LESSON 17: EXCEPTION HANDLING IN JAVA
๐ Exception handling is one of the most important feature of java programming that allows us to handle the runtime errors caused by exceptions.
โ๏ธAn 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:
1๏ธโฃ Checked Exception
2๏ธโฃ Unchecked Exception
