Throws is a Java keyword that is used to handle exceptions. It is an important part of error handling in Java and is used to specify that a method may throw an exception of a particular type.
Using Throws in Methods
When a method declares that it throws an exception, it means that the method may encounter a particular type of exception during its execution. If an exception is thrown, it will be propagated to the calling method. The calling method can then handle the exception or re-throw it.
The syntax for declaring that a method throws an exception is:
java
public void myMethod() throws ExceptionType {
// Method body
}
In this example, the method myMethod() declares that it may throw an exception of type ExceptionType.
Benefits of Using Throws
There are several benefits to using throws:
It helps in identifying the potential exceptions that a method may encounter.
It allows the caller to handle the exception appropriately or re-throw it for further handling.
It promotes clean and well-organized code, as it separates error handling from the main logic of the method.
