web application: poor error handling source code review

Today I received a report from the security team. The report contains the vulnerabilities and description mentioned below:

1) Mishandling errors: Excessively wide shots

The methods in program1.java throw a generic exception that makes it difficult for callers to do a good job of handling and error recovery.

2) Bad error handling: too wide capture

The catch block in EXAMPLE 1.java line 146 handles a wide range of exceptions, potentially catching different problems or problems that should not be addressed at this point in the program.

3) Defective error handling: empty capture block

The SomeMethod () method in somefile.java ignores an exception on line 33, which could cause the program to ignore unexpected states and conditions.
