Here are parts i remember: a guy walking at night sees a guy on a roof, and the same guy over on the ground, he figures he is messing with people using his twin brother. Meets stranger, sees him regularly, he chews every bite as if it were each a meal of its own, makes him eat slower. Eating something out of a bowl and finishes it quickly realizing he didnt appreciate it. Has a dream starting with him as a kid kicking clothes under his bed, of his entire life but if he never met the roof guy. Finds in mailbox from the stranger that says roof secrets or similar. Cover is like a guy half inisible with a bag next to a gas station? Please help. :)

There are a few errors, one is that I need the variable "inputs" to be recognized outside of the for loop, it is because it was created inside the for loop, I was wondering if there was a way to go around that or a different approach I could try. Also, there is a minor issue with the char variables at the end. They do not like to be in if statements and be treated like Strings. How do you use char's in if statements like the way I need to?

else if(nameBox[i].getText().equalsIgnoreCase('T')){

}

else if(nameBox[i].getText().equalsIgnoreCase('E')){

howManyExcused = howManyExcused + 1;

}

}

//goes through the list of A's, T's, E's, and Blanks,

//and for each one, adds 1 to a corresponding variable

JOptionPane.showMessageDialog

(null, "# of Absent Students: " + howManyAbsent

+ "# of Excused Students: " + howManyExcused);

//prints out a page with the number of each student who

//was not on time.

}

}

The problem is that the print statement JOptionPane does not like to recognize that the word input exists, because it was initiated inside of the for loop. Think you can help? it is not finished yet, in case you are wondering. But this is everything that I have so far.

My friend asked me if I knew how to sort an array, so I used the sort method, but he wasn't impressed. this is my attempt with loops, and you get to chose the number of numbers in the array as well. (just because). anyone know whats wrong? p.s. it will do everything up to finding the highest number, and that part is tested as well, so the problem is most likely the part that is supposed to sort the array, which is that big nasty pile of four loops and if statements.

It should arrange a set of numbers from least to greatest. But it doesn't. And I don't know why. see what you can do, I added comments to make it easier to figure out what is happening. When I run it in NetBeans, it asks for the number of numbers, and even asks for the specific numbers, but then it errors, so I suppose the problem could be anywhere from the finding of the highest number to the end. Thanks in advance!

it is supposed to ask how many numbers you'd like, which it does, then have you input specific numbers, the amount you chose, then tell you the first two numbers you chose, it has trouble assigning the integers to the array. any ideas?

package inorder.without.cheats;

import javax.swing.JOptionPane;

public class InOrderWithOutCheats {

public static void main(String[] args) {

int howManyNumbers = Integer.parseInt (JOptionPane.showInputDialog

(null, "how many numbers would you like to chose?"));

//gets number of numbers, stores number in howManyNumbers

if (howManyNumbers <= 0){

JOptionPane.showMessageDialog

(null, "You Must Enter A Positive Number Greater "

+ "Than 0!", "Hey!", JOptionPane.ERROR_MESSAGE);

}

//prevents number from being <= 0

int[] array = new int[howManyNumbers];

for (int i = 0; i < howManyNumbers; i++){

int choseNumber = Integer.parseInt

(JOptionPane.showInputDialog

(null, "Number #" + i));

array[i] = choseNumber;

}

/*supposed to ask for each number, the amount you chose, and assign them to an array*/

JOptionPane.showMessageDialog

(null, "number 1: " + array[0] + " number 2: " + array[1]);

//checks if it actually assigned them correctly, which it doesn't.

}

}

package inorder.without.cheats;

import javax.swing.JOptionPane;

//imports what is needed for the dialog box (JOptionPane)

public class InOrderWithOutCheats {

public static void main(String[] args) {

int howManyNumbers = Integer.parseInt (JOptionPane.showInputDialog

(null, "how many numbers would you like to chose?"));

/*saves input to the question "how many numbers would you like to chose?" into the variable howManyNumbers*/

if (howManyNumbers <= 0){

JOptionPane.showMessageDialog

(null, "You Must Enter A Positive Number Greater "

+ "Than 0!", "Hey!", JOptionPane.ERROR_MESSAGE);

}

/*makes sure the inputed number of numbers in the array is a positive number greater than 0*/

int[] array = new int[howManyNumbers];

for (int i = 1; i <= howManyNumbers; i++){

int choseNumber = Integer.parseInt

(JOptionPane.showInputDialog

(null, "Number #" + i));

array[i] = choseNumber;

}

/*assigns (or tries to at least) the inputed numbers to the question "Number # 1" "Number # 2"... to the array array*/

JOptionPane.showMessageDialog

(null, "number 1: " + array[0] + " number 2: " + array[1]);

/*confirms that it actually did what it is supposed to by listing off two of the numbers that were (supposed to be) assigned to the array. and fails*/

Eventually it should put the numbers in an array in order with out the use of the "sort" shortcut.

But for now not even this will do what i want, i just want this bit of code to ask how many numbers you would like in an array, ask what numbers are actually are in this array, then assign the chosen numbers to an array, and then just to check if it works, display the first two numbers. think you can help?

String a = JOptionPane.showInputDialog ("a ");

String b = JOptionPane.showInputDialog ("b ");

int quadratic2 = -b - rt / 2a;

JOptionPane.showMessageDialog ("answere one = " + quadratic1

+ " answere two = " + quadratic2);
