loop for kotlin code example
Example 1: 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 2: 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 3: kotlin simple for loop
val names = listOf("Jack", "John", "Tim")
for(name in names){
println(name)
}
Example 4: kotlin loop
var bubbles = 0
while (bubbles < 50) {
bubbles++
}
println("$bubbles bubbles in the water\n")
do {
bubbles--
} while (bubbles > 50)
println("$bubbles bubbles in the water\n")
repeat(2) {
println("A fish is swimming")
}
-> 50 bubbles in the water
49 bubbles in the water
A fish is swimmingA fish is swimming
