mysql - java sql update query syntax error -


i want update data , delete , replace table single time. don't know how this.

com.mysql.jdbc.exceptions.jdbc4.mysqlsyntaxerrorexception: have error in sql syntax; check manual corresponds mysql server version right syntax use near'(cash,change)values('9000','your change is:40.0')where room='9' , name' @ line 1

 try{     chge=jtextfield27.gettext();     cash=jtextfield4.gettext();      string sqll = "update customer (cash,chnge) values ('" + cash + "','" + chge + "') room = ? , name = ?;";          dbase5 = conn.preparestatement (sqll);      dbase5.setstring(1,jtextfield1.gettext());     dbase5.setstring(2,jtextfield2.gettext());     int b = dbase5.executeupdate();      ////////move history        string sql = "insert history select * customer room = ? , name = ?";              dbase = conn.preparestatement (sql);         dbase.setstring(1,jtextfield1.gettext());         dbase.setstring(2,jtextfield2.gettext());         int rs=dbase.executeupdate();         ///////move history     string msql = "delete customer room=? , name=?";         dbase1 = conn.preparestatement (msql);          dbase1.setstring(1,jtextfield1.gettext());         dbase1.setstring(2,jtextfield2.gettext());         boolean s = dbase1.execute();         this.dispose();

all of above queries right except update query:

    update customer (cash,chnge) values ('" + cash + "','" + chge + "') room = ? , name = ?;

it should below:

    update customer set cash = '" + cash + "', chnge = '" + chge + "' room = ? , name = ?;

or may set first 2 arguments preparedstatement:

    update customer set cash = ?, chnge = ? room = ? , name = ?;

i recommend go through below link: http://dev.mysql.com/doc/refman/5.7/en/update.html

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
