title: Is there any way to use a non-static method in a static class?
body: <p>I'm trying to implement a simple spreadsheet using Java. It interacts with the user through some menus on the console, and a user can import a given file with some pre-made info about the spreadsheet to be created (lines, columns, and content of cells).
  I am trying to make a static class which I called Parser, and the goal of this class is to break down each line of the import into little pieces so I can then apply the correct methods to them (read the cell to which content is being added, and what type of content am I trying to add).</p>
  
  <p>I made my Parser static, because I want to use it without the need of instantiating a new object every time I need it (is this correct?). I have a specific method that is giving me trouble though. Whenever I receive input like this: <code>1;1|=2;3</code>it means that my cell 1;1 references the cell 2;3. I am telling the parser to return a new Reference(getCell(i,j)). This is because my Reference class constructor receives a Cell, but of course the java compiler tells me I cannot use a non-static method, which is the case of the getCell, inside that static class.</p>
  
  <p>So my question is: is there any way to overcome this problem? Any way to use a non-static method in a static class or should I instantiate a new Parser object when I try to read an import file? </p>
