In this section, we will use one try followed by multiple catch blocks. There are different types of exceptions in Java, and for each exception we can add separate catch blocks.

Let's explain this using the previous example. The exception written for the previous code is a general exception, so for any error in the try block, the general exception is executed. Now let's try and catch a specific exception. We can add a catch block under the try block, and add a specific exception and a print statement to print, I caught the Arithmeticerror/exception. The code for the specific catch block is:

catch(arithmeticException et)
{
    System.out.println("I caught the Arithmeticerror/exception");
}

When we run the code, we get the following output:

I caught the Arithmeticerror/exception

We see that, when we ran the code, the controller went to the catch block, because the catch block is specifically written for an arithmetic exception, and the error thrown...
