Java compiler error

Well, let me give an example of what my problem is. Refer to the following two classes.

public class Character
{
  private String name;

  public Character(String name)
  {
    this.name = name;
  }
}

public class TestCharacter
{
  Character mine = new Character("Cloud");
}

I know that my program dosen't "do" anything, I just wanted to give an example of what error my compiler is goving me. This is the error that my compiler gives me.

TestCharacter.java:3: cannot resolve symbol
symbol  : constructor Character (java.lang.String)
location: class java.lang.Character
  Character mine - new Character("Cloud");
                   ^
1 error

The classes compile perfectly on two other computers, one running Windows98SE and another running WindowsXP Home Edition. I believe that the problem came up after I installed Office XP on my computer, which is running Windows98SE. Yes, my compiler used to work just fine but I did something and it is giving me this error.

When I type in "echo %CLASSPATH%" in command prompt it give me the result:

"C:\WINDOWS\SYSTEM\QTJava.zip""

Is this correct?

EDIT: Formatted my C: drive, which only had windows files on it, and reinstalled windows98se. The problem is fixed now. The only think that I can think of that caused the problem was installing office XP. Well, the compiler works perfectly now!
