Class VS Object

  Classes in java Classes are used to store our code  Classes in java can be created using class keyword Class is like a blueprint where we can write all of our requirements   Ex:-  fileName- Demo.java class Hello{  public void print(){ System.out.print("It is in print() in Hello class"); } } Objects in java Objects are used to store the attributes of a class It is like instance of a class It stores all attributes of a class If we want to access the features of a class we use objects Ex:- fileName- Demo.java       <Same file> class Demo { public static void main (String []args){ Hello h=new Hello(); // 'Hello h 'is a reference of class Hello class // new Hello() is a instance of a class Hello // By combining the two we get object it means it stores the all attributes/ features of class Hello  // .(dot) is used to access the specific features of the class  h.print(); } }

DATA TYPES

Data Types are used to specify the type of data that is used to store. int                  used to store integer value. char                used to store characters and we use single quotations to specify character . float                used to store the decimal values up to 6 decimals. double            used to store the decimal values up to 8 decimals. byte                used to store the byte code values. short              used to store the short Integer values. long                used to store the long Integer values. Examples :- int  106 0 -635 char 'q' 'L' '+' '$' float 61.562f -96.386245f 5462.15f double 0.3215 45.21 78.96325874 byte 127 -128 65 short 32...
