Using different arithmatic assignment operators in java program

class assignops
{
public static void main (String arg[])
{
int a=10,b=25,c=5,d=18,e=49;
a+=10;
b-=10;
c*=10;
d/=2;
e%=7;
System.out.println ("\n\t a = "+a);

System.out.println ("\n\t b = "+b);
System.out.println ("\n\t c = "+c);

System.out.println ("\n\t d = "+d);
System.out.println ("\n\t e = "+e);
}
}

Note:

          After execution you will observe following five changes

1. Value of 'a' is increased by 10
2. Value of 'b' is decreased by 10
3. Value of 'c' is 50 (due to multiplying by 10)
4. Value of 'd' is 9 (because we are dividing 'c' by 2)
5. Value of 'e' is 0 (because 7 divides 49 properly)
