passed by value, obj accesses the same object by reference. Therefore, when you add the Name property to obj inside a function, the person outside the function will also react because the object pointed to by person has only one and global object in the heap memory. Many developers mistakenly think that the objects modified in the local scope are reflected in the global scope, stating that the parameters are passed by reference, but see the following example,Example C:function SetName () {Obj.n

Preface: Continue the C Series. 1. Variable name Variable name Nothing to say, simply filtered. 2. Data type and length Handwriting trouble, a direct screenshot. Let's take a look at an example: Write a program to determine the char, short, int, long types that are qualified by signed and unsigned respectively The range of variables to be evaluated. Implemented using the corresponding values in the print standard header file. Directly give the pri

one, the conversion between the basic data type and its corresponding encapsulation class basic data types are converted to encapsulated classes 1 • Direct Assignment (automatic packaging) Integer i=3; 2 • Using the enclosing parameter constructor of the encapsulated class (instantiated) Integer i=new integer (3); 3 • Use the valueof () method provided by the encapsulation class (static method) Integer i=integer.valueof (3); encapsulate class to bas

Java offers two different types: reference types and primitive types (or built-in types). For example: int is the raw data type of Java, and integer is the wrapper class provided by Java for Int. Java provides encapsulation classes for each primitive type, and the common primitive and corresponding encapsulation classe

Among them is the Java programming Tutorial is a Chinese-American work, and Nicholas C.zakes's "JavaScript advanced Programming", there is this illustrator C # 2008, translated into "illustration c#2008", There are actually not many illustrations. This is my first time to read the original book completely, feeling good and deep. One is my English incredibly still can, want to test six grade still worse than 20 points, –!! Second, the Foreigner writes the book really is attentively writes, treats

Java Study Notes (3) data types, java Data Types Data Type: The data type determines the storage space occupied by the data in the memory and the storage method. Each data type has its value range. The Compiler allocates memory space for each variable or constant data type. Java data types can be classified into two types
