Millistes olukordades on soovitatav kasutada try ja catch konstruktsioone erandite töötlemiseks?

It is recommended to use try and catch structures in situations where there is a likelihood of exceptions occurring during program execution, and it is necessary to handle these errors to prevent the application from crashing unexpectedly. For example:

• When working with input/output (files, network), where access errors may occur.
• During data parsing, when the format may be incorrect.
• When working with databases, to handle connection or query errors.

Using try-catch allows:

• Localizing error handling.
• Providing a comprehensible message to the user.
• Performing alternative actions or cleaning up resources.

Example:

try {
    FileInputStream fis = new FileInputStream("file.txt");
    // work with the file
} catch (FileNotFoundException e) {
    System.out.println("File not found: " + e.getMessage());
}
