This is how I encountered the problem. I am giving an example:
package check; public class Check { int a,b; Check (int i,int j) { a = i; b = j;
Think that it's not warning you and you write a piece of code like:
V v = new V();
Then, what would you expect your compiler to behave? I mean, there is no no-arg consructor defined. You need to explicity add it.
Check() { }
