Give an example of an exception error that you encounter while running your program.
2. How do you solve the exception?
Example of an exception error
An exception is an event, which occurs during the execution of a program, that disrupts the normal flow of the program`s instructions. When an error occurs within a method, the method creates an object and hands it off to the runtime system. The object, called an exception object, contains information about the error, including its type and the state of the program when the error occurred. Creating an exception object and handing it to the runtime system is called throwing an exception. Examples for exceptions are: arithmetic exception, nullpointer exception, divide by zero exception, etc.
he other targets (Kyoto, Kokura, and Nagasaki) were 100 miles away. Flying a B-29 and carrying a 5 ton bomb was already enough work. Hiroshima was finally chosen. Putting a bomb in the middle of Hiroshima would destroy the entirety of the city. Hiroshima was chosen also because of it’s factories and facilities.
After 6:00 a.m, the atomic bomb was fully secured and armed. At 7:00 a.m, the Japanese radar detected one of the three planes that hovered over Hiroshima on the same day as the bombing and informed Hiroshima citizens. The plane had circled around Hiroshima but there were no signs of bombers so citizens quickly dismissed it and started their daily work. By 7:25, Enola Gay was finally cruising over Hiroshima. Enola Gay was 26,000 feet above ground and by 8:00 a.m, the Japanese radar had detected something again. It was the B-29 bomb heading towards Hiroshima. Radio stations were alerted and casted a warning for people to take shelter but many people ignored the warning. The crew at 8:09 had received a message from one of the three planes that weather was nice enough to be dropped.
At 8:14 a.m, the B-29 bomb is dropped over the city of Hiroshima and at 8:15, Little Boy exploded. The atomic bomb exploded 1,900 feet above the center of Hiroshima and immediately kills thousands of people and injuring 100,000 people or more. Crew members of Enola Gay had witnessed seeing a column of smoke rising and intense fire. The temperature of the bomb was estimated to be over a million degrees Celsius which erupted the surrounding air. It formed a fireball 840 feet in diameter. In less than a second, the fireball had expanded to 900 feet. The wave shattered windows 10 miles away and the heat was felt as far away as 37 miles. Eyewitnesses who were more than 5 miles away from the atomic bombing said that the brightness had exceeded the sun 10 times.
