Exceptions in Java

In this post, you will learn how to work with exceptions so that you can use that same knowledge and thus evolve.

• an exception is an event that occurs during the execution of a piece of code that interrupts its normal flow of instructions;
• in short, an exception represents an error;
• the try executes the entire piece of code present in itself and automatically passes to the catch;
• the catch checks the result of what was executed inside the try and transmits what is contained in it (most of the time the exception itself);
• the finally is executed whether there is any exception or not.

package com.caffeinealgorithm.programminginjava;

public class Exceptions {
  public void Run() {
    int[] numbers = new int[] {
        1, 2, 3, 4, 5
    };

    try {
      System.out.printf("Element content: %d\n", numbers[4]);
    } catch (Exception exception) {
      // System.out.println("The code in the try is not working correctly.");
      System.out.println(exception);
    }
    finally {
      System.out.println("I am part of the finally and I'm executed if there is any exception or not.");
    }
  }
}
