Try, Catch, Finally in Java

Try-Catch Block

The try statement allows you to define a block of code to be tested for errors. The catch statement allows you to define a block of code to be executed, if an error occurs in the try block.

try {
  int[] myNumbers = {1, 2, 3};
  System.out.println(myNumbers[10]); // Error
} catch (Exception e) {
  System.out.println("Something went wrong.");
}

Finally Block

The finally statement lets you execute code, after try...catch, regardless of the result.

try {
  // code
} catch (Exception e) {
  // handle error
} finally {
  System.out.println("The 'try catch' is finished.");
}
