I'm having an infinite while loop issue, no matter what I type in even if it is "Filed" or "Incomplete" the loop keeps re prompting and I can't figure out why.

```
strMajorSheet = JOptionPane.showInputDialog(null,"What is the advisee's major sheet status? (Filed/Incomplete)",
                "Advisee's Major Sheet",3);

if(strMajorSheet == "Filed" || strMajorSheet == "Incomplete")
                    {

                        switch(strMajorSheet)
                        {
                            case "Filed":
                                blnMajorSheet = true;
                            case "Incomplete":
                                blnMajorSheet = false;

                        }
                    }
                    else
                    {
                        while(strMajorSheet != "Filed" && strMajorSheet != "Incomplete")
                        {
                            strMajorSheet = JOptionPane.showInputDialog(null,"What is the advisee's major sheet status? (Filed/Incomplete)",
                                "Advisee's Major Sheet",3);

                        }

```
