201671010113 2016-2017-2 The Nineth week of Java programming

I feel this week's learning content is relatively small compared to the previous weeks, but the task volume is still quite a lot, the operation of the front pull a bit long, originally wanted to take a break on Sunday, in Friday after school began to write Java homework, the results to Sunday has not been completed, and because the front is a bit long, The task of doing the experiment before today forgot a lot. Feeling abnormal handling is very simple, but in the process of writing industry still found in addition to throw exception will check the exception is relatively simple, the other is still problematic, the Try-catch statement seems simple, but in the file I still under a kung fu, try statement to run through the file processing always, Variables set inside the file-handling code cannot be called outside of the try statement. Task Five task 6th log Breakpoint Self-study really difficult, code is very long, there are a lot of code can not understand, the cost of a great effort, the result is still not. The last Test mission, is really very serious in doing, the results in the name of the judge whether there is a number, the final result is always out, and then the name came out, score on the problem, I am powerless, the code results are as follows:

for (int i = 0; i < 4; i++)
{
if (Isdigist (Stu[i].getname (). CharAt (1)))
{
System.out.println ("Illegalnameexception:the first char of name must not be digit, name=" + stu[i].getname ());
Stu[i].setname (Stu[i].getname ());


}
Else
{
if ((Stu[i].getscore () > 0) && (Stu[i].getscore () < 100))
{
System.out.println (Stu[i].tostring ());
}
Else
{

System.out.println ("Illegalscoreexception:score out of range, score=" + stu[i].getscore ());
Stu[i].addscore (Stu[i].getscore ());
}

}
