++ Confusion in java

Question

++a , a++ what is difference

Answer 1

Devashish kumar ,

here a short description:

=> *pre-increment* operator: ++x
is used to increment the value of variable `x` **before** using it in an expression.

=> *post-increment* operator: x++
is used to increment the value of variable `x` **after** executing the expression.

Answer 2

++a : pre-increment
a++ : post-increment

Answer 3

EXAMPLE - pre-increment
x = 5;
y = ++x; (increment x to 6, then assign 6 to y)

EXAMPLE - post-increment
a = 5;
b = a++; (assign 5 to b, then increment a to 6)

Both cases have the side-effect of incrementing and saving the variable.
Just a question whether you access the value of the variable before or after the increment happens.

Answer 4

Lol

Answer 5

int a=0, b=10;

a = b++; // first a=10, then b=11
System.out.println("a="+a+", b="+ b);

a = ++b; // first b=12, then a=12
System.out.println("a="+a+", b="+ b);
