Explanation of Solution

Explanation:

The “try”-with-resources statement ensures that a resource is closed when the statement ends normally or abruptly.

To use this statement, the programmer needs to declare the needed resources within the parenthesis, and the built resource will be closed automatically at the end of the block.

When closing resources, the programmer must use “try”-with-resources instructions.

Consider the following sequence of statements:

//Create an instance variable

PrintWriter pout = new PrintWriter(file_name);

//Call the method

writeData(pout);

//Call close() method

pout...

Explanation of Solution

Type of exception being caught:

An exception is a problem that comes during the program execution.

An exception caught by a surrounding “catch” clause depends on the exception type being caught by the “catch” clause...

Explanation of Solution

A sample program:

When the programmer uses a resource, which should be closed, like a “PrintWriter”, the programmer requires to be careful in the presence of exceptions.

Consider the following sequence of statements:

//Create an instance variable

PrintWriter pout = new PrintWriter(file_name);

//Call the method

writeData(pout);

//Call close() method

pout.close();

Let’s assume that one of the methods prior to the last line throws an exception.

Then the invocation to the method “close()” is never executed.

The data that was written to the stream may never end up in the file.

Therefore, the programmer uses the try-with-resources statement...
