converting characters to Objects question

[Alienz]

I'm writting a program that at some point has to push onto a stack or enqueue in a queue characters from a string. I tried converting the characters to objects before pushing/enqueueing but the compiler complains about inconvertible types. Enough talking here is the code (the lines in bold are the ones giving me errors):

public class Prog3
{//start



	public static void main ( String args [] )
	{//begin main

		StackListBased stack1 = new StackListBased();						// create new stack
		QueueListBased queue1 = new QueueListBased();						// create new queue

		Character dollarSign = new Character ('$');							// store dollar sign in dollarSign
		Character compareStack = new Character ('s');						//character for comparison purposes
		Character compareQueue = new Character ('q');						//character for comparison purposes

		String sentence;													// create empty string
		int strLength;														// integer variable to store length of string
		int SignCount = 0;													//store position of $ in string
		int count = 0;														//counter used for queue insertion
		int count2 = 0;														// counter used for stack pushing
		boolean good = true;												//boolean value




		System.out.println ("Enter a string seperated by a $ sign: ");		//prompt user to enter a formula
		sentence = Keyboard.readString();									//store input in sentence

		strLength = sentence.length();										//return the length of string and save in strLength



		//determine position of $ and store in SignCount
		while ( sentence.charAt ( SignCount ) != dollarSign.charValue())
		{
			 SignCount ++;
		}

		//insert characters before $ in queue
		while ( count < SignCount )
		{
			queue1.enqueue( (Character)sentence.charAt ( count ) );
			count ++;
		}

		count2 = SignCount + 1;

		//push character after $ onto stack
		while ( count2 <= strLength )
		{
			stack1.push(  (Character)sentence.charAt ( count2 ) );
			count2 ++;
		}

		//pop stack and dequeue queue while both are not empty
		while ( !stack1.isEmpty() && !queue1.isEmpty() )
		{


			compareStack = (Character)stack1.peek();						//peek at stack and store peeked value here
			compareQueue = (Character)queue1.peek();						//peek at queue and store peeked value here

			// if peeked values are equal pop stack and dequeue queue
			if ( compareStack.charValue() == compareQueue.charValue() )
			{
				stack1.pop();
				queue1.dequeue();
			}
			else
			{
				//if peeked values are not equal change boolean value and break
				good = false;
				break;
			}

		}

		//display
		if ( good == true )
			System.out.println ("String balanced." );
		else
			System.out.println ("String unbalanced." );

	}
}

And here is the errors I got when I compiled:

[compiler]
C:\Documents and Settings\battlefield\Desktop\prog3-java\Prog3.java:47: inconvertible types
found : char
required: java.lang.Character
queue1.enqueue( (Character)sentence.charAt ( count ) );

C:\Documents and Settings\battlefield\Desktop\prog3-java\Prog3.java:56: inconvertible types

required: java.lang.Character
stack1.push( (Character)sentence.charAt ( count2 ) );
^
2 errors

I included the zip file (pro3-java) which has prog3 in it and all the other classes. You just need to compile/run prog3.java if you want to check it out that is. Your help will be a lot appreciated

Instead of this:

(Character)sentence.charAt ( count )

try this:

new Character( sentence.charAt ( count ) )

You can't cast a primative char to a Character Object, but you can create a Character Object from a primative char.
