Trying to make an Arraylist out of my obbjects, using the ArrayList of below code .
Here my code is :-

 var i = 1.0
 var list: ArrayList<Any> = ArrayList()
 while (i <= n) 
 intPerMonth = P * R
 P = P - (e - intPerMonth)
 Log.e("TAG", "Month -> " + i.toInt())
 Log.e("TAG", "Interest per month -> " + Math.round(intPerMonth))
 Log.e("TAG", "Principal per month -> " + Math.round(e - intPerMonth))
 Log.e("TAG", "Balance Principal -> " + Math.round(P))
 Log.e("TAG", "***************************")

 list = arrayListOf(
 i.toInt(),
 Math.round(intPerMonth),
 Math.round(e - intPerMonth),
 Math.round(e - intPerMonth),
 Math.round(P)
 )
 i++
 Log.e("myArray", list.toString()) // this list.toString() is my output

 

Output of this Program is

E/myArray: [1, 10, 79, 79, 921]
E/myArray: [2, 9, 80, 80, 842]
E/myArray: [3, 8, 80, 80, 761]

but i want this type of list:-

[(1,10,79,79,921),(2,9,80,80,842),(3,8,80,80,761)]

So it looks like you want a list of lists? Try creating an inner list in every iteration that you then add to your list, like this:

var i = 1.0
var list: ArrayList<Any> = ArrayList()
while (i <= n) 
 intPerMonth = P * R
 P = P - (e - intPerMonth)
 Log.e("TAG", "Month -> " + i.toInt())
 Log.e("TAG", "Interest per month -> " + Math.round(intPerMonth))
 Log.e("TAG", "Principal per month -> " + Math.round(e - intPerMonth))
 Log.e("TAG", "Balance Principal -> " + Math.round(P))
 Log.e("TAG", "***************************")

 var innerList = arrayListOf( // create a different list here
 i.toInt(),
 Math.round(intPerMonth),
 Math.round(e - intPerMonth),
 Math.round(e - intPerMonth),
 Math.round(P)
 )
 list.add(innerList) // add the inner list to your list
 i++

Log.e("myArray", list.toString()) // this prints the new list of lists
