Java Exceptions and Catch Clause

Question

Aryan Kumar · Answer

A try-catch block is a block of code that can be used to handle exceptions. If an exception is thrown in a try-catch block, the exception will be caught by the catch block and the code in the catch block will be executed.
The syntax for a try-catch block is as follows:
try {
  // Code that could potentially throw an exception
} catch (Exception e) {
  // Code that handles the exception
}
The try block contains the code that could potentially throw an exception. The
catch block is used to handle the exception. The Exception keyword is a placeholder for the type of exception that can be caught.
Here is an example of a try-catch block:
try {
  int x = 10;
  int y = 0;
  int z = x / y;
} catch (ArithmeticException e) {
  System.out.println("Division by zero");
}
In this example, the try block contains the code that could potentially throw an exception. The code that could throw an exception is the
int z = x / y; statement. If the y variable is equal to 0, then the
ArithmeticException exception will be thrown.
The catch block is used to handle the ArithmeticException exception. The
catch block will be executed if the ArithmeticException exception is thrown. The
catch block will then print the message "Division by zero".
If the y variable is not equal to 0, then the ArithmeticException exception will not be thrown. In this case, the
try block will execute normally and the catch block will not be executed.
