This instruction is very similar to the SUB instruction. The only difference is that it does not update the value of Accumulator after executing. So after comparing, if the CY flag is set, it means that the first number is smaller, and the second one is largerInputFirst inputAddressData......8000FD800123......second inputAddressData......800059800175......Flow DiagramProgramAddressHEX CodesLabelMnemonicsCommentsF00021, 00, 80LXI H, 8000HPoint to the first ...

A method with variable length arguments(Varargs) in Java can have zero or multiple arguments. Variable length arguments are most useful when the number of arguments to be passed to the method is not known beforehand. They also reduce the code as overloaded methods are not required.A program that demonstrates this is given as follows:Example Live Demopublic class Demo { public static void Varargs(String... str) { System.out.println("Number of arguments are: " + str.length); System.out.println("The argument values are: "); for (String s : str) System.out.println(s); } ...

You can get year out of timestamp using YEAR() function. The syntax is as follows −SELECT yourColumnName FROM yourTableName WHERE YEAR(yourTimestampColumnName)='yourYearValue’';To understand the above syntax, let us create a table. The query to create a table is as follows −mysql> create table getYearOut -> ( -> Id int NOT NULL AUTO_INCREMENT, -> Name varchar(10), -> yourTimestamp timestamp default current_timestamp, -> PRIMARY KEY(Id) -> ); Query OK, 0 rows affected (1.56 sec)Insert some records in the table using INSERT command−mysql> insert into getYearOut(Name, yourTimestamp) values('John', now()); Query OK, 1 row affected (0.26 sec) ...
