Inputting date parameter into Apex test class

Hi All,

I'm attempting a Trailhead challenge and it requires me to create a test class on a method that takes date parameters. See below:
  
public class VerifyDate {
	
	//method to handle potential checks against two dates
	public static Date CheckDates(Date date1, Date date2) {
		//if date2 is within the next 30 days of date1, use date2.  Otherwise use the end of the month
		if(DateWithin30Days(date1,date2)) {
			return date2;
		} else {
			return SetEndOfMonthDate(date1);
		}
	}
	
	//method to check if date2 is within the next 30 days of date1
	private static Boolean DateWithin30Days(Date date1, Date date2) {
		//check for date2 being in the past
        	if( date2 < date1) { return false; }
        
        	//check that date2 is within (>=) 30 days of date1
        	Date date30Days = date1.addDays(30); //create a date 30 days away from date1
		if( date2 >= date30Days ) { return false; }
		else { return true; }
	}

	//method to return the end of the month of a given date
	private static Date SetEndOfMonthDate(Date date1) {
		Integer totalDays = Date.daysInMonth(date1.year(), date1.month());
		Date lastDay = Date.newInstance(date1.year(), date1.month(), totalDays);
		return lastDay;
	}

}

...this is my first test method:
  
@istest private class TestVerifyDate {

    @istest static void method1crit1 (){
        Date method1res1 = VerifyDate.CheckDates(12/15/15,12/16/15);
        system.assertEquals(12/16/15,method1res1);
    }
}
...and I am getting the following error in the problems tab of the Dev Console:

"Method does not exist or incorrect signature: VerifyDate.CheckDates(Integer, Integer)"

Please help.

Thanks,

Mark

Apex Basics and Database Module along the Beginner Developer Trail: List Challenge

Hi All,

I am working with a fresh DE org with no customizations and I am continually failing the first unit of the Apex Basics and Database Module along the Beginner Developer Trail.

The Challenge is below:

Create an Apex class that returns an array (or list) of formatted strings ('Test 0', 'Test 1', ...). The length of the array is determined by an integer parameter.
- The Apex class must be called 'StringArrayTest' and be in the public scope.
- The Apex class must have a public static method called 'generateStringArray'.
- The 'generateStringArray' method must return an array (or list) of strings. Each string must have a value in the format 'Test n' where n is the index of the current string in the array. The number of returned strings is specified by the integer parameter to the 'generateStringArray' method.

...and this is my failing solution: 
public class StringArrayTest {
    
	public static void generateStringArray (Integer rs){
        list<string> stringarray = new list<string>();
        
        for(Integer n=0;n < rs;n++){
            stringarray.add('Test ' + n);
        }
        
        string a = stringarray[0];
        string b = stringarray[1];
        string c = stringarray[2];
        string d = stringarray[3];
        
        system.debug(a);
        system.debug(b);
        system.debug(c);
        system.debug(d);
    
        integer y = stringarray.size();
        system.debug(y);
        
}
}

...and here is the failure message:

"Challenge Not yet complete... here's what's wrong:
Executing the 'generateStringArray' method failed. Either the method does not exist, is not static, or does not return the proper number of strings."

...All my returning debug values seem to be correct. Please help, if possible.

Thanks!

Mark
