Produce a histogram of the amount of money the gambler ends up with by running this experiment N times. You can throw any type of exception from your code, as long as your method signature declares it.

Class name should start with upper case letter 4. Go ahead and check that. You can not synchronize on the null object but your volatile variable in Java could be null. The author of this FAQ sees no clear advantage to adopting this approach and believes that said developers also put their curly braces on the wrong line.

What does the following do. What is wrong with the following function. Program execution doesn't resume until a catch-block somewhere in the call stack catches the exception. Here is a glimpse of how things appear in our code: Remember to be practical and maximize your testing investment.

Refer to "Where should I put my test files.

Program: Example for static variables and methods.

Such methods modify the content of an object passed in parameter. The Java volatile keyword cannot be used with method or class and it can only be used with a variable. Here is how the callDivide method would look in that case. final is a keyword to declare that method final.
