java中数据插入数据库的新手问题～

Question

大概代码如下：
.
.
.
.
String name=jTextField1.getText();
String age=jTextField2.getText();
 
/**********************如何达到如下的效果*****************************/String InserInfo=("insert into student(Sname,Sage) values (name,age)");/*********************************************************************/int ins=sql.executeUpdate(InsertInfo);
.
.
.

Answer 1

String InserInfo=("insert into student(Sname,Sage) values ('"+name+"','"+age+"')");

Answer 2

--因为name、age是变量，所以要连接到串中。String InserInfo=("insert into student(Sname,Sage) values ('" + name + "'," +age + ")");

Answer 3

多谢大家了，下面是我自己写的～～  吐血了
StringBuffer st= new StringBuffer();
             st.append("insert into ");
             st.append(TableSort);
             st.append("(Address,Area,ZhuangXiu,Environment,Floor,Equipment,BuiltYear,Price,FangXing,FaceTo,Structure,PhoneNum,Re,Name,Peitao)");
             st.append(" values(");
             st.append("'");
             st.append(jTextField1.getText());
             st.append("',");
             st.append("'");
             st.append(jTextField2.getText());
             st.append("',");
             st.append("'");
             st.append(jComboBox1.getSelectedItem().toString());
             st.append("',");
             st.append("'");
             st.append(jTextField4.getText());
             st.append("',");
             st.append("'");
             st.append(jComboBox4.getSelectedItem().toString());
             st.append("',");
             st.append("'");
             st.append(jTextField7.getText());
             st.append("',");
             st.append("'");
             st.append(jTextField14.getText());
             st.append("',");
             st.append("'");
             st.append(jTextField5.getText());
             st.append("',");
             st.append("'");
             st.append(jComboBox5.getSelectedItem().toString());
             st.append("',");
             st.append("'");
             st.append(jComboBox2.getSelectedItem().toString());
             st.append("',");
             st.append("'");
             st.append(jComboBox3.getSelectedItem().toString());
             st.append("',");
             st.append("'");
             st.append(jTextField12.getText());
             st.append("',");
             st.append("'");
             st.append(jTextField16.getText());
             st.append("',");
             st.append("'");
             st.append(jTextField15.getText());
             st.append("',");
             st.append("'");
             st.append(jTextField13.getText());
             st.append("'");             
             st.append(")");
