Java NullPointerException. Why?
- by user292844
I am new to Java. I just read that class variables in Java have default value. I tried the following program. I was expecting to get the output as 0, which is the default value on an integer, but I get the NullPointerException. What am I missing?
class Test{
static Integer iVar;
public static void main(String...args) {
System.out.println(iVar.intValue());
}
}
