// I have initialized a java.io.Console for you. It is in a variable named console.
String response ;
boolean task;
do {
  response = console.readLine ("Do you understand do while loops?  /n");
  task = (response.equalsIgnoreCase ("No");
 if (task)
          { console.printf("try again" );

You are missing a closing parenthesis ) where task is being assigned. You could just delete the left one. And I see a lone curly brace } with no left side partner also, three lines down from there. Additionally, I don't believe that the string value of "no" will be taken as a boolean, which is what task is to be assigned. With task declared to be boolean, task needs to take 0 or 1, True or False, not a string. You could declare it to be a string, but then any value it contains will be counted as True when it's evaluated in the if(). You should expand the if() condition to check for the value of "no" like this if( task == "no") and you'll need to change the declaration of task to be string instead of boolean.

You don't need any if() condition, the do{} while() is enough. Just do the line for console.readLine() while (response == "no" || response == "No") make sure to reassign the value of response each time the loop runs. You don't need a task variable nor the if().
