Below programs illustrate the use of setMonths() method.
Example 1:

// Java code to demonstrate setMonths() 
  
import java.text.DateFormatSymbols; 
import java.util.Locale; 
  
public class DateFormat_Main { 
    public static void main(String args[]) 
    { 
  
        // Initialising DateFormatSymbols object 
        DateFormatSymbols format 
            = new DateFormatSymbols( 
                new Locale("en", "US")); 
  
        // Taking the default short weekdays 
        String[] Days = format.getMonths(); 
  
        // Displaying the original 
        System.out.println("Original: "); 
        for (int i = 0; i < Days.length; i++) { 
            System.out.println(Days[i] + "  "); 
        } 
  
        // Taking an alternative names with 
        // additional random strings 
        String[] modDays = { "GEEK", "FOR", 
                             "GEEK", "DECEMBER", 
                             "NOVEMBER", "JAN", 
                             "FEB" }; 
  
        // Setting the default into modified 
        format.setMonths(modDays); 
  
        // Displaying the modified string 
        String[] modifiedDays 
            = format.getMonths(); 
  
        System.out.println("Modified: "); 
        for (int i = 0; i < modifiedDays.length; i++) { 
            System.out.println(modifiedDays[i] + "  "); 
        } 
    } 
}

public class DateFormat_Main { 
    public static void main(String args[])

        // Initialising DateFormatSymbols object 
        DateFormatSymbols format 
            = new DateFormatSymbols( 
                new Locale("en", "US"));

        String[] Days = format.getMonths(); 
  
        // Displaying the original 
        System.out.println("Original: "); 
  
        for (int i = 0; i < Days.length; i++) { 
            System.out.println(Days[i] + "  "); 
        } 
  
        // Taking an alternative names with 
        // additional random strings 
        String[] modDays = { "123", "456", 
                             "JAN", "FEB", 
                             "NOV", "Dec", 
                             "May" }; 
  
        // Setting the default into modified 
        format.setMonths(modDays); 
  
        // Displaying the modified string 
        String[] modifiedDays 
            = format.getMonths(); 
  
        System.out.println("Modified: "); 
        for (int i = 0; i < modifiedDays.length; i++) { 
            System.out.println(modifiedDays[i] + "  "); 
        }
