Activity Hints by Mr. Stubbs

20 Bananas Hint

- If I add 5 to my counter everytime I press a button and I can't go over 20, then my counter has to accept button presses for all numbers until 16 - Reason: - 16+5 = 21 <- this is greater than 20! - one could say that (**MAJOR HINT ALERT**)

if (counter < 16 )
{

counter = counter + 5;

}

Loops Hint

- i++ means the exact same thing as i = i+1
- if you want to go up by 8 you would write i = i+8
- ex/

for( int i = 1000 ; i >=0 ; i = i - 100 )
{

System.out.println(i);
//this will make i go down by 100 each time

}

Error Checking Hints

- if you already know that the textfield is empty (txtInput.getText().isEmpty()) then why would we check for an "@" symbol? - remember "nesting" if statements

Random Numbers Hint

- you could use our formula to get a random number between 1 and 4

int random = (int) ((max - min + 1)*Math.random() + min);

- make if statements that correspond to the number generated (if random == 2)
