With the code that is being tested is:

import java.util.Random;
public class GVdate
{
private int month;
private int day;
private int year;

private final int MONTH = 1;
private final int DAY = 9;
private static Random rand = new Random();

/**
* Constructor for objects of class GVDate
*/
public GVdate()
{

this.month = rand.nextInt ( MONTH) + 1;
this.day = rand.nextInt ( DAY );

}

public int getMonth()
{return this.month;

}

public int getDay()
{return this.day;

}

public int getYear()
{return this.year;

}

public String toString()
{String monthString = "0" + this.month;
int monthLength = monthString.length();

String dayString = "0" + this.day;
int dayLength = dayString.length();

return (
"\t" +
monthString.substring( monthLength-2 ) + ":" +
dayString.substring( dayLength-2 ) + " " +
this.year
);

}

public boolean isMyBirthday()
{return month == 8 && day == 31 && year == 2001;

}

public void setMonth( int m )
{
month=m;
}

public void setDay( int d )
{
day=d;
}

public void setYear( int y)
{
year=y;

}

public void setDate (int m, int d, int y)
{ year = y;
month = m;
day = d;

}
}

How do I fix the errors so that it runs?

int errors = 0;
        System.out.println ("Testing begings");

        //********** phase 1 testing ************

        // testing the default constructor 
        GVdate today = new GVdate();
        if (today.getMonth() != 10){
            System.out.println("month should be 10");
            errors++;
        }
        if (today.getDay() != 12){
            System.out.println("day should be 12");
            errors++;
        }
        
        // TO DO: test the year
    

        // testing constructor 2
        GVdate theDay = new GVdate(1, 10, 1995);
        // TO DO: complete the checks for month, day and year

        // testing setter methods 
        //testing setMonth
        theDay.setMonth(8);
        // TO DO: complete the code to check for month
        // TO DO: finish testing setDay and setYear
        // TO DO: test the toString method

        System.out.println("Errors: " + errors);
        System.out.println ("Testing ends");
    }  

}
