How a CT system works. 1  A motorized table moves the patient (Figure 3) through a circular opening in the CT imaging system. 2  As the patient passes through the CT imaging system, a source of x rays rotates around the inside of the circular opening. A single rotation takes about 1 second.
Static blocks are mainly used for initialization of static variables of class which you can't do with the help of constructors. Here are some rules which governs functioning of static blocks:-. 1) They are called when a class is loaded into the JVM. 2) They are executed in the order which they appear in the class. 3) They are executed only once. 4) They are used as class level members only - which means you CANNOT put them inside any methods.
Can static method be overridden in Java, or can you override and overload static method in Java, is a common Java interview question, mostly asked to 2 years experienced Java programmers. Answer is, No, you can not override static method in Java, though you can declare method with same signature in sub class. It won't be overridden in exact sense, instead that is called method hiding. But at same time, you can overload static methods in Java, there is nothing wrong declaring static methods with same name, but different arguments.
