dealing with a boolean array (how to execute when all bool elements of the array is true?)

Rstar37

I'm having a problem writing my code. I wanted to execute a statement when more than one expression is true

boolean checking(){
  boolean myVar = false;
  boolean[] each = new boolean [8];
  for (int i = 0; i < 8; i++){
    if(i > 0){   //just a random expression
      each[i] = true;
    }
  }
  if(each[0] && each[1] && each[2] && each[3] && each[4] && each[5] && each[6] && each[7]){ //i need a better way to write that since the elements aren't always going to be 8 elements
    myVar = true;
  }
  return myVar;
}

this is a boolean function example (not the whole code)

GoToLoop

static final boolean checkAllTrue(boolean... bools) {
  for (boolean b : bools)  if (!b)  return false;
  return true;
}

thank you! it worked but i didn't get it, can't understand what : means in the for loop i guess i'll have to look that up, thanks!

thank you, and the way you've put return false; if an element is false solves the problem i had in the beginning so thanks very much!

Just to make things clearer between for ( : ) & for ( ;; ) loops, check it out checkAllTrue() w/ those 2 approaches together for easier comparison: :D

static final boolean checkAllTrue(boolean... bools) {
  for (boolean b : bools)  if (!b)  return false;
  return true;
}

static final boolean checkAllTrue(boolean... bools) {
  for (int i = 0; i < bools.length; ++i) {
    boolean b = bools[i];
    if (!b)  return false;
  }
  return true;
}

yeah I found out yesterday, it wasn't as hard as I thought. Thanks though :)
