Bitwise-inclusive-OR assignment Question-

C allows you to do this:


static int *line2 = NULL;

int failed;
failed |= (line2 == NULL);

nevermind...i figured it out :)

This is an escape sequence in C: \x7f
and is equivalent to: DEL

How would I represent this in Java as an octal character constant? and what is the logic behind it?

Thanks!

This is a stupid question, but I just don't know what the syntax would be if I changed the below variables to integers since int cannot invoke clone(). Help is greatly appreciated.


ll_point p =...

Ah, makes sense! Thanks dlorde, that took care of everything :)

hmmm...well, the only thing that I changed to your recommendation was to this:


private class E_list_comp implements Comparator<E_list_entry> {
public int compare(E_list_entry a,...

dlorde, thanks for your help again. Unfortunately when I changed it exactly as you said, I still receive the same warning message. Is there something else I need to do? Thanks!

I'm re-visiting this problem that I had, because I want to try and fix it the proper way. I've read more Java documentation, but really don't understand the warning that I receive and what I need to...

I will be looking into the ArrayList class in the book to get a better understanding of it.

In the mean time, I was pointed to a chapter in the book that might help me with getting rid of the...

The code is actually not from a book. This is pre-existing code originally from C. I'm just trying to work with the book to understand the syntax I need to use in order to fix the null pointer...

Apparantly I created an array of null pointers shown in the code below (which is obviously wrong). I'm reading a Java book and from what I gather, I need to go through that entire array and...

Oh believe me, I fully agree with your logic :) This is just pre-existing C code that has been given to me to convert into Java and I wanted to make sure I had the right idea of what was going on. ...

I'm trying to understand multiple goto's in a function. For the code below, if it goes to Return1 & does the line:

RetVal++; , would it then go back into the loop or would it proceed down to...

This is the function that is called within the other function:


static void e_map_loop(int *p1, int *p2)
{
int c;

for (c = 0; c < 48 - 2; c++)
{
*p2++ = p1[0] - p1[2];

Right right right...

I'm sorry in C, it would be:


private void e_map(int m1[48][48], int m2[48][48], lm_struct lms) {
int r;
int *p1, *p2;

for (r = 0; r < 48; r++)

This code is what I would do in C; however, Java gives two errors on the lines below with astericks. The error is: Type mismatch: cannot convert from int[] to int. What do I need to do in Java to...

I want to be able to sort an array within the function: sort_horiz. However, I'm not too familiar with implementing Comparable so I have a 2 errors that I need help with. Your suggestions are much...

Here's the relevant C code where it is assigned the start of an array:


static int list_count, horiz_list_count, verti_list_count;

dlorde, I'm coming further along with my conversions, and I stumbled upon a problem. Are you sure that the e_list[DM_N_E], *verti_e_list; part of the C code:


static struct e_list_entry
{

dlorde, thank you for the full explanations. It's much appreciated :)

I have another question based on your response. One of the functions that would utilize that class is this one:

I'm working on a project converting a bunch of C source files into Java ones. Doing okay so far with not much Java background. However, I'm stuck on this C code:

WOW! HanneSThEGreaT & GremlinSA...your projects are great! And Gremlin, that scrollbar is a perfect addition to the zoom feature :) I'm going to try and adapt these concepts into my project today;...

HanneSThEGreaT, that is a very clever program. Thank you! I'm trying to adapt something like that in my program; however, I'm having trouble. I have one PictureBox containing an image like your...

I knew it was something simple :) Thanks GremlinSA!
