For Loop in kotlin [closed]

Question

I am new in Kotlin, Please help me in achieving this.

int number[] = {5,4,1,3,15}  for(int i = number.length; i > 0; i--) {    Log.e("number", number[i]) } 

Answer 1

Try this

syntax of for loop in Kotlin is:

for (item in collection) {     // body of loop } 

body

for (item: Int in ints) {     // body of loop } 

SAMPLE CODE

for (i in 0..5) {         println(i) // 0,1,2,3,4,5   --> upto 5 } 

OR

 for (i in 0 until 5) {         println(i) // 0,1,2,3,4    --> upto 4  } 

for loop in array

var arr = arrayOf("neel", "nilu", "nilesh", "nil")      for (item in arr)     {         println(item)     } 

iterate through an array with an index.

 var arr = arrayOf("neel", "nilu", "nilesh", "nil") for (item in arr.indices) {          // printing array elements having even index only         if (item%2 == 0)             println(language[item])     }

and this also for loop in Kotlin

Read Control Flow Structure in Kotlin .

for (item in collection) print(item)

for loop iterates through anything that provides an iterator. This is equivalent to the foreach loop.

The body can be a block.

for (item: Int in ints) {     // ... } 

Try with

val number = arrayOf(5, 4, 1, 3, 15)      for (i in 0 until number.size)     {         Log.e("NUMBER", number[i].toString())     }
