java - Syntax error on token ";" ... why? -

-

why there syntax error on line ( shown below ) ? thanks

import java.util.stringtokenizer;  public class tokenizer  {               public tokenizer()    {    }             int n;    string esempio = "ciao dodo sos";    stringtokenizer tok = new stringtokenizer(esempio); // <---- syntax error on token ";"     while (tok.hasmoreelements())       system.out.println("" + ++n +": "+tok.nextelement()); }

the compiler attempting associate stringtokenizer declaration while loop expecting opening brace { (for anonymous implementation block) rather semi-colon ;.

you need use method rather have code in class block:

int n = 0; string esempio = "ciao dodo sos"; stringtokenizer tok = new stringtokenizer(esempio);   void dosomething() {     while (tok.hasmoreelements()) {       system.out.println("" + ++n +": "+tok.nextelement());    } }

a while statement non-declarative statement must appear in method, static initializer or constructor.

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
