To work with the GregorianCalendar class, import the following package.import java.util.GregorianCalendar;Firstly, create a GregorianCalendar object.GregorianCalendar calendar = new GregorianCalendar();Now, set the above-created object to a date. Here 0 is for 1st month.calendar.set(2018, 0, 25);The following is an example.Example Live Demoimport java.util.GregorianCalendar; import java.util.Calendar; import java.util.Date; public class Demo { public static void main(String[] args) { GregorianCalendar calendar = new GregorianCalendar(); // 0 is for 1st month calendar.set(2018, 0, 25); System.out.println("" + calendar.getTime()); } }OutputThu Jan 25 16:51:24 UTC 2018
For GregorianCalendar class, import the following package.import java.util.GregorianCalendar;Create an object.GregorianCalendar calendar = new GregorianCalendar();To get the day of the week, use the following field.GregorianCalendar.DAY_OF_WEEKThe following is an example.Example Live Demoimport java.util.Calendar; import java.util.GregorianCalendar; public class Demo { public static void main(String[] a) { GregorianCalendar calendar = new GregorianCalendar(); System.out.println("Day of Week = " + calendar.get(GregorianCalendar.DAY_OF_WEEK)); System.out.println("Date = " + calendar.get(GregorianCalendar.DATE)); System.out.println("Month = " + calendar.get(GregorianCalendar.MONTH)); System.out.println("Year = " + calendar.get(GregorianCalendar.YEAR)); } }OutputDay of Week = 2 Date = 19 Month = 10 Year = ...

Phi is the basis for the Golden Ratio, Section or Mean. The value of Phi ( Φ ) is 1.618033988749895. It has many unusual mathematical properties.The Golden ratio is a special number found by dividing a line into two parts so that the longer part divided by the smaller part is also equal to the whole length divided by the longer part. It is often symbolized using phi, after the 21st letter of the Greek alphabet.The ratio or proportion, determined by Phi (1.618 …) was known to the Greeks as the “dividing a line in the extreme and mean ratio” ...

For GregorianCalendar class, import the following package.import java.util.GregorianCalendar;Firstly, let us display the current date and time.GregorianCalendar cal = (GregorianCalendar) GregorianCalendar.getInstance(); System.out.println("Current date: " + cal.getTime());Now, modify the date. Here we are adding two days to the month using the add() method.cal.add((GregorianCalendar.MONTH), 2);Example Live Demoimport java.util.Calendar; import java.util.GregorianCalendar; public class Demo { public static void main(String[] a) { GregorianCalendar cal = (GregorianCalendar) GregorianCalendar.getInstance(); System.out.println("Current date: " + cal.getTime()); cal.add((GregorianCalendar.MONTH), 2); System.out.println("Modified date: " + cal.getTime()); } }OutputCurrent date: Mon Nov 19 17:52:55 UTC 2018 Modified date: Sat Jan ...

For GregorianCalendar class, import the following package.import java.util.GregorianCalendar;Create an object.GregorianCalendar cal = (GregorianCalendar) GregorianCalendar.getInstance();Now, use the following field and add() method with a negative one (-1) to display the previous year.cal.add((GregorianCalendar.YEAR), -1)Example Live Demoimport java.util.Calendar; import java.util.GregorianCalendar; public class Demo { public static void main(String[] a) { GregorianCalendar cal = (GregorianCalendar) GregorianCalendar.getInstance(); System.out.println("Current date: " + cal.getTime()); // previous year cal.add((GregorianCalendar.YEAR), -1); System.out.println("Modified date: " + cal.getTime()); } }OutputCurrent date: Mon Nov 19 18:05:49 UTC 2018 Modified date: Sun Nov 19 18:05:49 UTC 2017
To get the time format, use the DateFormat class and create a new object.DateFormat dateFormatter = new SimpleDateFormat("hh.mm.ss a");Now, parse the time.dateFormatter.parse("12.55.20 PM");Example Live Demoimport java.text.DateFormat; import java.text.SimpleDateFormat; import java.util.Date; public class Main { public static void main(String[] argv) throws Exception { DateFormat dateFormatter = new SimpleDateFormat("hh.mm.ss a"); System.out.println("Parse Time..."); Date dt = (Date) dateFormatter.parse("12.55.20 PM"); System.out.println(dt); } }OutputParse Time... Thu Jan 01 12:55:20 UTC 1970
UseSimpleDateFormat('dd-MMM-yy') for string date.Format dateFormatter = new SimpleDateFormat("dd-MMM-yy");For above class, do not forget to import the following package, else an error would be visible.import java.text.SimpleDateFormat;Now, parse the date.Date dt = (Date) dateFormatter.parseObject("20-Nov-18");Example Live Demoimport java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; public class Main { public static void main(String[] argv) throws Exception { Format dateFormatter = new SimpleDateFormat("dd-MMM-yy"); // parse Date dt = (Date) dateFormatter.parseObject("20-Nov-18"); System.out.println("Date = "+dt); } }OutputDate = Tue Nov 20 00:00:00 UTC 2018

The processor on a single chip is called a Microprocessor which can process micro-instructions. Instructions in the form of 0s and 1s are called micro-instructions. The microprocessor is the CPU part of a microcomputer, and it is also available as a single integrated circuit. Thus as main components, the microprocessor will have the Control Unit (CU) and the Arithmetic Logic Unit (ALU) of a microcomputer. An example is Intel 8085 microprocessor. In addition to the microprocessor features, a microcomputer will have the following additional features −ROM / PROM / EPROM / EEPROM for storing programRAM for storing data, intermediate results, ...
