processing/java: cannot invoke length() on the array type boolean[]

Question

Surprised that this wasn't already posted. I'm making a for loop, and its worked before but for some reason I can't find the length of a boolean array.

for(int z = 0; z < keyIsFound.length(); z++){
  //do something
}

Solution 1

For arrays, their lengths are fixed when we create them. If you want to get the length of any array, use .length.

Solution 2

.length = to get the length for arrays
.length() = to get the length of Strings

Solution 3

For array the length is a property - not a method. You have to write keyIsFound.length. Array is a fixed sized data structure when you create an array like -

int[] nums = new int[10];

You actually fixed it length too.
