Using regex to match any character except =

Question

I am trying to write a String validation to match any character (regular, digit and special) except =.

Here is what I have written -

    String patt         


        

Answer 1

If the only prohibited character is the equals sign, something like [^=]* should work.

[^...] is a negated character class; it matches a single character which is any character except one from the list between the square brackets. * repeats the expression zero or more times.
