Question

My program will provide information on buildings, which is stored in an online Oracle database. I got it to ask the user to enter the building number and then run and display the results of several queries.

Here is what I got so far:

String userbnumber = null;
try {
    BufferedReader obj = new BufferedReader(new InputStreamReader(System.in));
    System.out.print("Please enter the building number: "); 
    userbnumber = obj.readLine();
} catch (IOException e) {   
}
// A Lot of queries which use userbnumber as the basis for getting data from tables

However, what I can’t figure out is how /where to use the do-while clause to keep asking for the building number until the user enters 0 at which point the program would print “Thank you for your time” and stop.

Any help would be greatly appreciated.

Answer 1

 BufferedReader obj = new BufferedReader(new InputStreamReader(System.in));
 do {
     try {
         System.out.print("Please enter the building number: "); 
         userbnumber = obj.readLine();
         if(!usernumber.equals("0"){
         //perform action here
         }
     } catch (IOException e) { 
         //handle it
     }
 } while(!userbnumber.equals("0"));  

better way is to

while(true){
        try {
             System.out.print("Please enter the building number: "); 
             userbnumber = obj.readLine();
             if(usernumber.equals("0"){
                     break;
             }
             //perform action here
         } catch (IOException e) { 
             //handle it
         }

}
