In Java, “default” is a keyword that serves as a modifier for access control and as a label for switch statements. Its meaning depends on the context in which it is used.

Access Control

When used as an access modifier, “default” (also known as package-private) allows members to be accessible within the same package but not outside it.

Switch Statements

In switch statements, the “default” label is used as a fallback when none of the other case labels match the switch expression’s value.

    // Access modifier example

    }
    
    // Switch statement example
    switch (day) {
        case 1:
            // Code for day 1
            break;
        case 2:
            // Code for day 2
            break;
        default:
            // Code for all other days
            break;
    }
