- When we want to throw an exception explicitly, then we should use throw keyword.
- We can throw either checked or unchecked exception in java by throw keyword. The throw keyword is mainly used to throw customized exception(exception defined by the user).
- The general form to declare throw an exception is : throw new exception class name;
- For example, throw new NullPointerException("Demo");
Let's see an example;
static void validate(int income)
throw new ArithmeticException("not able to get loan");
System.out.println("eligible for getting loan");
public static void main(String args)
Exception in thread "main" java.lang.ArithmeticException: not able to get loan
