Kotlin how to call method when all Boolean values are true in BooleanArray

Question

When all booleans are set to true and I run startProcess() then it should be true and I want to execute the onFinished() method. How do I do this?

private var completed: BooleanArray = booleanArrayOf(false, false, false, false)

fun startProcess() {
    completed.all { it -> callback.onFinished() }
}

you mean like: if (completed.all { it }) { callback.onFinished() }? — Roland

Put the all in an if-condition, e.g.:

fun startProcess() {
  if (completed.all { it })
    callback.onFinished()
}

from the linked all-reference:

Returns true if all elements match the given predicate.

Just use:

private var completed: BooleanArray = booleanArrayOf(false, false, false, false)
if (completed.all { it }) {
    callback.onFinished()
}
