Why are there sometimes two opening brackets? I understand what the first open bracket does but the second open one confuses me for example....
do{
response = console.readLine( " Do you understand do while loops?"); isInvalid = response.equalsIgnoreCase("No"); if (isInvalid)
{
^ //im alittle consfused with this bracket :0
console.printf(" This is invalid......\n Please try again");
}
}while(isInvalid);

9,483 PointsHi. The first opening curly bracket belongs to the do statement and the second opening curly bracket belongs to the if statement.
do { // Opening bracket of the do statement
response = console.readLine(" Do you understand do while loops?");
isInvalid = response.equalsIgnoreCase("No");
if (isInvalid) { // Opening bracket of the if statement
console.printf(" This is invalid......\n Please try again");
} // Closing bracket of the if statement
} while (isInvalid); // Closing bracket of the do statement
The if statement is inside the do statement. Think of it as Russian nesting dolls. That's why using proper indentation is vital here to read the code easily.
Hope that helps :).
