http://javajee.com/introduction-to-exceptions-in-javaJava exception mechanism provides a way to handle runtime errors, making Java programs more reliable, robust, and fault-tolerant. Here are the advantages of Java exception mechanism:
A. Improves the program structure because the error handling code is separated from the normal program function: The Java exception mechanism separates the error handling code from the normal program function, improving the program's overall structure. This separation makes the program easier to read, write, and maintain because it isolates the error-handling logic in one place. This allows the code to be more focused and less cluttered, leading to better program organization and improved readability.
B. Provides a set of standard exceptions that covers all the possible errors: Java provides a comprehensive set of standard exceptions that cover all possible errors that can occur during program execution. This makes it easy for programmers to handle common errors without having to write custom exception classes for every possible scenario. This reduces the amount of code required, making the program more concise and easier to read.
C. Improves the program structure because the programmer can choose where to handle exceptions: Java's exception mechanism allows programmers to choose where to handle exceptions, providing more control over the program's execution flow. This means that exceptions can be caught and handled at different levels of the program hierarchy, depending on the nature of the error and the program's requirements. This flexibility improves the program's structure and makes it more robust.
D. Improves the program structure because exceptions must be handled in the method in which they occurred: Java requires exceptions to be handled in the method in which they occurred, ensuring that the error is dealt with immediately and preventing it from causing further issues downstream. This improves the program's structure by promoting a more modular design, where each method is responsible for its own error handling.
E. Allows the creation of new exceptions that are tailored to the particular program being created: Java's exception mechanism allows programmers to create custom exceptions that are tailored to the particular program being created. This enables the program to handle specific errors in a more meaningful way, improving the program's reliability and making it more user-friendly.
In summary, the Java exception mechanism provides several advantages, including improved program structure, comprehensive error coverage, flexible error handling, modular design, and the ability to create custom exceptions.
