Subject RE: Problem in Coding, to get the DOC ID from HITS
Date Fri, 22 Feb 2008 21:34:34 GMT
Of course, these are programming errors nothing really related to
Lucene.

Hits hits;
Int hitCount = hits.length

This does not make sense. You have just declared hits. It must be
created before using it.

The second error should disapper if you add throws declaration or
try/catch block.

By the way, avoid asking such questions in this forum because the
questions are not related to Lucene!!

import org.apache.lucene.search.Hit;

public class comm{
	public static void main(String[] args)
	{
		System.out.println("hi");
	
	
Hits hits;
int hitCount = hits.length();
for (int i=0;i<hitCount;i++) {
   int docId = hits.id(i) ;
  
} 
}
}

and the error i am getting is

C:\Documents and Settings\Sumit\Desktop>javac db/comm.java
db/comm.java:15: variable hits might not have been initialized
int hitCount = hits.length();
               ^
