This code fragment implements an error handler using try/catch to handle a potential NumberFormatException when parsing a double from user input. The catch block prints an error message if the parsing throws a NumberFormatException. Finally, it prints "Done" after the try/catch. The missing keyword in the catch block is catch.

1. Consider the following code fragment. This code contains a partial implementation of an error
handle-select the keyword that goes in the ?????? space? Double value; try{system.out.print
("Please enter a number:"); string line = scan, next(); value = Double.parseDouble (line);//may
throw exception} ?????? (Number format Exception e) {system.out.printe In ("error. Please
enter a valid number.");} finally {system.out.print In ("Done.");} break catch else except
Solution
30. Consider the following code fragment.
* This code contains a partial implementation of an error handler-select the keyword that goes in
the ?????? space ?
double value ;
try
{
System.out.println("lease enter a number : ") ;
String line = scan.next();
value = Double.parseDouble(line); // may throw exception
}
??? (NumberFormatException e)
{
System.out.println("Error.Please enter a valid number.") ;
}
finally
{
System.out.println("Done.") ;
}
Answer :-

2. The given code contains a partial implementation of an error handler - the keyword that goes in
the ?????? space is catch .
