A switch statement allows a variable to be tested for equality against a list of values. Each value is called a case, and the variable being switched on is checked for each case.Syntaxswitch(expression) { case value : // Statements break; case value : // Statements break; // You can have any number of case statements. default : // Statements }The following rules apply to a switch statement −The variable used in a switch statement can only be integers, convertible integers (byte, short, char), ...

The sort(Object[]) method of the java.util.Arrays class sorts the specified array of Objects into ascending order according to the natural ordering of its elements.Exampleimport java.util.Arrays; public class ArrayDemo { public static void main(String[] args) { Object ob[] = {27, 11, 44}; for (Object number : ob) { System.out.println("Number = " + number); } Arrays.sort(ob); System.out.println("The sorted Object array is:"); for (Object number : ob) { System.out.println("Number = " + number); } } }OutputNumber = 27 Number = 11 Number = 44 The sorted Object array is: Number = 11 Number = 27 Number = 44
The fill(int[] a, int fromIndex, int toIndex, int val) method of the java.util.Arrays class assigns the specified int value to each element of the specified range of the specified array of integers. The range to be filled extends from index fromIndex, inclusive, to index toIndex, exclusive.(If fromIndex==toIndex, the range to be filled is empty.)Exampleimport java.util.Arrays; public class ArrayDemo { public static void main(String[] args) { int arr[] = new int[] {1, 6, 3, 2, 9}; System.out.println("Actual values: "); for (int value : arr) { System.out.println("Value = ...

In this tutorial, we will be discussing a program to understand how to convert a class to another class type in C/C++.Class conversion can be done with the help of operator overloading. This allows data of one class type to be assigned to the object of another class type.Example Live Demo#include using namespace std; //type to which it will be converted class Class_type_one { string a = "TutorialsPoint"; public: string get_string(){ return (a); } void display(){ cout
In this tutorial, we will be discussing a program to understand how to find the sum of elements of a vector using STL in C++.To find the sum of elements of a given vector, we would be using the accumulate() method from the STL library.Example Live Demo#include using namespace std; int main(){ //defining the vector vector a = { 1, 45, 54, 71, 76, 12 }; cout
The fill(object[] a, int fromIndex, int toIndex, object val) method of the class java.util.Arrays assign the specified Object reference to each element of the specified range of the specified array of objects. The range to be filled extends from index fromIndex, inclusive, to index toIndex, exclusive. (If fromIndex==toIndex, the range to be filled is empty)Exampleimport java.util.Arrays; public class ArrayDemo { public static void main(String[] args) { Object arr[] = new Object[] {1.2, 5.6, 3.4, 2.9, 9.7}; System.out.println("Actual values: "); for (Object value : arr) { System.out.println("Value ...

The toArray() method of the java.util.ArrayList class returns an array containing all of the elements in this list in proper sequence (from first to the last element).This acts as a bridge between array-based and collection-based APIs.Exampleimport java.util.ArrayList; public class ArrayListDemo { public static void main(String[] args) { ArrayList arrlist = new ArrayList(5); arrlist.add(20); arrlist.add(40); arrlist.add(10); arrlist.add(15); arrlist.add(25); for (Integer number : arrlist) { System.out.println("Number = " + number); } Object[] ...

The contains(Object) method of the java.util.ArrayList class returns true if this list contains the specified element.Exampleimport java.util.ArrayList; public class ArrayListDemo { public static void main(String[] args) { ArrayList arrlist = new ArrayList
JRE is Java Runtime Environment and is the machine-specific implementation of JVM. It contains libraries like rt.jar, class loaders etc which are used by JVM.
In this tutorial, we will be discussing a program to understand how to find common elements between two vectors using STL in C++.To find the common elements between two given vectors we will be using the set_intersetion() method.Example Live Demo#include using namespace std; int main(){ //defining the vectors vector vector1 = { 1, 45, 54, 71, 76, 12 }; vector vector2 = { 1, 7, 5, 4, 6, 12 }; sort(vector1.begin(), vector1.end()); sort(vector2.begin(), vector2.end()); cout
