Increment and Decrement \\\\\\ Operators in Java

int y = 10;

y--; // y ki value ab 9 ho jayegi

 Java me Increment ya decrement operators ka use numeric values ko teji se bdhane ya ghatane me kaam aata hai , this is only a shortcuts of addition && subtraction

here is an example of this - - - - - - - 

• Increment Operator (++): Increment operator ++ ek variable ki value ko ek unit (1) badhata hai. Is operator ko variable ke peechhe lagate hain. For example:

int x = 5;

x++; // x ki value ab 6 ho jayegi

•  Decrement Operator (--): Decrement operator -- ek variable ki value ko ek unit (1) kam karta hai. Is operator ko variable ke peechhe lagate hain. For example:

int y = 10;

y--; // y ki value ab 9 ho jayegi

Post Increment--
x++;

• ise ham post increment kehte hai
• ++xx ise ham pre increment kehte hai 
• agar ham ++ phle lga rhe hai to use pre increment kehte hai 
• agar ham aage laga rhe ++ ya -- to ise ham post increment kehte hai. 
• ye saaare same work krenge you can post increment || pre increment ....... Lekin pre increment me pre increment ue krenge to wo increment phle krega phir print krega

Here is an example of post increment 

you can see yaha increment to hua hai but its not showing on console 

1. post increment me purani value phle deta hai aur increment uske bad krta hai .. .. .. 

• Pre increment 

Pre increment me ---

pre increment me increment phle hoga , keh skte hai increment hoke print hoga .

1. yahan aap dekh skte hain phle increment kiya gya hai phir print hua hai 1 
2. agr && operator use ho rha aur 2 conditions hai  if(x++ > 10 && ++y > 20 ){  kuch is trh ke to dono condition agr true hoga tabhi x and y dono increment honge , aur print hoga increment hokar , 
3. lekin agar || (((OR)))) operator use kr rhe  if(x++ > 10 || ++y > 20 ){ isme dono me se koi v true hoga to increment dono hoga isliye iska answer 11 21 hoga 

Relational Operators ki value boolean hoti hai 

this is Logical Operators

1. && operators me jab dono statement true hai tabhi final result true hoga agr ek bhi false hoti hai to final result false hoga.
2.  || or operators me agr ek v statement true hogi to final result true hi hoga . aur return krega true . . .
3.  ! logical not ka kaam kisi v statement ko false bnana .

----------------------------------bitwise operators----------------------

Single & bitwise me aata hai aur && double && logical me aata hai
