Check out the following example, which converts a map into a list. Example 1: packagemaptolist;importjava.util.HashMap;importjava.util.List;importjava.util.Map;importjava.util.stream.Collectors;publicclassMapToList{publicstaticvoidmain(String[]args){Map<Integer,String>M2L=newHashMap<>();M2L....
In this example, we have a list of integers that we want to sort in ascending order. We use theCollections.sort()method to sort the list, and then print the sorted list to the console. The output shows the list sorted in ascending order. This is a basic way to sort a list in Jav...
If the value satisfies the condition, it is added to the res list with add method. The next code example uses the filter method. Main.java import java.util.List; void main() { var vals = List.of(-3, 0, 1, -1, 2, 5, 12, 8, -7, -2, 11); var res = vals.stream()....
In Java, ArrayList can hold objects of wrapper classes like double, integer, and string. We then add elements to the ArrayList using the add() method. Firstly, we added a string value to our ArrayList, then a double value, integer, and float, respectively. We can also replace an element...

add("Chaitanya"); add("Rahul"); add("Aditya"); }}; System.out.println(names); } } 5. Using Java 9+ List.of() and new ArrayList In Java 9 and later, you can useList.of()to create an immutable list and then pass it to theArrayListconstructor if you need a mutable list. ...
Stream (java.util.stream)in Java is a sequence of elements supporting sequential and parallel aggregate operations. There is no function for adding a value to a specific index since it’s not designed for such a thing. However, there are a couple of ways to achieve it. ...
In Scala, lists are immutable data structures in which adding new elements is not allowed. So, here we will solve this problem that is generally done in functional programming paradigms. To add elements to a listthere are two methods,
Java append to file tutorial shows how to append to a file in Java. We use FileWriter, FileOutputStream, Files, RandomAccessFile, Google Guava, and Apache Commons IO.
