To remove an element from a Queue, use the remove() method.First, set a Queue and insert some elements −Queue q = new LinkedList(); q.offer("abc"); q.offer("def"); q.offer("ghi"); q.offer("jkl"); q.offer("mno"); q.offer("pqr"); q.offer("stu"); q.offer("vwx");Remove the first element −System.out.println("Queue head = " + q.element()); System.out.println("Removing element from queue = " + q.remove());The following is ...

To create a Sorted Set, firstly create a Set −Set s = new HashSet();Add elements to the above set −int a[] = {77, 23, 4, 66, 99, 112, 45, 56, 39, 89}; Set s = new HashSet(); try {    for(int i = 0; i < 5; i++) {   ... Read More

The method java.util.Stack.empty() is used to check if a stack is empty or not. This method requires no parameters. It returns true if the stack is empty and false if the stack is not empty.A program that demonstrates this is given as follows −Example Live Demoimport java.util.Stack; public class Demo { ...

Use the containsValue() method to check for the existence of a value. First, create a IdentityHashMap −Map m = new IdentityHashMap();Add some elements −m.put("1", 100); m.put("2", 200); m.put("3", 300); m.put("4", 150); m.put("5", 110); m.put("6", 50); m.put("7", 90); m.put("8", 250); m.put("9", 350); m.put("10", 450);Now check for the existence of a value ...

The location of an element in an ArrayList can be obtained using the method java.util.ArrayList.indexOf(). This method returns the index of the first occurrence of the element that is specified. If the element is not available in the ArrayList, then this method returns -1.A program that demonstrates this is given ... Read More
