How can I read in a two dimensional array these file 10 10 10 255 0 0 23 45 92 48 74 83

Answer 1

Using FileReader class in nest for loop use split() method.

Answer 2

Can you be more specific please. Sorry if its bothers you.

Answer 3

Nested for loop

for(int i = 0; i < 4; ++i) {
for(int j = 0; j < 3; ++j) {
int x = arr[i][j];
}
}

Might have to do extra work to determine the size of the array, but that's the gist of it.

Answer 4

My for nest loop for the moment is
for( int i = 0; i<=50; i++)
{
for( int i2 = 0; i2 < 3; i2++)
ColorBalls[i][i2] = read.nextInt();
}}
// but it is throwing me an error, is that the proper way to read integer into a dimensional array?

Answer 5

My bad, jagged array element assignment in C# is:

ColorBalls[i, i2] = read.nextInt();

I presume nextInt() is returning a int?

Answer 6

Yes, but is not C# is java

Answer 7

Oh dang, my bad! Did you size the array appropriately?

int ColorBalls[][] = new int[50][3];

Also check to make sure there is a hasNextInt() before assignment. Maybe you're not reading what you expect to be?

Answer 8

When I try to read my file, it pops this error.
(Java.util.NoSuchElementException)

Answer 9

It means there is no nextInt(). If you used the look-ahead method hasNextInt I suggested this wouldn't occur.

Are you at least reading in some data? Do a step-by-step in debug. It may be that you're expecting N ints to be defined in the file but only N-1 exist.

Answer 10
