string constant

Excerpt from http://www.cnblogs.com/SaraMoring/p/5687466.htmlJava memory allocations mainly include the following areas:1. Register: We have no control in the program2. Stack: A reference to the basic type of data and objects, but the object itself

1. Definition and initialization of character arrayThe easiest way to understand the initialization of a character array is to assigned each element in the array by word.Char str[10]={' I ', ' ', ' a ', ' m ', ' ', ' h ', ' A ', ' P ', ' P ', ' Y '};

1. The character pointer can point to a string. We can initialize the character pointer with a string constant. For example, there is a description statement:Char " This is a string. ";is to initialize the character pointer. At this point, the

About string comparisons with equals or = =, summarize.The string is an object: 1. " = = "All" object variables are compared by = = Two objects are referenced in the heap. 2. " Equals () "The Equals method of all objects inherits from the method of

For string objects in Java, individuals think that every programmer will think, learn, and study this object, because he is the interviewer's favorite. For example: string s = new String ("abc"), and several objects were created. This problem

The process of compiling a program for C + + compiles is preprocessing, compiling, and linking. A preprocessor is a program that processes source files based on pre-processing instructions before the program source files are compiled. Preprocessor

To speak of stacks, heaps, method areas, and constant pools in Java, mention Hotspot,hotspot is the virtual machine that is in the sun jdk and Open JDK. (The code implementation is essentially the same except for the annotations of the Sun JDK and

Numeric Constants A numeric constant is what is commonly called a constant. In C + +, numeric constants are type-sensitive, and their types are recognized in literal form. Type of integer constant (integer)As you know in the previous section:

Data | data type 1. First, string does not belong to 8 basic data types, and string is an object. Because the default value of the object is NULL, the default value of string is also null, but it is a special object with some attributes that other
