Here's a Hello World application:
import static java.lang.System.out;
class HelloWorld
{
public static void main(string[] arguments)
{
out.println("Hello world!") //this will print out the words 'Hello world!' to the screen
} //End of main method
} //End of class HelloWorld
The most common reason I have for catching Exceptions in Java is when reading information from a file. So let's look at an example where we read and display the contents of a file.
// Note that the main method may throw a FileNotFoundException.
// This means that if the file we try to read from doesn't exist, the program will
// exit with an Exception.
public static final void main(final String[] args) throws FileNotFoundException {
// Create a new FileReader object which reads from myfile.txt
// This is the line which may throw the FileNotFoundException
Reader in = new FileReader("myfile.txt");
// Begin the try block, which will catch any IOExceptions
try {
// Read and display the file contents
int ch;
while ((ch = in.read()) != -1) {
System.out.print((char) ch);
}
// Close the input object
in.close();
} catch (IOException ex) {
}
// And we're done.
System.out.println("End Of File Reached");
}
