Here is a code snippet illustrating exception handling:
try {
int a= 3 / 0 ;
} catch ( ArithmeticException e ) {
System.out.println ("An ArithmeticException has occured");
} finally {
// some code
}
In JAVA, is exception handling implicit or explicit or both. Explain with the help
of example java programs.
We can create a exception sub class by extending Exception class available in java
Exception handling in Java is done through a try-catch-finally block. The "try" block of code is where you put the code which may throw an exception. The "catch" block of code is where you put the code which will execute after an exception is thrown in the try block. This is often used to display an error message, or to mitigate problems caused by the exception. The "finally" block is where you put code that you want to execute after the try and catch blocks have been processed. // example code for catching exception while reading from a file try { // this line of code can throw a FileNotFoundException FileReader in = new FileReader("myfile.txt"); // this line of code can throw an IOException in.read(); } catch(FileNotFoundException ex) { // catch first exception type System.err.println("Cannot find myfile.txt!"); } catch(IOException ex) { //catch second exception type System.err.println("Cannot read from myfile.txt!"); } finally { // no matter what we want to close the file, so do it here // however, this line can also cause an exception, so we need to catch that, too try { in.close(); catch(IOException ex) { // not much we can do about an exception that occurs here } }
Meta data, overall, can hold a huge amount of information about a website. However, the three most important types of meta data are: Meta keywords (the keywords that describe what a page is about) Meta Title (the page's title) Meta Description (a full, but short description of a webpage.)
An exception is literally that: an exception. Exceptions are thrown when something that shouldn't happen does. For example, if you're trying to turn "Hi" into an Integer, you'll get a NumberFormatException (in Java.) If there is nothing in place to handle an exception, the program will crash. Try-catch blocks are used for exception handling within methods, and exception throwing is used to give out exceptions, or let a different method handle it. Example program (Java): class ex{ public static void main(String[] args){ String Strx = "5a"; int x = 0; try{ x += Integer.parseInt(Strx); }catch(NumberFormatException e){ // If Strx is not an Integer x += Integer.parseInt("5"); } System.out.println("The value of x is " + x); // The value of x is 5 } } Alternatively, you could remove the try-catch blocks, and simply write "public static void main(String[] args) throws NumberFormatException" in the 2nd line of the program.
Error occurs at runtime and cannot be recovered, Outofmemory is one such example. Exceptions on the other hand are due conditions which the application encounters, that can be recovered such as FileNotFound exception or IO exceptions
