Java图形用户界面程序设计作业

实验要求：英语完型填空测试

编写一个文本文件“English.txt”，该文件的每一行字符串是符号“＃”。第一个语言符号是一个练习填空的英语句子，第2个到第5个语言符号是供选择的答案，第6个是正确的答案，如下所示：

#1.Take an umbrella with you in case #it will rain#it rains#it raining#it rained#it rains#

#2.He is no longer the honest man he has#who#whom#which#that#that#

… …

endend

要求每次读取文本文件的一行，然后使用字符串解析器把语言符号分解出来。第一个语言符号放在文本框中，其余四个语言符号作为选择框的名字，供选择答案用。最后一个语言符号是答案，根据选择的情况来给出分数。每当做完一个题目之后（即选择框发生事件之后），就判定分数。单击“下一题目”按钮，就再读取一行。当读到最后一行字母endend时，就关闭流，通知用户练习已完成。当单击“重新练习”按钮时，程序重新将流指向文件“English.txt”。
请大家给出详细的解答!或者发到邮箱w4222475@163.com
效果图如下:
