Question

JAVA What is the technical definition of a crash? (Remember, only normal people call it a crash. Now that you are programmers, you know to call it something else and why.)

Answer 1

Crash happens, when program stops unexpectedly. i.e. When some instruction fails to execute and cause the program to stop working or behave in some different way like it hangs.

In programming language, this is called Exception.

An exception happens when program execution disrupts from its normal flow and executes unexpected behavior. We need to handle these exceptions using Exception handling technique.

For eg. If program tries to divide a number by 0, it crashes, we need to catch that exception and prevent program from crashing.

eg.

try {

int b = 0;

int c = 10;

int a = c/b;

} catch (ArithmeticException e) {

System.out.println("Divide by zero exception occured");

}
