problems in recognising & in a string

[pooja]

how can one recognise & in java string when taken as command line
argument,as many special characters like |,>,<, & and * are never
accepted in the string and no exception ever handles them ,so I have
already made an exception in my code to handle these 5 characters ie
by using switch case,anyways the control does not recognises & and
still crashes,means does not gets into the catch statement while in
other 4 cases >,< ,|,* it does, how can this problem solved?

There is a bug in your code. You did not include any code.
'&' is a character like any other. There is no special cases
involving that character.
