Java Language Tutorial => Exceptions and exception handling

Introduction

Objects of type Throwable and its subtypes can be sent up the stack with the throw keyword and caught with try…catch statements.

void someMethod() throws SomeException { } //method declaration, forces method callers to catch if SomeException is a checked exception type

try {

someMethod(); //code that might throw an exception

}

catch (SomeException e) {

 System.out.println("SomeException was thrown!"); //code that will run if certain exception (SomeException) is thrown

}

finally {

 //code that will always run, whether try block finishes or not

}
