在Java中,一共有8种基本 类型(primitive type),其中由4种整型、2种浮点类型、1种用于表示Unicode编码的字符单元 的字符类型char和1种用于表示真值的boolean类型。 在Java中,所有的数值类型所占据的字节数量与平台无关。注意,Java没有任何无符号类型(unsigned). 1)整型 整型用于表示没......
In Java, a data type defines the type of data that a variable can hold. It determines the size & layout of the variable's memory, the range of values that can be stored within that memory, & the set of operations that can be performed on the variable. Java is a statically-typed lan...
A variables can be defined as to reserve memory space to store the values. These can be initialized at the time of declaration or later on depending on the type of variable. There are basically three type of variable available in java: local variables, instance variables and static variables....
In Java, objects are created from classes, and variables of reference types hold references to these objects. When a reference type variable is assigned the null literal, it means that it does not currently point to any valid object in memory. 2. Default Value If you declare a reference typ...
Thread is a lightweight process. It is lightweight because they utilize the minimum resources of the system. Thread is an independent concurrent path of execution of a group of statements. Thread takes less memory and less process time.
is a dynamic data structure that is its size is not fixed. Linked list has a head node and a tail node and each available node in a linked list contain a pointer to its adjacent node. It is to be noted that nodes of a linked list are present at non-contiguous locations in memory....
Private Memory Private memory is, as its name says, memory that is specific to the process. Most of the memory you deal with in a program is actually private memory. Since changes made in private memory are not visible to other processes, it is subject to copy-on-write. As a side-effe...
Every implementation of the Java programming language is required to support two standard sets of floating-point values, called the float value set and the double value set. In addition, an implementation of the Java programming language may support either or both of two extended-exponent floating...

Using a union to interpret bits as different types is the quintessence of C. It opens up a number of clever optimizations and lets you slice and dice each byte of memory in ways that memory-safe languages disallow. But it is also wildly unsafe and will happily saw your fingers off if yo...
