Two ArrayList can be compared to check if they are equal or not using the method java.util.ArrayList.equals(). This method has a single parameter i.e. an ArrayList that is compared with the current object. It returns true if the two ArrayList are equal and false otherwise.A program that demonstrates this is given as follows −Example Live Demoimport java.util.ArrayList; import java.util.List; public class Demo { public static void main(String[] args) { List aList1 = new ArrayList(); aList1.add("Sun"); aList1.add("Moon"); ...

You can use in-built function UNIX_TIMESTAMP() from MySQL to get the timestamps and the difference between two timestamps. The syntax is as follows −SELECT UNIX_TIMESTAMP(yourColumnName1) - UNIX_TIMESTAMP(yourColumnName2) as anyVariableName from yourTableName;To understand the above concept, let us create a table. The following is the query to create a table −mysql> create table DifferenceInSeconds −> ( −> FirstTimestamp TIMESTAMP, −> SecondTimestamp TIMESTAMP −> ); Query OK, 0 rows affected (0.93 sec)Insert some records in the table using insert command. The query is as follows −mysql> insert into DifferenceInSeconds values('2012-12-12 ... Read More

To get the Tail Set from TreeSet, use the tailSet() method. Tail Set begins from a point and returns the elements greater than the element set in the beginning.First, create a TreeSet and add elements −TreeSet set = new TreeSet(); set.add("78"); set.add("56"); set.add("88"); set.add("54"); set.add("76"); set.add("34");Now, get the Tail Set −SortedSet sorted = set.tailSet("56");The following is an example to get Tail Set from TreeSet −Example Live Demoimport java.util.*; public class Demo { public static void main(String args[]){ TreeSet set = new TreeSet(); set.add("78"); set.add("56"); set.add("88"); ...

To combine date and time column into a timestamp, you can use cast() function with concat().The syntax is as follows −select cast(concat(yourDateColumnName, ' ', yourTimeColumnName) as datetime) as anyVariableName from yourTableName;In the above concept, you will use cast() when your date and time is in string format. The cast() function can be used only for datetime. To understand the above syntax, let us create a table.The query to create a table is as follows −mysql> create table DateAndTimeToTimestamp −> ( −> Duedate date, −> DueTime time −> ); ... Read More

As we know that the Intel 8085 has five interrupt pins (TRAP, RST7.5, RST6.5, RST6.5 and INTR), but the Zilog Z-80 has only two interrupt pin. The NMI and INT . But it has superior interrupt structure compared to 8085.The INT InterruptIt is an active low, level triggered input interrupt. This is maskable and using DI instruction this can be disabled. When the interrupt pin is disabled, the Z-80 will not be interrupted if the IO devices enables the INT pin. Even after the reset, it will be disabled. So if we want that the MPU will be interrupted by the pin, there must be ... Read More
