Question

Timestamp[] lastreply = new Timestamp[100];
replyr = lastreplyr[i].getTime();
System.out.println("Replyr: "+replyr);
lastreply[count].setTime(replyr);
System.out.println("lastreply: "+lastreply[count]);

Console:

Replyr: 1321116689000
java.lang.NullPointerException
    at website.web.InboxReader.getLastReply(InboxReader.java:937)
    at website.web.InboxReader.main(InboxReader.java:55)

Why is lastreply getting null? In the code, count begins from 0.

Thanks.

Answer 1

This is the problem:

lastreply[count].setTime(replyr);

lastreply[count] is null, because Timestamp is an object.
When you instantiate an array of objects then all the values are null. You need to insert references to objects first before start using them.
