Var-arg doubt

[Ravi Yadav]

Hi,

I was experimenting with this piece of code:
Why does this code throw a compiler error:
.....
class Test{
void fun1(double... s){
System.out.println("inside A");
}
void fun1(float...a){
System.out.println("inside S");
}

public static void main(String arg[]){

new Test().fun1(5);
}
}
.....
Test.java:11: reference to fun1 is ambiguous, both method fun1(double...) in Tes
t and method fun1(float...) in Test match
new Test().fun1(5);


However this doesnt:

class Test{
void fun1(double s){
System.out.println("inside A");
}
void fun1(float a){
System.out.println("inside S");
}

public static void main(String arg[]){

new Test().fun1(5);
}
}

Thanks,
Ravi

The compiler cannot find the most specific method. Remember, it's trying to compare float[] and double[] and they are not comparable.
