100% yes but it is not a suggested practice.
The purpose of a catch block in java code is to handle exceptions. If you want to throw exceptions, then there is no point in writing the try-catch block. We could throw the exception at the point where it occurs instead of writing the try - catch block to catch it and throw it again.

Can you throw exception from catch block in net?

Define a catch block?
A Catch block is part of the exception handling mechanism in Java. It is used along with the try block. Ex: try { ... } catch (Exception e) { ... } The catch block is used to catch & handle the exception that gets thrown in the try block.
Explain about exception handling with multiple exception?
Exception handling in Java is done through a try-catch-finally block. The "try" block of code is where you put the code which may throw an exception. The "catch" block of code is where you put the code which will execute after an exception is thrown in the try block. This is often used to display an error message, or to mitigate problems caused by the exception. The "finally" block is where you put code that you want to execute after the try and catch blocks have been processed. // example code for catching exception while reading from a file try { // this line of code can throw a FileNotFoundException FileReader in = new FileReader("myfile.txt"); // this line of code can throw an IOException in.read(); } catch(FileNotFoundException ex) { // catch first exception type System.err.println("Cannot find myfile.txt!"); } catch(IOException ex) { //catch second exception type System.err.println("Cannot read from myfile.txt!"); } finally { // no matter what we want to close the file, so do it here // however, this line can also cause an exception, so we need to catch that, too try { in.close(); catch(IOException ex) { // not much we can do about an exception that occurs here } }
What is the use of catch block in java?

Why use throw in java in compare try-catch?

How many catch blocks can you use with one try block with example?
A try block can have multiple catch blocks, each handling a different type of exception. Be careful about the order of laying the exceptions. Using Exception at the top will catch everything that is derived from it, thereby missing the other specfic exception catches. And there can also be only one finally block.
What is meant by throw command in c plus plus?
A 'throw' statement throws an exception when it is generated within a try block. The exception is then caught by the corresponding catch block. For example, void somefn() { float m, n; try { cin>>m>>n; if (n == 0) throw(n); else cout<<(m/n); } catch (float x) { cout<<"Division by zero not possible"; } }
If a method calls another method and that method throw an exception then caller method must be throw that exception or not?
If method A calls method B and method B throws an exception, then method A must handle that exception. It does not have to throw the exception if it is in a try-catch block, but it must do something to deal with it.Note that this only applies to checked exceptions. If method B throws an unchecked exception, then A is allowed to ignore it.
How do you use try block in cpp?
A try statement is used in conjunction with one or more catch blocks to provide exception handling. If an exception is thrown by a try block, the corresponding catch block will handle the exception. If no catch block is provided for a particular exception, then a runtime error occurs instead. Try-catch statements are used to provide graceful resolutions to potential runtime errors.
What happens when raised exception is not caught by catch block?
A non-caught exception is propagated out of the local catch block into the next catch block, daisy chaining to the outermost catch block in the run-time library, where it will be handled by abending the program.
Why use catch keyword in java?
no, because catch is used to handle exceptions which are generated from try block
