Varargs and ambiguity

• Unexpected errors may occur when overloading methods that use variable-length arguments.

• These errors often involve ambiguity, where a method call may be ambiguous due to overloading.

• The following program illustrates an example of an ambiguous call to an overloaded varargs method.

• The program shows the correct overload of the vaTest() method, but will not compile due to the ambiguous vaTest() call;.

• The vaTest() call; can be interpreted as vaTest(int...) or vaTest(boolean...), resulting in ambiguity.

static void vaTest(int... v) { // ...
static void vaTest(int n, int... v) { // ...

• The vaTest(1) call can be interpreted as vaTest(int...) or vaTest(int, int...), making it ambiguous.

• In cases of ambiguity, you may need to use different method names or review the code to find a clearer solution.
