java - Using 1 array to implement 2 for loop programs -

i trying make program every count of 2 changes value "open" or "1".

1-2-3-4-5-6-7-8-9-10

0-1-0-1-0-1-0-1-0-1 ** ** , after in every 3 count changes "open" or "1".

but if box "open" or "1". should "close" or "0".

and on 150 count.

my problem cant make output show 1 array.i have no problem doing if different array..help...

int[] box = new int [150]; int b = 0;     (a = 1; < box.length; a++) {     if (a % 2 == 0) {         box[b] = 1;     }         else {         box[b] = 0;     } } (int c = 1; c < box.length; c++) {     if (c % 3 == 0) {         if (box[b] == 1) {             box[b] = 0;         }         else {             box[b] = 1;         }     }     else {         box[b] = 0;     }     system.out.print(box[b]); //putting result here result in 001001001; } /*system.out.print(box[b]); -- putting outside results in zero.  

how can combine 2 for-loops 1 array? hope makes sense of you. different approach okay long loop , array used. output program should 011101011101 when 2 together...

this 2nd program did please check cause suppose add "0"'s , "1"'s after program executed want know how add it.putting inside loop loop 150 times

int box [] =  new int [150];  int ones= 0; int zero= 0;   for(int a= 0;a<box.length;a = a+2){ box[a]  = 1; for(int b =0;b<box.length;b = b+3){ if(box[b]==1){ box[b] = 0; zero++; } else{ box[b] = 1; one++; } system.out.print("no. of ones : " + one); /* putting here loops additions    150 , resulting thousands of ones */ } system.out.print(no. of ones: " + one); /* putting here result 0 , loops 150 counting thousands of 0 */ }  for(int =0; < box.length; i++){ system.out.print(box[i]); resulting 00111 - 150 /* next count 4 enough loops add 5 next , add 6 7 , 150 counts till hitting "open" or "1"? system.out.print("no. of one: " + sum); } -- putting here result 0 

thanks hope understand questions (theres lot of them)and i'm confused

you iterating on a , later on c assigning box[b]. , b remains 0, keep assigning box[0]. should assign box[a] , box[c].

in addition, should start loops 0, not 1.
