簡單的JAVA學生管理系統(tǒng)代碼···

lListStudent students = new ArrayListStudent();

BufferedReader br = new BufferedReader(new FileReader("D:\student.txt"));

String tmpStr = br.readLine();

while(tmpStr != null){

int firstIndex = tmpStr.indexOf(" ");

int secondIndex = tmpStr.indexOf(" ",firstIndex + 1);

int thirdIndex = tmpStr.indexOf(" ", secondIndex + 1);

int forthIndex = tmpStr.indexOf(" ", thirdIndex + 1);

Integer stuId = Integer.parseInt(tmpStr.substring(0,firstIndex));

String stuName = tmpStr.substring(firstIndex + 1,secondIndex);

Integer stuYW = Integer.parseInt(tmpStr.substring(secondIndex + 1,thirdIndex));

Integer stuSX = Integer.parseInt(tmpStr.substring(thirdIndex + 1,forthIndex));

Integer stuYY = Integer.parseInt(tmpStr.substring(forthIndex + 1));

Student student = new Student();

student.setStuId(stuId);

student.setStuName(stuName);

student.setStuYW(stuYW);

student.setStuSX(stuSX);

student.setStuYY(stuYY);

students.add(student);

tmpStr.readLine();

}

//創(chuàng)建一個學生實體類 封裝stuId stuName stuYW stuSx stuYY 這5個屬性。。。

//已經幫你把數(shù)據(jù)拆分出來 并以Student 對象的形式放入集合中了 接下來 給分吧 哇咔咔
