Can anyone help me with this question output am getting confused

Question

Int x =10;
System.out.println (x++);
System.out.println (x++);
System.out.println (x--);
System.out.println (--x)

Answer 1

1) : Post increment x++ : first value is returned or used there after then it increments.. so first it will print 10 then it increments x+=1 => x=11

2) : Again same happens so prints 11 and then x incremented so x=12

3) : Post decrement x-- works same first it uses value then decrements so prints 12 then decrements, x=x-1=>x=11

4): Pre -decrement operator --x : here first it decrements value then uses its value so x=x-1=>x=10, then it prints value so output is 10 for this.
(Pre-increments works same instead increments instead of decrement)

So output is
10
11
12
10

Answer 2

First you should learn basics of increment and decrements then u can easily solve these questions.

Always in the expression pre increment or pre decrement will be evaluate the. Post increment or decrement

Here in first line x++ this is post increment so i told pre increment will be solve so here first x value will be printed 10 then it will increase. After printing 10 now x++ will increase by one so current value of x is 11
Then again same things so
11 will be print then value increasing by 1 so current value will be 12
Again value will be print and in third statement here is x-- so first value will be print 12 then it will decrease by 1
Then in fourth Statement there is --x which ia pre decrement so first value will be decrease so now this time 10 will be print

so final output will be
10
11
12
10

Can you please tag Java instead of 'girlscode'? Java is the language that is relevant to your snippet.

It's important to use proper tags ...
