Content
0.24 -> hi everyone in this video i will be
showing you how to solve the error
4.64 -> unreported exception file not found exception must
be caught or declared to be thrown so i am getting
10.8 -> this error when i try to read the content present
in this particular text file and display it
15.44 -> so i'll be showing you how to solve this
exception all right am having here a really
18.88 -> really simple code to read the contents of
the file and display it if you want you can
22.16 -> just pause the video and type it out and in my
case i'm just directly specifying the file name
27.36 -> because my dot java file and my dot txt file are
present in the same folder alright so actually
33.44 -> there isn't any error in this code but we are
getting an exception so the simplest way to solve
38.24 -> this is enclosing our entire code within a try
catch block all right so just come here to the top
45.92 -> and here you need to specify try open curly
bracket and just enclose the code alright
53.04 -> so once you're done enclosing it you'll be
having the catch block so it's going to be
57.2 -> catch and open circular bracket and curly bracket
so here you need to specify exception all right
64.16 -> so it's going to be exception e so you can
basically print the name of the exception
68.64 -> you can do this way like system dot out dot
print the exception or you can just have
78.24 -> some print statement like you can just
have error something like that you can
82.72 -> do whatever you want i will do with this
so this is now fine so i am now saving it
90.4 -> and recompiling it again
95.68 -> so this time you can see when i compile i'm not
getting any error or exception which is because
99.76 -> of the try catch block that we have added over
here that's the main reason and if i just now
105.6 -> run this as well i'll be getting i am java this
text basically is present inside my file over
112.48 -> here yeah so here you can see i'm having this
text so which means that this program is working
118.48 -> 100 percent fine and we have now solved this issue
this file not found exception and i hope you have
124.88 -> found this video useful i've also done many other
