Initialising A Variable In JAVA

INITIALISING A VARIABLE IN JAVA

Hello Geeks!!!

INITIALISATION IS CARRIED ON CONSTANTS, VARIABLES AND DATA TYPES

OVERVIEW :-
  • CONSTANTS ➡ It Is a Number That Does'nt changes Its Value And Remains Same Throught The Program.
  • VARIABLES ➡ It Is Number Or Variables That Varies Throughout The Program. Its Value Can Be Assigned by Constants.
  • DATA TYPES ➡ It Is A Particular Kind Of Data Item, As Defined By The Values It Can Take.Diffrent Types Of Data Types In JAVA are : 
           Integer - int - int a = 22;
           Float - float - float b = 3.14;
           Double - double - double c = 5.454584654;
           Character - char - char ch =  'a';
           String - String - String str = "JAVA";
There are Many More Data Types But These are The Basic Data Types We Need To Know While We Are New At JAVA.

PROGRAM :-

//Initialising Variables
/*
**1st-We Have To Declare CLASS 
**2nd-We Have To Declare MAIN Function 
**3rd-We Have To Declare And Initialise Variables 
*/

public class InitialisingVariables //Class 
{
    public static void main (String args[]) //MAIN Function
{
     int a = 22;
     float b = 0.1F;
     double c = 5.454584654;
     char ch =  'a';
     String str = "JAVA";
     
   System.out.println(a); //Print Statement
   System.out.println(b); //Print Statement
   System.out.println(c); //Print Statement
   System.out.println(ch); //Print Statement
   System.out.println(str);  //Print Statement

    
     } //Closing of Main Function
 } //Closing of Class

NOTE :-  To RUN Your Code You Can Either Write Yourself  Or Copy The Above Code Into Any JAVA IDE's (Integrated Development Environment) Or Any Online Compiler


























OUTPUT :-


TEST YOURSELF :-

QUES -- WRITE A JAVA PROGRAM TO STORE AND INITIALISE VARIABLE AND PRINT IT

INCREMENT IN JAVA  Hello Geeks!!! OVERVIEW  :- Increment : Increment Is Change In Value Of The Variable. It Is The Addition Of +1 to The Variable. Two Types Of Increment : Pre-Increment                                               Post-Increment  Pre-Increment : It Is The Change Of Value Before The Execution. SYNTAX- ++variable. Post-Increment :  It Is The Change Of Value After The Execution. SYNTAX- variable++ PROGRAM :- // Increment In Java public class Increment { public static void main (String args[ ]) { int a=5,b=10; a=++a; //Pre-Increment b=b++; //Post-Increment System.out.println ("A = "+a); System.out.println ("B = "+b); }  }  OUTPUT  :- TEST YOURSELF :- QUES -- WRITE A JAVA PROGRAM TO STORE AND INCREMENT VARIABLE AND PRINT IT You can...
