Need Java Code for following questions:

19002. Write a regular expression that selects lines containing any of the following words: linux windows solaris macos. For this exercise you must surround your solution with double quotes.

19003. Write a regular expression that selects lines containing a social security number (either in pure nine digit form, ddddddddd, or broken up with hyphens in the standard way: ddd-dd-dddd) For this exercise you must surround your solution with double quotes.

19004. Write a regular expression that selects lines containing a phone number. Assume a U.S./Canadian number with a 3-digit area code, a 3-digit exchange and another 4 digits. An additional extension is also possible. Assume that the phone number will have dashes or periods in the "usual" way: 718-951-5000 or 718.951.5000. Dashes and periods cannot be mixed. Also, the area code may be surrounded by parentheses: (718)-951-5000. Extensions, if present, will start with an X or an x, preceded by a space or nothing and followed by at least one and no more than four digits. Oh, and one other thing: area codes do NOT start with 0 or 1, do they? What a mess! (But somebody has to do it-- and that's you!) For this exercise you must surround your solution with double quotes.
