Next time you try to post code,
click on the # (underneath the color choice pull down menu) and post your code in there.

Hurrah! You posted in the code tags... yay. Okay, unfortunately, you're not
doing any thing in the assignment posted. Here's a basic outline. I'm leaving you to fill in the blanks.

Any way, I have to make two classes and two Interfaces, and but them in two packages one for classes and the other for Interfaces.
I have tried many ways to make use of :
public class sort {
static public void main(String[] args) {
(new sortA()).sortIncrease(randomDoubleArray);
(new sortA()).sortDecrease(randomDoubleArray);
(new sortB()).sortIncrease(randomIntArray);
(new sortB()).sortDecrease(randomIntArray);
}
}
But no luck.
I was able to get :
sortIncrease(rndDoubleArray); and sortDecrease(rndDoubleArray);
but, I failed to get (new sortA()).sortIncrease(rndDoubleArray);
Any advice?
Thanks in advance.

Now, how sortIncrease or sortDecrease will call rndArray?
Should I put:
Package Sort as the first line of each file and put the three files in this directory?
Thank you in advance.
