Java machines work on the fourth week

1. programming, the value of the input variable x, if it is 1, output x = 1, if it is 5, the output x = 5, if it is 10, x = 10 outputs, in addition to the above several values are output x = none. (Knowledge: if conditional statement)

Package BaO;

2. To achieve the first question with a switch structure

        Scanner SC = new new Scanner (the System.in);
         int I = input.nextInt ();
         Switch (I) {
             Case . 1 :
                System.out.println("x="+i);
                break;
            case 5:
                System.out.println("x="+i);
                break;
            case 10:
                System.out.println("x="+i);
                break;
            default:
                System.out.println("x=none");
                break;
        }
 
    }
}

Determining whether a number is 3. 5 and 6 can be simultaneously divisible (5 and 6 can be divisible print), or can only be divisible by 5 (5 be divisible print), or can only be divisible by 6, (6 can print divisible ), can not be divisible by 5 or 6, (printing can not be divisible by 5 or 6)

4. Enter a score of 0 to 100, if not between 0 to 100, the print score is invalid, printing A (90-100), B (80-89) according to grade scores, C, D, E (knowledge: Condition statement if elseif)

5. Enter three integers x, y, z, please small to large number of these three outputs (knowledge: conditional statements)

Package BaO;

                    System.out.println ( "press from order of small to large: "C + +", "+ A +", "+ B);
