It is possible to address an I/O port as if it were a memory location. For example, let us say, the chip select pin of an I/O port chip is activated when address = FFF0H, IO/M* = 0, and RD* = 0. This is shown in the following fig.In this ... Read More

At first, we have set the mathematical expressions:String one = "10+15*20-5/5"; String two = "3+5-6"; String three = "9+2*(6-3+7)";To parse mathematical expression, use Nashorn JavaScript in Java i.e. scripting. Nashorn invoke dynamics feature, introduced in Java 7 to improve performance.For scripting, use the ScriptEngineManager class for the engine:ScriptEngineManager scriptEngineManager = ... Read More

Use the add() method to insert elements in the Stream.Builder. The element to be added is a parameter for the add().The following is the syntax:default Stream.Builder add(T t)Here, t is the element to be added.Import the following package for the Stream.Builder class in Java:import java.util.stream.Stream;At first, create Stream.Builder:Stream.Builder builder = ...

The build() method of the LongStream.Builder class builds the stream and returns the built stream. The following is the syntax:LongStream build()Import the following package for the LongStream.Builder class in Java:import java.util.stream.LongStream;Declare a LongStream.Builder and add elements:LongStream.Builder builder = LongStream.builder(); builder.add(24000L); builder.add(47470L); builder.add(12999L);Now, use the build() method to build the ...

Generally, a processor like 8085, to address one I/O port by sending out 8-bit port address and IO/M* = 1. For example, let us say, the chip select pin of an I/O port chip is activated when 8-bit address = F0H, IO/M* = 1, and RD* = 0. This is ... Read More

Two MonthDay objects can be compared using the compareTo() method in the MonthDay class in Java. This method requires a single parameter i.e. the MonthDay object to be compared.If the first MonthDay object is greater than the second MonthDay object it returns a positive number, if the first MonthDay object ...

The MonthDay can be formatted with the specified formatter using the format() method in the MonthDay class in Java. This method requires a single parameter i.e. the MonthDay object to be formatted and it returns the formatted MonthDay with the specified formatter.A program that demonstrates this is given as followsExample Live ...
