Why my this code shows 'NO OUTPUT' ?

Question

import java.util.ArrayList;

public class MyClass {
public static void main(String[ ] args) { int i;
ArrayList<Integer> colors = new ArrayList<Integer >(10);
for(i=0;i<colors.size();i++)
{
colors.add(i);
}
System.out.println(colors.get(1));
}
}

Answer 1

colors.size() returns 0 at first. It doesn't matter how much (10 here) you specify in declaration.

Change the loop condition to "i < 10" for your code to work.
