Explanation

Varargs allow a method to accept a
variable number of arguments.

Code:

void display(int... numbers) {
    for(int n : numbers) {
        System.out.println(n);
    }
}

Explanation

Varargs are treated as arrays inside the method.

Code:

void sum(int... values) {
    System.out.println(values.length);
}

Explanation

Varargs parameter must be the last
parameter in the method.

Code:

void example(String name, int... marks) { }

Explanation

You can call varargs method with zero or
more arguments.

Code:

display();
display(1, 2, 3);

Explanation

Only one varargs parameter is allowed in a
method.

Code:

// void test(int... a, int... b) {} // Not allowed
