为什么我会收到“找不到符号"?编译时java程序出错?

I am trying to return the value of my boolean variable localFound at the end of my code but when I compile, I get an error that says it cannot find the symbol. I know this is an error that deals with the scope of the variable, but I do not know how to fix it. How do I get my program to return the correct value? Thanks.

public static boolean addIfNotEmpty(DvdTreeNode root, String movieToCommand) {

  if (root == null) {
    return false;
  }
  addIfNotEmpty(root.getRight(), movieToCommand);
  if (root.getItem().getTitle().equalsIgnoreCase(movieToCommand)) {
    root.getItem().addCopy();
    System.out.println("You have added another copy of ""
    + movieToCommand
    + "" to the inventory.");
    boolean localFound;
    localFound = true;
  }
  addIfNotEmpty(root.getLeft(), movieToCommand);
  return localFound;
} // end addIfNotEmpty 

推荐答案

localFound 未在您的 return 语句的范围内定义.它只存在于您的 if 语句中.
