while(response.equalsIgnoreCase("No")); String newResponse = console.readLine("Do you undestand do while loops?");

while(response.equalsIgnoreCase("No")); String newResponse = console.readLine("Do you undestand do while loops?");

where am i going wrong?

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.
String response = console.readLine("Do you understand do while loops?");
do{
  if(response.equalsIgnoreCase("No")){
    console.printf("Keep running the loop");
  }
}while(response.equalsIgnoreCase("No"));
String newResponse = console.readLine("Do you undestand do while loops?");

You need to continually prompt the user in the loop so you can keep on acquiring new input:

String response = console.readLine("Do you understand do while loops?");
do{
  response = console.readLine("Do you understand do while loops?");
  // The condition in the while takes care of the termination logic
  // no if statement is required for this.
} while(response.equalsIgnoreCase("No"));
