Guys i can't understand the difference between prefix and postfix

Answer 1

It is pretty simple.

Pre means before
Post means after

In your example
x = 14;
system.out.print (x++);

14 is printed because x is incremented 'after' (postfix) the print statement is executed.

Answer 2

if you are talking about the Increment and Decrement (++ or --)

Answer 3

it is very easy....
prefix (++x) adds 1 to the valuee of x and then assigns to the X....
postfix (x++) uses value of x and then add 1 to the value of X....

here,,
x=3;
y=x;
x++ will result in x=4... it will just change the value of itself accoriing to the condition above while in case of prefix..

x will be 4 and y will also be 4.... because here x has value for and according o the condition it will use its value and assing to y..

very simple...

Answer 4

But why in the example in the app x=14 and system.out.print(x++) output 14 and not 15 ? Can anyone explain to me , please ?
