basically i have this variable
boolean[] firstClass = new boolean[11];
I need to store the numbers 1,2,3,4,5 in that and in another
boolean[] economy = new boolean[11];
I need to store the numbers 6,7,8,9,10 in that with a for loop

for (int i = 0; i < 5; i++) {
firstClass[i] = true;
economy[i + 5] = true;
}
the for loop iterates 5 times, and in each iteration, the value of i increments by 1. The value of i is used to store true in the firstClass array at index i and in the economy array at index i + 5.
stable merlin
thanks i will try it
stable merlin
for (int i = 0; i < 5; i++) {
firstClass[i] = true;
economy[i + 5] = tru...
also the directions say i have to make it false, so i will do that
how would I print that out
the numbers
right now i have
for(int x=0;x<=4;x++){
System.out.println(firstClass[x]);
}
to print it out
but it just prints out
false
false
false
idle linden
well. didn't you just make them false
stable merlin
yes
idle linden
god why is it in comic sans
first off; you shouldn't have 2 arrays
you should just have one, of size 10
stable merlin
ok
onyx shell
for (int x = 0; x <= 4; x++) {
if (firstClass[x]) {
System.out.println(x + 1);
}
}
can u try that
idle linden
please don't spoonfeed
onyx shell
i didn't
stable merlin
its fine
onyx shell
not the same code
idle linden
you literally did. that's what spoonfeeding is
onyx shell
not matter
idle linden
you should just have one, of size 10
so from this; as the prompt states, seats 1-5 are for first class, 6-10 are economy
you can represent all that as a single array
stable merlin
ok i did that
idle linden
do you have your input/output system setup
stable merlin
yes
stable merlin
ok

man im just startin out
idle linden
yeah ik
onyx shell
hello
idle linden
oh please don't
onyx shell
what should i dont
idle linden
the boolean array can be used to check if a certain seat x is reserved by using array[x]
