Write a Java program to convert an ArrayList of integers to an array of primitive int values. Write a Java program to convert an ArrayList to an array and remove null values in the process. Write a Java program to convert an ArrayList containing duplicate values into an array without duplicat...
In this tutorial, we will introduce how we can convert aList<Integer>toint[]in Java. We can see that both of them are of different data types that is ArrayList of Integers and the array of int. The former contains an object datatype i.e. Integer, and the latter is a primitive data...
