In my example, you can simply replace i by AtomicInteger and make your operations thread safe. Pitfall number four occurs when you have some parallel operations messing with i. In my example you can do it easily by replacing if by when. You will have to either delegate step calculation to additional function which is even worse, or rewrite everything. You won’t be able to do it with for anymore. Pitfall number three: Suppose you want a more complicated behavior and need three different steps instead of two. You do it in one place, but forget to do in another and now you have two iterations with different number of steps. Pitfall number two: For some reason, you want to change the behavior of your dynamic step.
You should obviously never do it, but changing the increment is the first step in this direction. Pitfall number one: You accidentally or intentionally changing i somewhere inside your loop.
The problem arises when you have a large code. Var size = 0 //using while loop while ( size ) " )įor ((position, i) in arraysNew. first, we using while loop we create a variable that value is zero first and after working with loop this value will increase. Now we use some practices with the loop that's print all the value in an array. we don't put the same type of data in the array. Val arraysNew = listOf( 1, "shudipto ", 2.5, 0.234, "Trafder ", false)Ĭode analysis- you might notice that in this array we insert Now add an another variable and initialize it by calling listOf() If we don't define this array with a data type then we can insert any type of data type in it. Note: here Array(5) it indicates that it's size is 5. Now currently our arrays variable has only one index and index position is 0 now add some other index and also print an index for checking. Let's start- we declare a variable and name arrays and assign with Array. The array is really helpful for saving the collection of data.
In this post, we are going to learn about Array.
