how to use try catch in programs? 0

 
Enslose the code ( code which might throw exception) you want to monitor inside the "try" block.
for example- 1/0 ; this throws the Division by zero exception(ArithmeticException)
so put 1/0 in "try" block

void tryDemo() {
try {
int x = 5/0;
} catch(ArithmeticExcption e) {
system.out.println("Exception is " + e);
}

in "catch" clause we specified what type of exception we want to catch and what we want to do after that exception is caught.

We can handle the exception like the following,

we can handle all the exception in the exception class, because exception is the super class of all the exception whether it is subclass of runtime class or subclass of exception class.


try{
int a=10;
int b=0;

int c=a/b;
}
catch(Exception e)
{
Sop("Exception occurred");
}		0
