Java Tutorial: Variable Arguments (VarArgs) in Java A function with Vararg can be created in Java using the following syntax: /* public static void foo(int … arr) { // arr is available here as int[] arr } */ foo can be called with zero or more arguments like this: foo(7) foo(7,8,9) foo(1,2,7,8,9) varargs in java enables a method to accept variable number of arguments. We use three dots (…) also known as ellipsis in the method signature to make it accept variable arguments. For example; public static int sum(int i, intjs ) { //do something } In Java, such types include primitives, raw types, and non-generic types. In contrast, non-reifiable types are types whose information is erased and becomes inaccessible at runtime.

Varargs (variable arguments) is a feature introduced in Java 1.5. It allows a method take an arbitrary number of values as arguments. Normally in a method that takes varargs, we perform the same action on each parameter using a forEach loop, such as in the case of printf, which takes a variable number of arguments and prints them. But since we're wanting to assign member variables, we can't handle these varargs in a forEach loop.
