In Java, when a method returns an array, how do you find the size or length of the array returned?

Question

The actual code is:

String[] pieces=whole.split("^");

I need to iterate through the array, but there doesn't seem to be a method similar to ArrayList's size( ) that will give me the size/length.

**THANKS SO MUCH; I knew I had done this a million times but I was drawing a blank!

Answer 1

int noOfElements = pieces.length;

use the var noOfElements for looping...

HTH

Answer 2

Like almost everything in Java, arrays are handled by a class behind the scenes. The array class has a public final field named "length" which contains the size of the array.

pieces.length

Answer 3

String pieces[] = whole.split("^");

//use the length attribute to get the number
//of elements in an array
for(int i = 0; i < pieces.length; i++ ) {
System.out.println("piece: " + pieces[i]);
}
