15,203 PointsThere is a way in which do-while loop works(similar for while loop).
There are 2 things to note:
1:> DO{ do some tasks; }WHILE (till this condition satisfies);
2:> Every sentence in java ends with a semi-colon(;)
Now lets see the code:
//Lets create a variable called response
String response ;
//Now lets ask for response and if response in "No", we continue asking;
do {
//asking for response from user
response = console.readLine("do you understand do while loops? ");
} while (response.equals("No"));
//after while is a semi-colon
Hope this helps.

15,203 PointsAlso, it is worth noting that first "do" block runs and then check for condition. If condition satisfies then it run again otherwise it stops.
So unlike "for" and "while" loop, "do-while" always runs at least once.
