Whats the main need of Environment variable?
Date : March 29 2020, 07:55 AM
With these it helps Environment variables are set to allow access to command line tools and to enable other tools to interact with SDKs more easily. For example, with Java on Windows, if the environment variable is not set on the PATH, running javac is much more cumbersome because you need to type in the full path to the command each time: C:> \jdk<version>\bin\javac MyClass.java

Whats the correct format of Java String REGEX to identify DOI
Tag : java , By : mtnmuncher
Date : March 29 2020, 07:55 AM
seems to work fine In Java, a regex is written as a String. In other languages, the regex is quoted using /.../, with options like i given after the ending /. So, what is written as /XXX/i will in Java be done like this: // Using flags parameter
Pattern p = Pattern.compile("XXX", Pattern.CASE_INSENSITIVE);
// Using embedded flags
Pattern p = Pattern.compile("(?i)XXX");
/^10.\d{4,9}/[-._;()/:A-Z0-9]+$/i
/^10.1002/[^\s]+$/i
/^10.\d{4}/\d+-\d+X?(\d+)\d+<[\d\w]+:[\d\w]*>\d+.\d+.\w+;\d$/i
/^10.1021/\w\w\d++$/i
/^10.1207/[\w\d]+\&\d+_\d+$/i
String regex = "10.\\d{4,9}/[-._;()/:A-Z0-9]+" +
"|10.1002/[^\\s]+" +
"|10.\\d{4}/\\d+-\\d+X?(\\d+)\\d+<[\\d\\w]+:[\\d\\w]*>\\d+.\\d+.\\w+;\\d" +
"|10.1021/\\w\\w\\d++" +
"|10.1207/[\\w\\d]+\\&\\d+_\\d+";
Pattern p = Pattern.compile(regex, Pattern.CASE_INSENSITIVE);
String input = "http://journals.ametsoc.org/doi/full/10.1175/JPO3002.1";
Matcher m = p.matcher(input);
while (m.find()) {
System.out.println("Start index: " + m.start() +
" End index: " + m.end() +
" " + m.group());
}
Start index: 37 End index: 54 10.1175/JPO3002.1

Whats the correct format for django dateTime in models?
Date : March 29 2020, 07:55 AM
I wish this helpful for you To answer your question, the format for DateTimeField's in Django is defined in the default settings, as documented here: https://docs.djangoproject.com/en/2.2/ref/settings/#datetime-input-formatsAt this point in time it defaults to the following, though obviously may differ depending on the version of Django you're using: [
'%Y-%m-%d %H:%M:%S', # '2006-10-25 14:30:59'
'%Y-%m-%d %H:%M:%S.%f', # '2006-10-25 14:30:59.000200'
'%Y-%m-%d %H:%M', # '2006-10-25 14:30'
'%Y-%m-%d', # '2006-10-25'
'%m/%d/%Y %H:%M:%S', # '10/25/2006 14:30:59'
'%m/%d/%Y %H:%M:%S.%f', # '10/25/2006 14:30:59.000200'
'%m/%d/%Y %H:%M', # '10/25/2006 14:30'
'%m/%d/%Y', # '10/25/2006'
'%m/%d/%y %H:%M:%S', # '10/25/06 14:30:59'
'%m/%d/%y %H:%M:%S.%f', # '10/25/06 14:30:59.000200'
'%m/%d/%y %H:%M', # '10/25/06 14:30'
'%m/%d/%y', # '10/25/06'
]
myfield = models.DateTimeField(null=True, blank=True, default=None)
created_at = models.DateTimeField(auto_now_add=True)
updated_at = models.DateTimeField(auto_now=True)
