private static int getStrength(String pw) {
int strength = 0;
if(pw.length() >= 8){
strength++;
[Code] .....
This function doesn't seem to work for me. I believe the issue lies in the special character matching. It seems like it always returns true and adds to the strength. But I only want it to add to strength if at least one the following are in the password: *, -, _, ^, !, %
I have a regular expression that I created and tested on some regex site, [URL] .... It worked on the test site but I can't get it to work in Java.
The code is:
String s = "MyString.ext_CAL3";
assertTrue("Didn't Match", s.matches("_CAL[0-9]+$"));
This test always fails. I cannot figure out what is wrong with it. In fact, I can't get any match no matter what regex I use.
URL....my file name can contain special characters but when I passing this file name as a parameter in URL using REST.I am getting exception.
View Replies View Relatedso my task is to write a code which would ask user to input the year as integer and first three letters of the month with first being an upper case letter. Than the program would determine the number of days for given year and month.
Currently I have a brain crash on how to check, if the user has provided the month with first character being upper Case. If not, than the program would automatically correct the character. Problem starts at line 17.
import java.util.Scanner;
public class DaysOfMonth4_17 {

//Initiate scanner
Scanner input = new Scanner (System.in);
//Ask for year input and use is as INT
System.out.println("Enter the year");

What I am trying is find the XOR value between charcters of a String here is my code
public static void main(String[] args) {
System.out.println(grayCode("100"));

StringBuilder temp=new StringBuilder();
temp.append(input.charAt(0));

char previous=input.charAt(j-1);
char current=input.charAt(j);
char xorVal=(char)(previous^current);
temp.append(xorVal);
}
return temp.toString();
}
but I am not getting actual XOR value of two charcters that I am trying to get.

Several kinds of celebration dates are displayed.
Say Marriage, a new baby is born and so on. Such special dates are not fixed to be once or twice.
Such that a person can have a marriage and a new born baby celebration or both. One of my thoughts was to used several (up to 3). JLabels and JDateChoosers, but it is quite limiting.
How should I design such a component so that it can accommodate several major events of life.
Facing problem with java.net.InetAddress class while validating special form of IPv6 address.
Please check the following piece of code.

It is throwing ClassCastException.
I need to create a regexp, that will do the following:
a,a,a,a,c - matches
c,a,a,a,a - matches
a,a,a,a,a - doesn't match
I will be using it in Java. In the place of 'a', can be 'b' - they are equal. Also, in the place there can be any other character. This is what i have came up with:
^(?=^(a|b)).*((a|b),){4}(?!(a|b))|(?!(a|b)).*(((a| b),*){4})$
It fails because it matches the 5 a's. I'm quite new to regexp, so I'm not aware of all the possibilities. It matches the 5 a's, because the first if fails, but the second does not. Maybe there is a simpler way to accomplish this? (Also why are the .* necessary in the middle?)
I'm trying to use regex to find a word containing the substring "cat." I'm not sure why this isn't working?
String match = "^ cat$";
I would like to test whether the first word in a line is is a valid var name (e.g sequence of letters, digits and "_", it may not start with a digit, if "_" is the first char it must be followed by a letter). I tried this simple code:
String namePattern = "_[a-zA-Z0-9]+";
String text = "__c";
Pattern pattern = Pattern.compile(namePattern);
Matcher matcher = pattern.matcher(text);
"__c" is an illegal var name.
But it returns the string "_c", where it is supposed to return an empty matcher.
where am I wrong here?

I am in need of regex for alphanumeric (uppercase only) values which will verify string of length 5below
ABCCD - False
AB12C - True
ABC12 - True
12ABC - True

If it contain any lowercase then it should result in false as well.

I am trying to write a regular expression for a text which has both String and number... like abc1234, xyz987, gh1052 etc. And the string usually contains 2 or 3 characters.
What I need is two Strings one containing the text (abc, xyz, gh etc) and other containing number (1234, 987, 1052, etc.). Have written the code below. but doesn't seem to work.
String query = "abc1052"; //Or query = "zyx900";
String regexp = "(.{3})(d*)|(.{2}(d*))";
Pattern pattern = Pattern.compile(regexp);
Matcher match = pattern.matcher(query);
if(match.find()){

Also tried with regexp = "(.s*)(.d*)" in no avail.
Finally achieved with regexp = "(D*)(d*)";
I am using the following regex - [a-zA-Z0-9]{9,18} which means I can use alphabets and numbers with minimum length as 9 and maximum length as 18.It should not take special characters.
It takes values like ADV0098890 etc. but it is also taking ADV0098890[] which is wrong.
How can I prevent that ?
I have a table which contains list of regular expression and its corresponding value.I have to fetch those value and put it HASHMAP where regex as key.I have to compare the each key with the given string(input) and If matches I have to get the corresponding Value for the regex.
View Replies View RelatedWith the code below, I am trying to replace all regex matches for visa cards within a given text file.
My first test was with a text "new3.txt" exclusively containing the visa test card 4111111111111111. My objective was to replace the card with "xxxx-xxxx-xxxx-xxxx". This was successful.
However, when modifying the text file to include other characters and text before and after (ex: " qwerty 4111111111111111 adsf zxcv"), it gives mixed results. Although it successfully validates the match, it replaces the whole text in the file, rather than replacing solely the match.
When trying this search and replace with words (rather than a regex match), it does not have this behavior. What am I missing?
