Recovering from a checked exception in Java
If you are working on the back-end, this might be of use. Very trivial but rarely used.

public class CheckedExceptionRecovery {
/**

public static void main(String... args) {
InputStreamReader inputStreamReader = new InputStreamReader(System.in);
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
int input = 0;
boolean done = false;
do {
try {
System.out.println("Please enter an integer: ");
input = Integer.parseInt(bufferedReader.readLine().trim());
done = true;
} catch (NumberFormatException numberFormatException) {
System.out.println("Invalid input. Please try again.");
} catch (IOException ioException) {
System.out.println("Cannot proceed.");
}
} while (!done);
System.out.println("The integer is: " + input);
}
}
