Yea I know that method, but its hard to use the debugger. I
realized that java was discontinued with visual after 05. Thanks
for the input though.

I use netbeans but was wondering if anyone knew how to add a Java compiler to visual studio 2008?

Google Arrays.sort.

Just get the user input into an array, and use Arrays.sort( anArray),
then the anArray is sorted.

Use the mode (%) operator inside a for loop like so :


final int MAX = 100;
for(int i = 1; i < MAX; ++i){
if(i % 2 == 0 ) /* if i is a multiple of 2 */
{ //do stuff }
else if(i % 3...

First by Googling it! (http://leepoint.net/notes-java/data/arrays/70sorting.html)

Use the ? : operator.

>>note the question ask to reprint the array but without any repeating number

You can use the library sort method and then display the first element.
Compare it with its adjacent, if different...

It is converting it correctly. It just doesn't display the trailing 0's.

If you want to see the trailing 0's then you can use DecimalFormat...

Recursion is a bad idea here. But if this is what you want :

String str = "vertical";
printVertical(str);


and if the output should be :

v
e

make initCheck a static method. Do you know what the term static mean
in the context of programming?

Yea its right, sorry I am in c++ mode.

try :

Account accountSum = new Account();

Yea, sometimes, but IMO not all the times. It depends on the variable

Did you try it out?

Hint :

totals[die1 + die2]++;

should be :

totals[roll] = die1 + die2;

and make sure totals can hold up to 1000 dice roll information.

try posting your whole code

I think you want it to be this :

static float calcTaxes(float grossPay)
{
float netPay ;

if (grossPay <= 300)
netPay = (float) (grossPay - (grossPay * 0.15));

if (grossPay <= 450)

String msg = "place message here";
int cntr = 0;
for i = 0 to msg.size; increment i by 1
{
if msg.charAt(i) is equal to a white space or == ' ' then
increment cntr by 1;
}
...

1) Create a array, which represents a table.
2) use a for loop;


for(int i = 1; i != 5; i++)
myArrayTable[i] = 6*i; //say, myArrayTable is already declared.

Make use of functions. Try something like this


import java.util.Random;

class Main
{
static Random rand = new Random();

static void Print(Object ob){

It would help if you created a few function that returns either
lowercase, uppercase , number or a punctuations.

The in your randomLowercase(int len) function you can something like
for(int i =...

You could sort it and then check if the next element is the same and
work from there.

It works for me :

import java.*;


class Main
{
static void Print(Object ob){
System.out.print(ob);
}

Why is that again?

Yes. In fact thats very common, using 1d array as a mimic of a 2d.


final int ROW = 5;
final int COL = 5

char[] Letters = new char[ ROW * COL];

for(int i = 0; i < ROW * COL; i++)
...

Uhh, Nope. Where would you get that idea? Recursive functions are expensive. It should be only used when it simplifies a lot of complexity,
and has reasonable performance.

for(int i = 1; i <= 10; i++)
{
for(int j = 1; i <= i; j++)
System.print(j);

System.println();

}

I'm sorry my mistake, it should have been int getFact(int N);

Max is just any number. I just put it there so, as an arbitrary value.
Its not meant to be a full code, just enough to give you a...

create function;

void getFact(long N); //assume already created

for(int i = 0; i < MAX; i++)
Array[i] = getFact(i);

To share your problem, just post the problem. Ask specific question.
Maybe google it before you ask question, in which you might find the
answer.

total = distance / mpg * ppg + parking + tolls;

or

total = distance / ( mpg * ppg + parking + tolls ); ???

Try hitting alt+f6. Then click ok if a window pops up.

use for loop. It will be conceptually easier.

int F =5;
int R = 1;
for i = F to i >1 ; i--
{
R equals R times F;
F equals F minus 1;
}
