java programming help...

[tigabalm]

i have this for loop:

for (int i = 1; i <= 10; i++) {
System.out.println(i);
}

and want to:

Show a revision of this code that counts from 1 to 10 but skips the number 7. Don't use more than one loop.

i'd appreciate any help

thanks

how about:

for (int i = 1; i <= 10 && i != 7; i++)
{
System.out.println(i);
}

(That for loop is valid in C/C++ so I imagine it'd be fine in java as well, since they share a fairly similar syntax)

hmmm... ran it in dr. java and it goes up to 6 and stops...

thanks for the help tho, any other ideas to get it to just skip 7?

also, in boolean arthimetic, what does: || mean?

thanks

d'oh! I shoulda known that...simple mistake. I'll figure out another version for you...

anyway, in boolean algebra, you have three simple operators: AND, OR, and NOT (there's some others, but they're mixtures of these three)

In C-style languages, they're written like so:

AND is &&
OR is ||
NOT is !

voodoo u rock!!!

thanks so much!!!

are you allowed to use an 'if' statement inside the loop? I can't think of a way to do it otherwise...except maybe XOR'ing the numbers with 7, but that seems too ridiculous for this case...

if you're allowed to, then:

for (int i = i; i <= 10; i++)
{
if (i == 7)
{
continue;
}
else
{
System.out.println(i);
}
}

try

for (int i = 1; i <= 8 && i >=1; i++)
{
System.out.println(i);
}

[voodooA4]

that would only print the numbers 1 thru 8, no? unless I'm missing something...

[tigabalm]

well doesnt say that i cant use an if statement so i think we are good to go using voodoo's 2nd attempt.... one correction tho: i think its supposed to be:

int i = 1 and not: int i = i right?

THANKS GUYS!! really appreciate the help!

peace

[voodooA4]

no problem!

yep, it should be i = 1

[tigabalm]

another question:

if i'm supposed to evaluate a "boolean expression"

how am I supposed to do:

(x > 3) || z

thanks

peace

[voodooA4]

what do you mean 'evaluate it'...how so?
