💡 Hint

Common Mistakes

Putting a number instead of the variable inside switch parentheses.

Writing 'switch' or 'case' inside the parentheses.

The switch statement must use the variable day inside the parentheses to decide which case to execute.

💡 Hint

Common Mistakes

Using 5 or 8 instead of 7 for Sunday.

Adding break between case 6 and case 7, which stops fall-through.

To cover both Saturday (6) and Sunday (7), you add case 7 after case 6 without break.

Fix the error by completing the code to handle the default case correctly.

Java

int day = 3;
switch(day) {
    case 1:

        break;
    case 2:
        System.out.println("Tuesday");

}

💡 Hint

Common Mistakes

Forgetting the quotes around the string.

Using mismatched or incomplete quotes.

The default case must print a string literal, so it needs to be in double quotes.

Fill both blanks to complete the switch statement that prints the name of the month for month 1 or 2.

Java

switch(month) {
    case [1]:
        System.out.println("January");
        break;
    case [2]:
        System.out.println("February");
        break;

💡 Hint

Common Mistakes

Using 0 or 3 instead of 1 or 2.

Mixing up the order of months.

Month 1 is January and month 2 is February, so cases must be 1 and 2 respectively.

5fill in blank

hard

Fill all three blanks to create a switch that prints the day name for day 1, 2, or 3.

Java

switch([1]) {
    case [2]:
        System.out.println("Monday");
        break;
    case 2:
        System.out.println("Tuesday");
        break;
    case 3:
        System.out.println([3]);
        break;
    default:
        System.out.println("Invalid day");
}

💡 Hint

Common Mistakes

Using a number instead of the variable in the switch.

Forgetting quotes around the day name string.

The switch must use the variable day. Case 1 prints Monday, and case 3 prints Wednesday as a string literal.
