Kotlin get function. Should be simple but I don't know how. Any assistance would be appreciated-CodePudding

Good day. So I came from java and now doing kotlin. What I want is very simple but I cant seem to get it right.

        var j: Int = 4
   
    for (i in 0 until movieList.size) {

        sum  = movieList.get(i)(j)
     //Answer from @lukas.j - It was as simple as sum  =  movieList[i].Weight

    }

I first tried it without the .get, then I saw it didn't understand what I was talking about so google told me to use .get.

This is probably a simple fix if someone can just show me how please. The array is a 2d array list.

I tried a suggestion and this error shows.

Another example of a different attempt with a different error.

Adding my array:

val movieList = ArrayList<MovieModel>().apply {


    add(MovieModel(190617, 182832, "Jcorp", 100,"Delivery done", "Delivery not done",""))
    add(MovieModel(190617, 182833, "Honda", 100,"No exceptions", "Exceptions",""))
    add(MovieModel(190617, 182832, "Everflu", 100,"100%", "50%",""))
    add(MovieModel(190617, 182832, "Panado", 100,"OK", "NO",""))
    add(MovieModel(190617, 182832, "Gheiters", 100,"Success", "Failed",""))
    add(MovieModel(190617, 182832, "John", 100,"Yes", "No",""))
    add(MovieModel(190617, 182832, "Everflu", 100,"false", "false",""))
    add(MovieModel(190617, 182832, "Everflu", 100,"false", "false",""))
    add(MovieModel(190617, 182832, "Everflu", 100,"false", "false",""))
    add(MovieModel(9190617, 182832, "Everflu", 100,"false", "false",""))
    add(MovieModel(190617, 182832, "Everflu", 100,"false", "false",""))
    add(MovieModel(190617, 182832, "Everflu", 100,"false", "false",""))
    add(MovieModel(190617, 182832, "Everflu", 100,"false", "false",""))
    add(MovieModel(190617, 182832, "Everflu", 100,"false", "false",""))
    add(MovieModel(190617, 182832, "Everflu", 100,"false", "false",""))
    add(MovieModel(190617, 182832, "Everflu", 100,"false", "false",""))
    add(MovieModel(190617, 182832, "Everflu", 100,"false", "false",""))
    add(MovieModel(190617, 182832, "Everflu", 100,"false", "false",""))
    add(MovieModel(190617, 182832, "Everflu", 100,"false", "false",""))
    add(MovieModel(10, 182832, "Everflu", 100,"false", "false",""))
    add(MovieModel(10, 182832, "2010", 100,"false", "false",""))
    add(MovieModel(10, 182832, "2010", 100,"false", "false",""))
    add(MovieModel(10, 182832, "2010", 100,"false", "false",""))
    add(MovieModel(10, 182832, "2010", 100,"false", "false",""))
    add(MovieModel(10, 182832, "2010", 100,"false", "false",""))
    add(MovieModel(10, 182832, "2010", 100,"false", "false",""))
    add(MovieModel(10, 182832, "2010", 100,"false", "false",""))

 }

Movie model:

    package com.dispatch.tripsheet

class MovieModel(
    var WOrder: Int,
    var DElNote: Int,
    var Company: String,
    var Weight: Int,
    var Button1: String,
    var Button2: String,
    var tvdone: String

    )

I would suggest to use a data class instead of a class:

data class MovieModel(
  var WOrder: Int,
  var DElNote: Int,
  var Company: String,
  var Weight: Int,
  var Button1: String,
  var Button2: String,
  var tvdone: String
)

Creating the list can be done with listOf:

val movieList = listOf(
  MovieModel(190617, 182832, "Jcorp", 100, "Delivery done", "Delivery not done", ""),
  MovieModel(190617, 182833, "Honda", 100, "No exceptions", "Exceptions", ""),
  MovieModel(190617, 182832, "Jcorp", 100, "Delivery done", "Delivery not done", "")
)

And you can get and set the weight like this:

val movie = movieList[0]
println(movie.Weight)   // Output: 100

movie.Weight = 125
println(movie.Weight)   // Output: 125

CodePudding user response：

The syntax you're looking for is (see Indexed access operator):

movieList[i][j]

Alternatively, you may use the get syntax:

movieList.get(i).get(j)

However this feels unnecessarily verbose.
