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...
Ints.toArray(ListOfIntegers)is a part of thecom.google.common.primitives.Intspackage that takes our list as an argument and provides us with the array of ints. importcom.google.common.primitives.Ints;importjava.util.ArrayList;importjava.util.List;publicclassMain{publicstaticvoidmain(String[]ar...
