Error handling mechanisms like exceptions cause deviations in the usual control flow of the program. These deviations make it harder to reason about the program and are often the source of bugs in the program. Java provides exception handling via the Try-Catch-Finally statement. A ~weimer/p/...
In the above program, we have created a static class namedUSBinside the classMotherBoard. Notice the line, MotherBoard.USB usb =newMotherBoard.USB(); Here, we are creating an object ofUSBusing the name of the outer class. Now, let's see what would happen if you try to access the me...

When a try catch block is present in another try block then it is called the nested try catch block. Each time a try block does not have a catch handler for a particular exception, then the catch blocks of parent try block are inspected for that exceptio
In the above program, we create an empty dictionary3inside the dictionarypeople. Then, we add thekey:valuepair i.epeople[3]['Name'] = 'Luna'inside the dictionary3. Similarly, we do this for keyage,sexandmarriedone by one. When we print thepeople[3], we getkey:valuepairs of dictiona...
