At the end of the state T2 in a machine cycle, 8085 processor senses the Ready input pin. If it is logic 0, 8085 processors enter the Twait state, else it enters to the T3 state. The Ready input is permanently fixed to logic 1. The memory chips and the Input Output ports in the system same speed with 8085. Else appropriate number of wait states should be generated by the external circuit. In fact, in the ALS kit the Ready pin should be fixed to logic 1As an example, we check up if the 27128A-20 16K×8 EPROM chip are used ... Read More
Before getting into example, we should know what sqlite data base in android is. SQLite is an open source SQL database that stores data to a text file on a device. Android comes in with built in SQLite database implementation. SQLite supports all the relational database features. In order to access this database, you don't need to establish any kind of connections for it like JDBC, ODBC etc.This example demonstrate about How to use distinct and count t in Android sqliteStep 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required ...

The range of values for a ChronoField can be obtained using the range() method in the LocalDateTime class in Java. This method requires a single parameter i.e. the ChronoField for which the range of values is required and it returns the range of values.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; import java.time.temporal.ChronoField; import java.time.temporal.ValueRange; public class Main { public static void main(String[] args) { LocalDateTime ldt = LocalDateTime.parse("2019-02-18T11:19:50"); System.out.println("The LocalDateTime is: " + ldt); ValueRange dowRange = ldt.range(ChronoField.DAY_OF_WEEK); System.out.println("The range of DAY_OF_WEEK: ...

The limit() method of the DoubleStream class returns a stream consisting of the elements of this stream, truncated to be no longer than max in length. The max is a parameter of the limit() method.The syntax is as followsDoubleStream limit(long max)Here, max is the number of elements the stream should be limited to.To use the DoubleStream class in Java, import the following packageimport java.util.stream.DoubleStream;Create a DoubleStream and add elementsDoubleStream doubleStream = DoubleStream.of(10.8, 20.7, 25.8, 35.7, 78.2, 89.7, 67.8, 86.3);Now, to display n number of elements, set it as a parameter value for limit()doubleStream.limit(5)The following is an example to implement DoubleStream ...

To rename a collection in MongoDB, you can use renameCollection() method. The syntax is as follows −db.yourOldCollectionName.renameCollection('yourNewCollectionName');To understand the above syntax, let us list all the collections from database sample. The query is as follows −> use sample; switched to db sample > show collections;The following is the output −copyThisCollectionToSampleDatabaseDemo deleteDocuments deleteDocumentsDemo employee informationAboutDelete internalArraySizeDemo prettyDemo selectWhereInDemo sourceCollection updateInformation userInformationNow change collection name ‘informationAboutDelete’ to ‘deleteSomeInformation’. The query is as follows to change the collection name.> db.informationAboutDelete.renameCollection('deleteSomeInformation'); { "ok" : 1 }Here is the query to check the collection name has been renamed to 'deleteSomeInformation' −> show collections;The following is ...

In this section, we will see how to tokenize strings in C. The C has library function for this. The C library function char *strtok(char *str, const char *delim) breaks string str into a series of tokens using the delimiter delim.Following is the declaration for strtok() function.char *strtok(char *str, const char *delim)It takes two parameters. The str - The contents of this string are modified and broken into smaller strings (tokens), and delim - This is the C string containing the delimiters. These may vary from one call to another. This function returns a pointer to the first token found ... Read More
