Augmented operator is shortcut operator which is used to make easy coding.

When we want to save opration in the same variable like
int x=10;
int y=2;
x+=y;
System.out.println(x);

Output:
12

here , we have used x and y variables for oprations and then rexpress result in terms of one of those variable.

here is some augmented operators:

+= | a += 1 | a = a + 1
-= | a -= 1 | a = a -1
*= | a *= 1 | a = a * 1
/= | a /= 1 | a = a /1
%= | a %= 1 | a = a %1

It is used to make program easy and short.

For example:-
instead of writing :
x =x + 5;

we can write:
x+=5;

Let me know if you have any doubt.
