[b]if we don't throw the exception which was caught then that thread will not be closed[/b] So we always have to throw the exception and bring the exception to start point ...there u catch and do the needful and close it It is not right practice to catch Exception (without throwing) [/quote] Confused.... more simple explanation please....

[/quote] suppose { T1 T2 } This is T2 This a thread runs on it own say for example.. and what ever that happens in the try is being used in another thread (T1) now there is an exception .. try{ }catch(Exception e){ System.out.println() ; } now if there is an error and in catch if u don't throw to parent thread ... Nothing will happen ...but threads will be alive.. if u throw the exception then it reaches to main { T1 T2 } then u can close both as well inform the party why u couldn't not process. mostly happens in multi threaded env.

vijayjust4u Posted September 12, 2013 Report Posted September 12, 2013 Jailer mama, good attempt. But I am thinking of this... not sure if it makes sense... try catch is too much of boiler plate code.... I mean, catch block ni carefull gaa cheyyali..... But, if you can write the method logic, by design by contract principle, you can avoid lot of exceptions... Example, null pointer exception ... before performing an operation on the variable/object... check if the value/object is null.... etc... So disadvantage is...too much of code and maintaining the same I could be wrong, just my version....
