Java DateTime, Calendar : Exercise-4 with Solution

Write a Java program to get the minimum value of year, month, week, date from the current date of a default calendar.

Sample Solution:

Java Code:

import java.util.*;
public class Exercise4 {
 public static void main(String[] args)
    {
     // Create a default calendar
        Calendar cal = Calendar.getInstance();
		System.out.println();
		System.out.println("\nCurrent Date and Time:" + cal.getTime());		
		int actualMaxYear = cal.getActualMinimum(Calendar.YEAR);
		int actualMaxMonth = cal.getActualMinimum(Calendar.MONTH);
		int actualMaxWeek = cal.getActualMinimum(Calendar.WEEK_OF_YEAR);
		int actualMaxDate = cal.getActualMinimum(Calendar.DATE);
		
		System.out.println("Actual Minimum Year: "+actualMaxYear);
		System.out.println("Actual Minimum Month: "+actualMaxMonth);
		System.out.println("Actual Minimum Week of Year: "+actualMaxWeek);
		System.out.println("Actual Minimum Date: "+actualMaxDate+"\n");
		System.out.println();		
	  }
}

Sample Output:

Current Date and Time:Tue Jun 20 14:29:35 IST 2017                                                            
Actual Minimum Year: 1                                                                                        
Actual Minimum Month: 0                                                                                       
Actual Minimum Week of Year: 1                                                                                
Actual Minimum Date: 1

N.B.: The result may varry for your system date and time.
