?int three = 0 ;
??????? three=one+two;
??????? System.out.println("three = one + two ==> "+three);
??????? three+=one;
??????? System.out.println("three += one ==> "+three);
??????? three-=one;
??????? System.out.println("three -= one ==> "+three);
??????? three*=one;
??????? System.out.println("three *= one ==> "+three);
??????? three/=one;
??????? System.out.println("three /= one ==> "+three);
??????? three%=one;
??????? System.out.println("three %= one ==> "+three);
