why we need to throws exception when we can handle it by using try and catch... by using throw...

//A void method
public void sample()
{
 //Statements
//if (somethingWrong) then
IOException e = new IOException();
throw e;
//More Statements
}

by using try and catch

MyClass obj =  new MyClass();
try{
  obj.sample();
} catch(IOException ioe)
{
  //Your error Message here
  System.out.println(ioe);
}

they work exactly same. what are the major differece between them.. plzz explain in POINTS....

They don't work exactly same. Take a look at a tutorial on Exception Handling in java. – Ali Seyedi Apr 10 '16 at 08:22

You don't always know what to do with the Exception, as logging it should be your last resort. In this case you should `throws` it until you know what to do with the exception. – Peter Lawrey Apr 10 '16 at 08:50
