Switch

The switch statement can be used to handle several alternatives if they are based on the same constant value.

switch (expression) {
    case constant1:
        command;
        break; // will prevent that the other cases or also executed
    case constant2:
        command;
        break;
        ...
    default:
}

// Example:

switch (cat.getLevel()) {
    case 0:
        return true;
    case 1:
        if (cat.getLevel() == 1) {
            if (cat.getName().equalsIgnoreCase(req.getCategory())) {
                return true;
            }
        }
    case 2:
        if (cat.getName().equalsIgnoreCase(req.getSubCategory())) {
            return true;
        }
}

// you can also use the same logic for different constants

    public static void main(String[] args) {
        for (int i = 0; i < 6; i++) {
            switch (i) {
            case 1:
            case 5:
                System.out.println("Hello");
                break;
            default:
                System.out.println("Default");
                break;
            }
        }
    }
