Before understand the concept of Catch u have to understand
the concept of try,that is why try?

Try-------it is used when we know that some piece of code is
going to throw some exception example when u are dividing
somthing/0 means it may throw exception so we use the try
block and put that code inside the try block

Catch:--------Every try there must be catch or finally
block. Catch is used to catch to exception.As for example
the division example may throw airthmatic exception so will
declare this exception in catch like

Catch(AirthmaticException ae)
{
System.out.println("hi cannt divide by zero");
System.out.println(ae);
}
