Let’s see a example for how to use Hashtable in java programs. import java.util.Hashtable; import java.util.Iterator; public class HashtableExample { public static void main(String[] args) { //1. Create Hashtable Hashtable<Integer, String> hashtable = new Hashtable<>(); //2. ...
// Declares String reference variable str1 and str2 String str1; String str2; // Assigns the reference of a String object "Hello" to str1 str1 = new String( "Hello World !!" ); // Assigns the reference stored in str1 to str2 str2 = str1; System.out.println( str1 ); //Hel...
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-...

Of course, there are a number of ways to create memory leaks in Java. For simplicity we will define a class to be a key in aHashMap, but we will not define theequals() and hashcode()methods. A HashMap is ahash tableimplementation for the Map interface, and as such it defines the...
To convert an array to a Set in Java, you can use the Arrays.asList() method to create a List from the array, and then use the List.toSet() method to create a Set from the List. Here is an example of how to convert an array to a Set: import java.util.Arrays; import java....
