[amp_mcq option1=”first among the catch blocks” option2=”last among the catch blocks” option3=”globally, at the top of the file” option4=”at the end of all code in the program” correct=”option2″]<\/p>\n

The correct answer is: B. last among the catch blocks<\/strong><\/p>\n

A default exception block is a block of code that is executed when an exception is thrown and no other catch block matches the exception. It is always placed last among the catch blocks.<\/p>\n

Option A is incorrect because a default exception block can only be placed last among the catch blocks.<\/p>\n

Option C is incorrect because a default exception block is not placed globally, at the top of the file. It is placed last among the catch blocks.<\/p>\n

Option D is incorrect because a default exception block is not placed at the end of all code in the program. It is placed last among the catch blocks.<\/p>\n

Here is an example of a default exception block:<\/p>\n

try {
\n \/\/ code that may throw an exception
\n} catch (IOException e) {
\n \/\/ handle IOException
\n} catch (SQLException e) {
\n \/\/ handle SQLException
\n} catch (Exception e) {
\n \/\/ handle all other exceptions
\n}<\/code><\/p>\n

In this example, the default exception block will be executed if any of the following exceptions are thrown:<\/p>\n
