for loops in kotlin code example

Example 1: kotlin for

for (i in 1..5) print(i) 			// "12345"
for (i in 5 downTo 1) print(i) 		// "54321"
for (i in 0 until 5) { 				// "01234"
     println(i)
}
for(i in 0 until list.size()){
    println(i)
}

Example 2: kotlin loop

for (i in 1..5) print(i)
-> 12345

for (i in 5 downTo 1) print(i)
-> 54321

for (i in 3..6 step 2) print(i)
-> 35

for (i in 'd'..'g') print (i)
-> defg

Example 3: for loop kotlin

val array = arrayOf(1, 3, 9)
for (item in array) {
    //loops items
}
for (index in 0..array.size - 1) {
	//loops all indices
}
for (index in 0 untill array.size) {
    //loops all indices
}
for (index in array.indices) {
    //loops all indices (performs just as well as two examples above)
}

Example 4: kotlin simple for loop

val names = listOf("Jack", "John", "Tim")
for(name in names){
	println(name)
}

Example 5: for loop kotlin

for (x in 0..10) println(x)

Example 6: kotlin for

val list = listOf("A", "B", "C")
for (element in list) {
 println(element)
}
