Question

在输入时，我的文本字段开始删除输入并抛出java.io.EOFException。在我的keyReleased事件处理程序中，count仍为0;处理程序没有执行count++。

有人可以建议我做错了什么以及如何解决这个问题？

public void keyReleased(KeyEvent e) {
    int count = 0;
    result = null;
    setVisible(false);
    matchingVector.clear();
    String searchTerm = dialog.getField(getSearchFieldNumber());
    System.out.println(searchTerm);
    if (searchTerm.length() > 0) {
        listModel.removeAllElements();
        System.out.println(recordVector.size());
        for (int i = 0; i < recordVector.size(); i++) {
            if (matchesCriteria(recordVector.get(i), searchTerm)) {
                matchingVector.add(recordVector.get(i));
                count++;
            }
        }
        if (count == 0) {
            clearFields();
            System.out.println("Bad-bad things happen here?");
        } else if (count == 1) {
            updateFields(matchingVector.get(0));
        } else if (count > 1) {
            validate();
            setVisible(true);
            setSize(WIDTH, Math.min(500, matchingVector.size() * ROW_HEIGHT));
        }
    } else {
        clearFields();
    }

}

你错过了matchesCriteria中其他人的左括号以下代码应该起作用 private boolean matchesCriteria(Record record, String searchTerm){ Booking booking = (Booking) record; if(booking.className.toLowerCase().contains(searchTerm.toLowerCase())){ listModel.addElement(booking.className); return true;} else{return false;} }

keyReleased处理程序中的java.io.EOFException和count问题
