first things first, the code you just posted isn't valid, as you can see from the red squiggly line
second - arrays are what we call "zero-indexed"
an array with a single item in it will have
length 1, but we access that item with array[0]
thus, array.length - 1Oh so by using [] we create an array yes ?
no
we access an array
remember, strings are actually
char[]
meaning all strings are arrays of charactersAh yea u are right it is an array of chars
Well, it isn't actually an array of chars, but it supports using the array syntax to access individual chars
Wired question can i access this way a bit of an int number ?
No. Ints don't support doing that
You can create a BitArray though
Ok thanks then i will read a bit about arrays and accesing stuff with [] brackets ^^
