Let’s explore an example below where we can check if an operation succeeded or failed via a Boolean check and with the use of an enum type declaration: class Result { success: boolean; // in our code we can set this to either true or false // also we must have seen constructs ...
boolean flag = false; String result = String.format("%b", flag); Output: false In this code snippet, we declare a boolean variable flag with a value of false. The String.format("%b", flag) method converts the boolean to its string representation. The %b format specifier is used ...
