Java offers three ways to catch multiple exceptions: using multiple catch blocks for different exception types, the multi-catch feature to handle multiple exceptions in a single block, and a catch-all block for general exception handling. Let’s look in depth at each. Use multiple catch blocks ...
In Java SE 7 and later, we can now catch more than one type of exception in a singlecatchblock. Each exception type that can be handled by thecatchblock is separated using a vertical bar or pipe|. Its syntax is: try{// code}catch(ExceptionType1 | Exceptiontype2 ex) {// catch bloc...
Handling More Than One Type of Exception In Java SE 7 and later, a singlecatchblock can handle more than one type of exception. This feature can reduce code duplication and lessen the temptation to catch an overly broad exception. Consider the following example, which contains duplicate code in...
2. Handling Exceptions Exception handling is the mechanism to deal with exceptions in our Scala application. The most common approaches to deal with exceptions are either by using the Java-style try–catch or the most idiomatic one in Scala, the Try type: scala> import scala.util.{Failure, ...
Java rethrow exception Another improvement is done in Compiler analysis of rethrown exceptions. Java rethrow exception allows you to specify more specific exception types in the throws clause of a method declaration. Let’s see this with a small example: ...

In java, when we handle more than one exceptions within a single try {} block then we can use multiple catch blocks to handle many different kind of exceptions that may be generated while running the program. However every catch block can handle only one type of exception. This mechanism is...
TheonException()function is based onrecoverCatching(). Therefore,only if the result’sisFailureistrue, our exception handling is performed. Moreover,thetransform()function defines what we want to do if certain exceptions are thrown. So next, let’s createsave4()using the declaredonException()fu...
