LESSON 17: EXCEPTION HANDLING IN JAVA 🖇 Exception handling is one of the most important feature of java programming that allows us to handle the runtime errors caused by exceptions. ✂️An Exception is an unwanted event that interrupts the normal flow of the program. Java try and catch The try statement allows you to define a block of code to be tested for errors while it is being executed. The catch statement allows you to define a block of code to be executed, if an error occurs in the try block. public class Main { public static void main(String[ ] args) { try { int[] myNumbers = {1, 2, 3}; System.out.println(myNumbers[10]);//this num is not found in the array } catch (Exception e) { System.out.println("Something went wrong."); } } } THERE ARE 2 PRIMARY EXCEPTION TYPES: 1️⃣ Checked Exception 2️⃣ Unchecked Exception Contact_bot » https://t.me/LearnToCode_bot

LESSON 16: Java Operator Precedence > Operator precedence determines the order in which the operators in an expression are evaluated. > the operator with the highest precedence is operated first. > the multiplication is performed before subtraction > Example: Operator precedence class Precedence { public static void main(String[] args) { int a = 10, b = 5, c = 1, result; result = a-++c-++b; System.out.println(result); } } ‼️What will be the output of the above example❓
