In C++ programming, initializing an array within a constructor is a common practice, especially in object-oriented design. Consider a class named DataContainer that encapsulates an integer array. Our goal is to ensure this array is initialized appropriately when an object of the class is created....
Initialize a static array publicclassMain {staticInteger[] integerArray;static{ integerArray =newInteger[] {newInteger(1),newInteger(2) }; }publicstaticvoidmain(String args[]) {for(inti = 0; i < integerArray.length; i++) { System.out.println(integerArray[i]); } } }...
Optionally, theArrayListconstructor takes an optional parameterinitialCapacity. It must be a positive integer and denotes the initial capacity of the list. The initial capacity represents the number of elements that theArrayListcan hold without resizing its internal array. The following example creates an...

To directly initialize a HashMap in Java, you can use the put() method to add elements to the map. Here's an example: Map<String, Integer> map = new HashMap<>(); map.put("key1", 1); map.put("key2", 2); map.put("key3", 3); This creates a HashMap with three key-...
The following example of the init() method initializes a counter by creating a public integer variable called thisMany:public class myServlet extends HttpServlet { int thisMany; public void init (ServletConfig config) throws ServletException { super.init(config); thisMany = 0; } }...
