creating a generic static method in java
I wanted to create a static method which prints the contents of an array.I
wrote one for String[] as below
public static void print(String[] a){
for(String x : a){
System.out.print(x+", ");
}
System.out.println();
}
I thought I could create a method which takes in a generic type ,and
modified the code as below
public class ArrayPrinting<E> {
public static void printArray(E[] a){
for(E x : a){
System.out.print(x+", ");
}
System.out.println();
}
public static void main(String[] args) {
String[] a = {"A","B","C","D","E"};
}
}
But,this gives a compiler error
'Cannot make a static reference to the non-static type E'
So,how do I create such a method?or is it impossible ? Since this is a
static method, I wonder how I can invoke the method without creating an
instance. A call like
ArrayPrinting<E>.printArray(a) doesn't look right ..
Can someone help?
