spring - combining methods with same flow in controller. -


method 1. 

@requestmapping(value="/getprofessor") public @responsebody list<object> getmember(httpservletrequest request){    httpsession session = request.getsession();    hashmap user = (hashmap)session.getattribute("user_info");     map<string, object> param = new hashmap<string, object>();    param.put("phone", (string)user.get("phone");     reportmanager  manager = new reportmanager();     list<object> list = manager.getprofessor(param); }

method 2.

@requestmapping(value="/getmember") public @responsebody list<object> getmember(httpservletrequest request){    httpsession session = request.getsession();    hashmap user = (hashmap)session.getattribute("user_info");     map<string, object> param = new hashmap<string, object>();    param.put("phone", (string)user.get("phone");     reportmanager  manager = new reportmanager();     list<object> list = manager.getmember(param); }

the code above briefly describe how list of members , professors. 2 methods have same code flow except url , bottom-most methods. know, 1 of core principles in oop 'combine repeating problems'. so, point want combine these method 1 method. 

public map<string, object> getparams(httpservletrequest request){     httpsession session = request.getsession();     hashmap user = (hashmap)session.getattribute("user_info");      map<string, object> param = new hashmap<string, object>();     param.put("phone", (string)user.get("phone"); }  @requestmapping(value="/getprofessor") public @responsebody list<object> getmember(httpservletrequest request){      reportmanager  manager = new reportmanager();      list<object> list = manager.getprofessor(this.getparams(request)); }  @requestmapping(value="/getprofessor") public @responsebody list<object> getmember(httpservletrequest request){      reportmanager  manager = new reportmanager();      list<object> list = manager.getprofessor(this.getparams(request)); }

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 <...
