Java 7 introduced the multi-catch feature, allowing you to handle multiple exception types in a single catch block. This can lead to more concise and readable code, especially when you want to handle different exceptions in the same way. Here's a simple example: try{// code that may throw...
So far we have seen how to use a single catch block, now we will see how to use more than one catch blocks in a single try block. 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...
If a catch block handles multiple exceptions, you can separate them using a pipe (|) and in this case, exception parameter (ex) is final, so you can’t change it. The byte code generated by this feature is smaller and reduce code redundancy. Java rethrow exception Another improvement is ...

// Java code try { // ... } catch (Exception1 | Excpetion2 ex) { // Perform some common operations with ex } However,Kotlin hasn’t supported this feature until the current version (1.7.0).So, in this tutorial, we’ll explore how to implement the “multi-catch” feature in Kotli...
The optionaldefaultcase acts as a catch-all, executing its code block if none of the specified cases match the value of the variable. Output: Weekday Use the Arrow Syntax to Use Multiple Values for Oneswitch-caseStatement Java 14 introduces a new syntax for theswitch-casestatement. Users can...
catch (IOException ex) { logger.log(ex); throw ex; } catch (SQLException ex) { logger.log(ex); throw ex; } In releases prior to Java SE 7, it is difficult to create a common method to eliminate the duplicated code because the variableexhas different types. ...
