List<String>MyList=Stream.of("Value1","Value2","Value3").collect(Collectors.toCollection(ArrayList::new)); 4. Creating an Unmodifiable List 4.1. Using Collections The collection class provides various methods that can operate on a collection to return a list of elements. One such method isC...
It is relatively easier to initialize a list instead of anArrayListin Java with initial values in one line. However, if needed, it can be converted to anArrayList. The below example illustrates both ways. importjava.util.*;publicclassMain{publicstaticvoidmain(String[]args){// Initialize a li...
One such method isArrays.asList(). This method allows you to create an ArrayList and fill it with elements in a single line of code. Here’s an example: ArrayList<String>names=newArrayList<String>(Arrays.asList("John","Alice"));System.out.println(names);#Output:#[John,Alice] ...

The List<T> interface is the generic equivalent of the ArrayList class in C# and uses an array that can be dynamically increased as per one’s requirements. As the capacity of a list can be increased to two billion elements on a 64-bit system, you can implement your custom synchronization...
