Cast operator in java is used to convert one data type to other.Examplepublic class Sample {    public static void main(String args[]) {       double d = 20.3;       int i = (int)d;       System.out.println(i);    } }Output20

The sort(int[] a, int fromIndex, int toIndex) method of the java.util.Arrays class sorts the specified range of the specified array of integer value into ascending numerical order. The range to be sorted extends from index fromIndex, inclusive, to index toIndex, exclusive.Exampleimport java.util.Arrays; public class ArrayDemo {    public static void main(String[] args) {       int iArr[] = {3, 1, 2, 18, 10};       for (int number : iArr) {          System.out.println("Number = " + number);       }       Arrays.sort(iArr, 0, 3);       System.out.println("int array with some ...

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 instanceof operator is used only for object reference variables. The operator checks whether the object is of a particular type (class type or interface type).Examplepublic class Test {    public static void main(String args[]) {       String name = "James";       boolean result = name instanceof String;       System.out.println(result);    } }Outputtrue

The sort(int[]) method of the java.util.Arrays class sorts the specified array of integer values into ascending numerical order.Exampleimport java.util.Arrays; public class ArrayDemo {    public static void main(String[] args) {       int iArr[] = {2, 1, 9, 6, 4};       for (int number : iArr) {          System.out.println("Number = " + number);       }       Arrays.sort(iArr);       System.out.println("The sorted int array is:");       for (int number : iArr) {          System.out.println("Number = " + number);       }    } }Output Number = 2 Number = 1 Number = 9 Number = 6 Number = 4 The sorted int array is: Number = 1 Number = 2 Number = 4 Number = 6 Number = 9

The conditional operator is also known as the ternary operator. This operator consists of three operands and is used to evaluate Boolean expressions. The goal of the operator is to decide; which value should be assigned to the variable. The operator is written as:variable x = (expression)? value if true: value if falseExamplepublic class Test {    public static void main(String args[]) {       int a, b;       a = 10;       b = (a == 1) ? 20: 30;       System.out.println("Value of b is: " + b);       b = (a == 10) ? 20: 30;       System.out.println(“Value of b is: " + b);    } }OutputValue of b is: 30 Value of b is: 20

A regular expression in Python is a set of characters that allows you to use a search pattern to find a string or a group of strings. These are used within Python using the re package. To match the end of the string in Python by using a regular expression, we use the following regular expression -^/w+$ Here, $ implies the start with. /w returns a match where ... Read More

The left operand value is moved right by the number of bits specified by the right operand.Example: A >> 2 = 15 means 1111.

The left operand value is moved left by the number of bits specified by the right operand.Example: A

This article will help you understand all about Bitwise Zero Fill Right Shift Zero Operators in Java. Note that Bitwise Zero Fill Right Shift Zero Operator is same as Bitwise Zero Fill Right Shift Operator. Before understanding right shift operators, let us revise about Operators. OPERATORS In computer programming we often need to perform some arithmetical or logical operations. In such circumstances, we need operators to perform these tasks. Thus, an Operator is basically a symbol or token, which performs arithmetical or logical operations and gives us meaningful result. The values involved in the operation are called Operands. In this ... Read More
