Thread: Really need help on assignment

I am a high school student and my I have to finish a lab by tomorrow. I would normally try to figure this out for myself however I am also studying for a AP European History exam, a chemistry exam, and working on an analysis for English. Basically I am swamped and completely panicking right now. It would really help if one of the programmers here could give me the code for the problems below.

public class MiscCollectionOfFunMethodsII {
 
 
  	public static String carRentalCode(String licensePlate) {
	// precondition:	licensePlate is a valid plate as described at
	//                  [url]http://www.apcomputerscience.com/syllabus/la3_carRental.pdf[/url]
	// postcondition:	return the car rental code for the licensePlate as described above
           int i = licensePlate.charAt(0)+licensePlate.charAt(1);
           return ""+i;
    }  
 
 
	public static double[] magicSquares(int n) {
    // A magic square is a number that is both a perfect square, and the sum of consecutive
    //  integers starting with 1.  For example, 36 is a magic square, since 6 * 6 = 36,
    //  and 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 = 36 
 
	// precondition: 	n is a positive integer 
    // postcondition: 	return a vector whose size is exactly n
    //  and contains, in order, the first n magic squares
 
    //    The first Magic square is 1
 
         return new double[2];
    }
 
    public static int uglyNumberGetter(int n) {
    // precondition: 	n >= 1 (but not too big as to make it impossible to get the nth ugly number 
    //                  I don’t know what that is yet but I won’t let it get that big)
    //                  look here: [url=http://acm.uva.es/problemset/v1/136.html]Ugly Numbers[/url]
    //                  Ugly numbers are numbers whose only prime factors are 2, 3 or 5
    // postcondition:	return the nth ugly number
 
       return -13121;
    }
 
    public  static  void  compact  (Object[] vec, Object item) {
    //  precondition:  vec contains objects; vec.length >= 1
    //  postcondition:  all elements x in vec, s.t. x.equals(item) have been “removed”.
    //	all remaining elements are in their same original relative order and are at the 
    //	beginning of vec the remaining locations at the end of the vec should be explicitly 
    //	set to null
 
      // put code here
 
    }
 
    public static int[ ] primeNumberGenerator(int from, int to) {
    // precondition:	from <= to <= 10,000,000
    // postcondition:	a 2-element vector of ints is returned, 
    //	where location 0 contains the number of primes in the given range and 
    //	location 1 contains the last prime generated in the given range
    //  If from && to are prime, they count as primes (inclusive range)
 
         return new int[2];
    }
 
 
}

Please someone help I am completely panicking right now
