Hello, my friends. In this video, we will learn the Try-Catch Block. So, what is the try-catch block in Java?

If we want to handle the exception ourselves, we can use a try-catch block. In Java, the try block is used to enclose the code that may throw an exception. A try block consists of a set of executable statements. During the execution of these statements, exceptions can be thrown. A method that may throw an exception can also be enclosed by the try block. A try block is always followed by a catch block. We handle the exception in the catch block. One or more catch blocks can follow a try block. In the catch block, we use the exception object to print details of the exception. As you can see in the diagram, first the try block is executed. If the code in the try block throws an exception, the catch block is executed.

Let's take a look at how multiple catch blocks are used now. We use multiple catch blocks after the try block. A try block may be followed by any number of catch blocks. Each catch block handles a particular type of exception. Before Java 7, we used to catch multiple exceptions one by one as shown in the slide. With Java 7, if a catch block handles multiple exceptions, we can separate them using a pipe. And in this case, the exception parameter is final, so we can't change it. This feature reduces code redundancy. Yes, that's what the try-catch block in Java is like. Let's take a short break here. In the next video, we will talk about the finally block. So, I'll see you then friends.
