Throws or try-catch

Question

What is the general rule of thumb when deciding whether to add a throws clause to a method or using a try-catch?

From what I\'ve read mysel

Answer 1

When to use what. I searched a lot about this. There is no hard and fast rule.

"But As a developer, Checked exceptions must be included in a throws clause of the method. This is necessary for the compiler to know which exceptions to check. By convention, unchecked exceptions should not be included in a throws clause.
Including them is considered to be poor programming practice. The compiler treats them as comments, and does no checking on them."
