difference between throw and throws in java
| throw is used to explicitly throw an exception. Wherever you want that exception occurs you can use throw. throws is used with method signature. If in a method there occurs an exception you can provide throws with method signature which gives the user idea that there may occur an exception in this method. |  0 |

| 1.Throws clause in used to declare an exception and thorw keyword is used to throw an exception explicitly. 2. If we see syntax wise than throw is followed by an instance variable and throws is followed by exception class names. 3. The keyword throw is used inside method body to invoke an exception and throws clause is used in method declaration (signature). 4.throws keyword cannot be used anywhere exception method signature while throw keyword can be used inside method. | 0 |

| Thanks for all your replies.We can handle the exception or simply throw the exception by using throws. What my question is how to decide we have to use throw or throws? this is the question asked in one of my interview. | 0 |

| You use throws in a method signature to indicate that a method is capable of throwing a particular exception. Any code calling this method will have to deal with the possibility that that particular exception can occur. The throw keyword is used to actually throw an exception. It can be used wherever you can place a statement. | 0 |
