What is the difference between throws with a method name and an exception catch?

Question

I am very new to exception handling in java, so this question may seem silly, but please let it answer. Suppose I have a method A in which part of the code can throw an exception B , then what is the difference between catching an exception in a method or writing a method declaration as: -

void A() throws B{
     ----//----
     }

Answer 1

The difference lies in the method call.

• throws Exception, , , Exception [ catch], [ throws ].

Answer 9

• : . , - try- , catch, .

• Throwing Exception: . , , , , . , :

method1()   {
x.method2();
  }
  method2() {   
   method3(); 
  }  
method3() throws SomeException   {  .....  ......   }

Then, if the code in method3 throws SomeException, it will be passed to method2, if method2 also does not handle the exception, and then method1, also in the method stack.
