Error handling is an important feature in any programming language. A good error handling mechanism makes it easier for programmers to write robust applications and to prevent bugs from creeping in. In some languages, programmers are forced to use multiple if statements to detect all possible conditions that might lead to an error. This could make code excessively complex. In a larger program, this could easily lead to spaghetti like code.
Java offers the try statement as a nice approach to error handling. With this strategy, part of the code that could potentially lead to an error is isolated in a block. Should an error occur, this error is caught and resolved locally. This chapter teaches you this.
