Enhanced For Loop

[terahawks]

Hi,

To begin with, am pretty new to this enhanced for loop concept. Tried first few hands on it and found it pretty cool. I have a doubt regarding the enhanced for loop. The doubt is that what if we am using array of class type the in that case can i use enhanced for loop? if yes then how? or is enhanced for loop restricted to primitive type?

Thank you

Seeing as you declare the type to be "extracted" on the left hand side of the ":", I would have to assume, from that alone, that it will work for any type.

i have a piece of code that show this

public class TestClass {

	private int i;

	public int getI() {
		return i;
	}

	public TestClass(int i) {
		this.i = i;
	}

	public static void main(String[] args) {
		TestClass[] t = new TestClass[2];

		t[0] = new TestClass(1);
		t[1] = new TestClass(2);

		for (TestClass c : t) {
			System.out.println(c.getI());
		}
	}

}

the problem here is if the TestClass is declared with more elements and these are not filled then the loop will cause a NullPointerException. but the purpose of the code above is to show a loop through a collection that contains not primitives but objects. and in real life there are better collections then arrays to use.
