Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects", which may contain data, in the form of fields, often known as attributes; and code, in the form of procedures, often known as methods. For example, a person is an object which has certain properties such as height, gender, age, etc. It also has certain methods such as move, talk, and so on.ObjectThis is the basic unit of object-oriented programming. That is both data and function that operate on data are bundled as a unit called an object.ClassWhen you define a class, you define a blueprint for ... Read More

C++ is a programming language developed by Bjarne Stroustrup in 1979 at Bell Labs. C++ is regarded as a middle-level language, as it comprises a combination of both high-level and low-level language features. It is a superset of C, and that virtually any legal C program is a legal C++ program. C++ runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX.It is a language that is − Statically typed − A programming language is claimed to use static typing when type checking is performed during compile-time as opposed to run-time. Compiled − A compiled ...

It is a bitwise right shift operator. The bit pattern is shifted towards right by number of places stipulated by operand on right. Bits on left are set to 0For example a=60 (00111100 in binary), a>>2 will result in 15 (00001111 in binary)>>> a=60 >>> bin(a)result #39;0b111100' >>> b=a>>2 >>> bin(b) '0b1111'

Java lang package provides Integer class which has methods to convert an integer to String and vice versa. You can convert a String to an integer using the parseInt() method and Integer to String using the toString() method.ExampleLive Demopublic class Sample {    public static void main(String args[]){       String str = "1212";       int num = Integer.parseInt(str);       System.out.println(num);       String st = Integer.toString(num);       System.out.println();    } }Output1212

Java lang package provides a Double class which has methods to convert Double to String and vice versa. You can convert a String to a double using the parseDouble() method and double to String using the toString() methodExampleLive Demopublic class StringDouble {    public static void main(String args[]){       Double data1 = 2.2;       String str = Double.toString(data1);       System.out.println(str);       Double data2 = Double.parseDouble(str);       System.out.println(data2);    } }Output2.2 2.2

Java String class provides several variants of valueOf() method. These accept various data types and convert them into String.ExampleLive Demopublic class Sample {    public static void main(String args[]){       int i = 200;       float f = 12.0f;       char c = 's';       char[] ch = {'h', 'e', 'l', 'l', 'o'};       String data = String.valueOf(i);       System.out.println(String.valueOf(i));       System.out.println(String.valueOf(f));       System.out.println(String.valueOf(c));       System.out.println(String.valueOf(ch));    } }Output200 12.0 s hello

The toString() method of the String class returns itself a string.ExampleLive Demoimport java.io.*; public class Test {    public static void main(String args[]) {       String Str = new String("Welcome to Tutorialspoint.com");       System.out.print("Return Value :");       System.out.println(Str.toString());    } }OutputReturn Value :Welcome to Tutorialspoint.comThe value of method variants of the String class accepts different variables such as integer, float, boolean etc.. and converts them into String.ExampleLive Demopublic class Sample {    public static void main(String args[]){       int i = 200;       float f = 12.0f;       ...

You can change the cases using the toUpperCase() and toLowerCase() methods of the String class.ExampleLive Demopublic class Sample {    public static void main(String args[]){       String str = "Hello how are you";       String strUpper = str.toUpperCase();       System.out.println("Lower to upper : "+strUpper);       String strLower = str.toLowerCase();       System.out.println("Upper to lower : "+strLower);    } }OutputLower to upper : HELLO HOW ARE YOU Upper to lower : hello how are you

In this program, we will convert a string to both lowercase and uppercase using toLowerCase() and toUpperCase() methods of Java. The toUpperCase() method converts all of the characters in this String to upper case using the rules of the default locale. The toLowerCase() method converts all of the characters in this String to lowercase using the rules of the default locale. Problem Statement Write a Java program that converts strings to lowercase and uppercase using the toLowerCase() and toUpperCase() methods − Input SELF LEARNING CENTER TUTORIALS POINT This is TutorialsPoint www.tutorialspoint.com Output string value = self learning centrestring value = ...
