K & B P.No: 456 states that:

you must give valid new File object with the new name you want. If the new file object is null, NullPointerException will be thrown


Consider the code:


Line 01 must throw NPE but it doesn't.....a new directory with name "name" is created in the current directory and the programs compiles and runs successfully....
What should i conclude?


Waiting for enlightenment....

How do you tell, that the program doesn't give Exception, you should check it. Try the below code..


|BSc in Electronic Eng| |SCJP 6.0 91%| |SCWCD 5 92%|
