What are all the checked exceptions in Java?

I'd be happy to help you with that!

In Java, a checked exception is an exception that must be either caught and handled or declared to be thrown in the method's throws clause. There are several types of checked exceptions, but here's a comprehensive list:

These checked exceptions must either be handled within the method where they are declared (by using try-catch blocks) or declared to be thrown by a parent class using the throws keyword. This is why checked exceptions are often referred to as "compile-time" exceptions because they require explicit handling at compile time.

Hope this helps you with your Java endeavors!

What is throw and throws in Java?

I'll respond in English this time!

In Java, "throw" is a keyword that is used to intentionally terminate the execution of a method or block of code, throwing an exception to its caller. An exception is an object that represents an error or unusual condition that has occurred during the execution of a program.

When you throw an exception, you're essentially saying, "Hey, something went wrong here, and I'm not going to continue executing this code." The exception will propagate up the call stack until it's either caught by a try-catch block or reaches the top-level method, at which point it will terminate the program.

On the other hand, "throws" is a keyword that appears in a method signature and indicates that the method may throw an exception. It's used to declare the types of exceptions that a method might throw when invoked.

Here's an example:

public void myMethod() throws MyException {
// code that might throw an exception
}
public void anotherMethod() {
try {
myMethod();
} catch (MyException e) {
// handle the exception
}
}

In this example, myMethod() is declared to throw a MyException. When you call myMethod() from within anotherMethod(), it might actually throw that exception. The try-catch block in anotherMethod() will catch the exception and take some action to handle it.

So, to summarize:

Understanding when to use "throw" and "throws" is crucial in Java programming, as it allows you to effectively handle errors and unusual conditions in your code.
