So I'm basically finished with a program, and at the end of it I'm printing Strings from an array to a file. The array may contain null values, so I'm checking for null before I print, but I keep ending up with 1 null at the very end of the file...
Here's the code I'm using to check for null
for(int i=0;i<array2.length;i++)
{
if(array2[i] != null)
out.println(array2[i]);
}
I know that the array contains multiple instances of null, but only 1 is being printed. I tried using the debugger and when array2[i] == null, it still entered the conditional statement...
So I added a println statement to help me see what's going on. It now looks like this:
for(int i=0;i<array2.length;i++)
{
if(array2[i] != null)
{
System.out.println("Adding " + array2[i]);
out.println(array2[i]);
}
Just after printing all the String values to the console, it prints "Adding null" so I know it's happening here in this if statement. Why is this happening???
