Return Type of Java Generic Methods
user975343 :
I wonder why generic methods which return nothing void are (or can be) declared this way:
public static <E> void printArray( E[] inputArray ) {
// Display array elements
for ( E element : inputArray ){
System.out.printf( "%s ", element );
}
System.out.println();
}
It seems like <E> is the type of the returned object, but the method returns nothing in fact. So what is the real meaning of <E> in this case specifically and in generic methods generally?
Jops :
This question suits one of my old notes. I hope this illustration helps:
