}if(type.equals("教师")){ sql="Select*fromteacherwherenum=" +name+"andpwd="+pwd; }try{rs=db.Query(sql);while(rs.next()){name1=rs.getString("name");num=rs.getString("num");if(type.equals("教师")){classes=rs.getString("classes"); } } }catch(SQLExceptione1){ e1.printStackTrace(); }if(!name1.equals("")){if(type.equals("学生")){ Login.this.close();try{ Displaydisplay=Display.getDefault(); studentshell=newstudent(display); shell.open(); shell.layout();while(!shell.isDisposed()){if(!display.readAndDispatch()){ display.sleep(); } } }catch(Exceptione1){ e1.printStackTrace(); } }if(type.equals("教师")){ Login.this.close();try{ Displaydisplay=Display.getDefault(); AddChengshell=newAddCheng(display); shell.open(); shell.layout();while(!shell.isDisposed()){if(!display.readAndDispatch()){ display.sleep(); } } }catch(Exceptione1){ e1.printStackTrace(); } } }else{ MessageDialog.openError(getShell(),"提示","用户名密码错误"); } }else{ MessageDialog.openWarning(getShell(),"提示","你还没选择登录类型"); } }else{ MessageDialog.openWarning(getShell(),"提示","密码不能为空"); } }else{ MessageDialog.openWarning(getShell(),"提示","用户名为空"); } 修改密码功能修改在此登录的用户，修改密码的用户必须输入原密码，和新密码才能进展密码的修改。如图4-6修改密码4-6修改密码代码如下：Stringsql="updateteachersetpwd='"+text_1.getText()+"'wherenum='"+Login.num+"'";booleanb=MessageDialog.openQuestion(getShell(),"提示","是否修改密码");if(b){db.Update(sql); MessageDialog.openWarning(getShell(),"提示","修改密码成功"); } 注册用户功能点击进入注册用户的功能后，进展相应的提示进展操作，填入对应的教师的信息后点击添加就可以成功的注册一个新的用户了，在进展相关的操作，如图4-7注册图4-7注册新用户代码如下：if(!text.getText().equals("")){if(!text_1.getText().equals("")){if(!text_2.getText().equals("")){if(!text_3.getText().equals("")){ Stringsql="insertintoteachervalues('"+text.getText()+"','"+text_2.getText()+"','"+text_1.getText()+"','"+text_3.getText()+"')";booleanb=MessageDialog.openQuestion(getShell(),"提示","是否注册");if(b){db.Update(sql); MessageDialog.openWarning(getShell(),"提示","注册成功"); } } } } }4.2.2教师端登录类型选择教师，进入教师端，此处含有增加，删除，修改和教师修还密码等功能，每一步都有相应的校验。选择功能进展操作。增加学生成绩功能进入之后会有提示，输入学号，成绩，学年等信息，点击确定完成添加学生成绩的操作。如图4-8教师端图4-8教师端代码如下：if(!num.equals("")){if(!fenshu.equals("")){if(!xueqi.equals("")){ Stringsql="insertinto分数values('"+kemu+"','"+fenshu+"','"+num+"','"+xueqi+"')";db.Update(sql); num=""; fenshu=""; fenye(); MessageDialog.openWarning(getShell(),"提示","添加成功"); }else{ MessageDialog.openError(getShell(),"提示","学期不能为空"); } }else{ MessageDialog.openError(getShell(),"提示","分数不能为空"); } }else{ MessageDialog.openError(getShell(),"提示","学号不能为空"); }选择某个人后点击鼠标右键，会出现修改和删除功能。如图4-9鼠标右键功能图4-9鼠标右键功能 修改学生成绩选择某个人之后，右键选择修改功能，就会出现如图4-10的界面，修改学号和成绩后点击确定，即可修改学生成绩图4-10修改学生成绩代码如下：Stringsql="updateteachersetpwd='"+text_1.getText()+"'wherenum='"+Login.num+"'";booleanb=MessageDialog.openQuestion(getShell(),"提示","是否修改密码");if(b){db.Update(sql); MessageDialog.openWarning(getShell(),"提示","修改密码成功"); } 删除学生成绩右键选择删除学生成绩功能，会出现如图4-11的询问框，选择确认，删除此学生的成绩，点击否即为取消删除图4-11删除学生信息代码如下：Stringsql="deletefrom成绩wherenum='"+text_1.getText()booleantag=MessageDialog.openQuestion(getShell(),"提示","是否删");if(tag){db.Update(sql); MessageDialog.openWarning(getShell(),"提示","删除成功"); }4.2.3学生端学生端查询学生信息的功能，该功能含有按学年查询，按科目和查询全部等功能，选择功能进展操作，如图4-12图4-12学生查询代码如下：Stringsql="Select*fromstudentwherenum='"+name+"'andpwd='"+pwd+"'";rs=db.Query(sql);try{while(rs.next()){ TableItemtableItem=newTableItem(table,SWT.NONE); tableItem.setText(0,""+rs.getString("1")); tableItem.setText(1,""+rs.getString("2")); tableItem.setText(2,""+rs.getString("3")); tableItem.setText(3,""+rs.getString("4")); tableItem.setText(4,""+rs.getString("5"));tableItem.setText(4,""+rs.getString("6")); } }catch(SQLExceptione){ e.printStackTrace(); }五、设计总结通过几天的课程设计使我懂得了理论与实际相结合是很重要的，只有理论知识是远远不够的，只有把所学的理论知识与实践相结合起来，从理论中得出结论，才能真正为社会服务，从而提高自己的实际动手能力和独立思考的能力。在设计的过程中遇到问题，可以说得是困难重重，这毕竟第一次真真的做程序设计，难免会遇到过各种各样的问题，同时在设计的过程中发现了自己的缺乏之处，对一些前面学过的知识理解得不够深刻，掌握得不够结实，比方说构造体，通过这次课程设计之后，我们把前面所学过的知识又重新温故了一遍。六、程序清单packageStudent;importjava.sql.ResultSet;publicclassAddChengextendsShell{privateTexttext_1;privateTexttext_2;privateTabletable;privateTexttext;publicintstart=0;publicintpage=1;publicintrow_number=0;publicintmaxPage=0;publicintpageSize=5;
