**Checked Exceptions

Exceptions which are to be checked or handled or should be taken care during the time of writing the code are called as checked exceptions. For eg: 1. we have FileNotFoundException -->which will be occured when we are writing some code related to file classes. There will e defenetly posibility of non existence of file. In such case in order to handle them , we are forced to handle those exception for sure. 2. one more example is ParseException ,which will be occured when we are dealing with date functions.

UnChecked Exceptions

These are the exceptions that are optional to be handled during the time of coding. Its up to us whether we handle them or not. In case if we fail to handle them, There is a chance of getting runtime errors during the exceution. For eg: We have something called NullPointerException,ArithemeticException,NosSuchElementFoundException and so on. These are like optional things we dont even have to handle them. More over even jvm or compiler will not recommend us to handle them.**
