新人求助关于java.lang.StackOverflowError的异常问题

public class ProcessRow {
Properties source= new Properties();
{
try {
FileInputStream fis = new FileInputStream(new File(
inputPropertieName()));
InputStreamReader isr = new InputStreamReader(fis, "UTF-8");
source.load(isr);
fis.close();
} catch (Exception e) {
// throw new ExceptionInInitializerError(e);
}
}

public  String filterAlphabet(String alph) {
    alph = alph.replaceAll("[^(A-Z)]", "");
    return alph;
}

public String Pname() {
    UseProcess f=new UseProcess();
    String hai = f.fileName;
    String a = filterAlphabet(hai);
    String b = hai.substring(hai.indexOf(a), hai.indexOf(a) + 6);
    return b;

}

public  String inputPropertieName() {
    /*
     * System.out.println("请输入配置文件名称:"); Scanner a = new Scanner(System.in);
     * String propertieName = a.next();
     */
    // a.close();
    ProcessRow a = new ProcessRow();
    String propertieName = a.Pname();
    return propertieName;
}

    ProcessRow构造函数调用inputPropertieName()
    inputPropertieName()内又调用ProcessRow a = new ProcessRow();造成循环调用,无限递归
