маленькие программы в ibm architect

[bido]

Помогите плиз сделать хотя бы несколько из этих заданий, а то я никак не могу разобраться.

1. Write a program that reads an integer max from the keyboard. If the number are greater than 100, the program writes a random integer to the screen, taken from interval [0;max] (both numbers included). Otherwise it prints an error-message containing the number written by the user.

2. Write a method public String numberToText (int t), thattakes a parameter t between 1 and 6 and returns a text, corresponding to the number. Ex: if t equals 2. it will return "Two". If the number recieved is outside the interval, it returns the text "Outside interval".
Yand in: Just a method (not a whole program!)

3. Write a program that reads numbers from the keyboard until it recieves a number<0. It then prints the sum of the numbers read before the 'stop'-number.

4. As you should know,there are 3 different loop-constructions in Java. Rewrite at least one of the following loops to the 2 other possible forms. Please state which one you have rewritten.
A: for(int i=-2; i<10;i++)
system. out.println(i);

B: int i = 10
while(0<i)
{
System.out.println(i);
i/=2;
}

C: int i = 3
do
{
System.out.println(i);
i+=3;
} while(i<=10);
