1. Clean Up Resources in a Finally Block or Use a Try-With-Resource Statement

2. Prefer Specific Exceptions

3. Document the Exceptions You Specify

4. Throw Exceptions With Descriptive Messages

5. Catch the Most Specific Exception First

6. Don’t Catch Throwable

7. Don’t Ignore Exceptions

8. Don’t Log and Throw

9. Wrap the Exception Without Consuming It

public class Main {

    public static void main(String[] args) {
	// write your code here
	    System.out.println("First line");
	    System.out.println("Second line");
	    System.out.println("Third line");

	    try {
	        int[] myIntArray = new int[]{1, 2, 3};
	        print4thItemInArray(myIntArray);
	    } catch (ArrayIndexOutOfBoundsException e){
	        System.out.println("The array doesn't have four items!");
	    }

	    System.out.println("Fourth line");
	    System.out.println("Fith line");
    }

    private static void print4thItemInArray(int[] arr) {
        System.out.println(arr[3]);
    }
}
