How to match strng such as ""?

java String.matches() can match string "<" (only one character) using regex "<", "\074", "[\074]", etc, but if there are other characters in the string, it cannot be matched.
If grep, if using -E switch, "<" can be matched.

Try doing

Pattern p = Pattern.compile("");

Then use the find() method on the Matcher object to check for a match.

unlike regular expression in shell script, u need to escape twice in order to insert a special character:



example:

"\\@" - in java

\@ - in shell script

The regex you prefer is /(H|h)ello.*(.*)/ (H|h)ello starts the a risk tournament with hi or hi .*     observed with the aid of any form of any character (     observed with the aid of the left parenthesis .*     observed with the aid of any form of any character )     observed with the aid of the wonderful parenthesis Any string with the development hi ....( ...) ... will try real with the regex given
