Exception in thread "main" java.lang.ArithmeticException: Trying to divide by 0 at Main.divideByZero(Main.java:5) at Main.main(Main.java:9) In the above example, we are explicitly throwing theArithmeticExceptionusing thethrowkeyword. Similarly, thethrowskeyword is used to declare the type of...
When defining your own exception type, study the existing exception classes in the Java API and try to extend a related exception class. For example, if you’re creating a new class to represent when a method attempts a division by zero, you might extend classArithmeticExceptionbecause division...
public class ExceptionExample { public static void main(String[] args) { try { int result = divide(10, 0); // 这里会抛出ArithmeticException System.out.println("Result: " + result); } catch (ArithmeticException e) { System.err.println("Error: " + e.getMessage()); } finally { ...
In some cases, special characters in input may be valid. So, we do special processing for that, using NumberFormat, for example, which supports numerous formats. 4. Conclusion In this tutorial, we discussed NumberFormatException in Java and what causes it. Understanding this exception can help ...
