null problem

[Nick Lebian]

Hi!
How can I find out, if the return value of a String method is null?
....
List list=new HashList();
for (int i=1; !this.getParameter("gap"+1).equals(null); i++)
{
System.out.println("While");
String gap=getGaps(this.getParameter("gap"+i));
String[] pointer=gap.split(";");
list.add(pointer);
}
...
But in this case, the for loop doesn't stop.

Try this:
for (int i=1; this.getParameter("gap"+1) != null; i++)

If the return value is the string "null", then it should be checked like this...
for (int i=1; !this.getParameter("gap"+1).equals("null"); i++)
