Difference between Arrays and 3 dots (Varargs) in java

Question

I cannot figure out that what are the differences between ... in java and arrays also array list, especially array list.

Both we can use as unlimited bu

Answer 1

The three dots can only be used in a method argument, and are called 'varargs'. It means you can pass in an array of parameters without explicitly creating the array.

private void method(String[] args) {} is called like method(new String[]{"first", "second"});

private void method(String... args) {} is called like method("first", "second");
