I work for Dental Care Alliance and have connected with many of the hygiene directors for other dental management companies. Sandra Johnson, RDH, director of dental hygiene support for Smile Brands Inc., shared some insights into what characteristics she looks for in a prospective candidate. Sandra knows that hygienists working in the corporate environment need to be great communicators, compassionate, enthusiastic learners, and team players.
Java Collections - Stack. The java.util.Stack class deserves a little explanation on its own. In the text on the List interface the Stack class is listed as an implementation. The typical use of a Stack is not as a List though. A Stack is a data structure where you add elements to the top of the stack, and also remove elements from the top again. This is also referred to as the Last In First Out (LIFO) principle. In contrast, a Queue uses a First In First Out (FIFO) principle.
JVM Tuning: Heapsize, Stacksize and Garbage Collection Fundamental. Heap Size: When a Java program starts, Java Virtual Machine gets some memory from Operating System. Java Virtual Machine or JVM uses this memory for all its need and part of this memory is call java heap memory. Whenever we create object using new operator or by any another means object is allocated memory from Heap and When object dies or garbage collected, memory goes back to Heap space in Java.
