Simulation and EmulationEmulation is the process of the replica of the visible behavior in order to match the existing target. The inner state of this mechanism does not need to reflect the internal state of the target precisely. The emulator is used in order to emulate.Simulation, in fact, involves modeling the inner state of the target to which stimulation is done. The end result of a noble simulation is that this mechanism will emulate the target that it is simulating. A simulator does this process.Except for the actual definition, the other points of difference between the Simulator and an Emulator ... Read More
The find() method finds the subsequence in an input sequence that matches the pattern required. This method is available in the Matcher class that is available in the java.util.regex package.A program that demonstrates the method Matcher.find() in Java regular expressions is given as follows:Example Live Demoimport java.util.regex.Matcher; import java.util.regex.Pattern; public class Demo { public static void main(String args[]) { Pattern p = Pattern.compile("Sun"); Matcher m = p.matcher("The Earth revolves around the Sun"); System.out.println("Subsequence: Sun"); System.out.println("Sequence: The Earth revolves around the Sun"); if (m.find()) ...

You need to use LOCATE() along with SUBSTR(). The below syntax will find the word after delimiter. Here, delimiter is colon(:), you can use another i.e. it is up to you. The syntax is as follows −SELECT SUBSTR(yourColumnName, LOCATE(':', yourColumnName)+1, (CHAR_LENGTH(yourColumnName) - LOCATE(':', REVERSE(yourColumnName)) - LOCATE(':', yourColumnName))) AS anyAliasName FROM yourTableName;To understand the above syntax, let us create a table. The query to create a table is as follows −mysql> create table SearchTextBetweenDelimitersDemo -> ( -> ... Read More
To apply modulus (%) operator to floating-point values in an effortless task. Let us see how.We have the following two values −double one = 9.7; double two = 1.2;Let us now apply the modulus operator −one % twoThe following is the complete example that displays the output as well −Example Live Demopublic class Demo { public static void main(String args[]) { double one = 9.7; double two = 1.2; System.out.println( one % two ); } }Output0.09999999999999964

You can use WHERE clause and OR operator to show table with multiple LIKE. The syntax is as follows:show table from yourDatabaseName where tables_in_yourDatabaseName Like ‘%anyTableName%’ or tables_in_yourDatabaseName Like ‘%anyTableName2%’ or tables_in_yourDatabaseName Like ‘%anyTableName3%’ . . . . or tables_in_yourDatabaseName Like ‘%anyTableNameN%’In the above syntax, only the table name in the database is displayed.Here the database ‘test’ and the tables in the same database is considered. The query to show tables with multiple LIKE is as follows -mysql> show tables from test -> where tables_in_test like '%userrole%' -> or tables_in_test like '%view_student%' -> or tables_in_test like '%wholewordmatchdemo%';The following is the ...

The Matcher can be reset using the java.util.regex.Matcher.reset() method. This method returns the reset Matcher.A program that demonstrates the method Matcher.reset() in Java regular expressions is given as follows:Example Live Demoimport java.util.regex.Matcher; import java.util.regex.Pattern; public class MainClass { public static void main(String args[]) { Pattern p = Pattern.compile("(a*b)"); Matcher m = p.matcher("caaabcccab"); System.out.println("The input string is: caaabcccab"); System.out.println("The Regex is: (a*b)"); System.out.println(); while (m.find()) { System.out.println(m.group()); } m.reset(); System.out.println("The ...

In MySQL, now() can be used to insert current date/time. The syntax is as follows −insert into yourTableName values(now());To understand the above concept of inserting current date/time in the table, let us first create a table −mysql> create table CurrentDateTimeDemo −> ( −> YourTime datetime −> ); Query OK, 0 rows affected (0.58 sec)Inserting current date/time using now(). The query is as follows −mysql> insert into CurrentDateTimeDemo values(now()); Query OK, 1 row affected (0.20 sec)Now you can check the current date/time has been inserted or not −mysql> select *from CurrentDateTimeDemo;The following ...
