Transferred from: http://www.cnblogs.com/zhxhdean/archive/2011/03/25/1995431.htmlThe data types in Java can be divided into two categories:1. Basic Data Types  also known as primitive data types, Byte,short,char,int,long,float,double,boolean,

1. First, string does not belong to eight basic data types. String is an object. Because the default value of an object is null, the default value of string is also null, but it is a special object and has some features that other objects do not

When the angel used Oracle, he found that the use of single and double quotation marks was different. Then he checked some information online and made some summary: Double quotation marks: when an object is created, the object name and field name

Problem introduction: Question 1: String str1 = "ABC ";String str2 = "ABC ";System. Out. println (str1 = str2); // true Question 2: String str1 = new string ("ABC ");String str2 = new string ("ABC ");System. Out. println (str1 = str2); //

1. Definition and initialization of character ArraysThe easiest way to initialize a character array is to assign characters to each element in the array one by one.Char str [10] = {'I', '', 'A', 'M','', 'h', 'A', 'P ', 'P', 'y '};Assign 10

In the Java language. The string plays a very critical data. There are two cases where the declaration and initialization of a string are as follows:(1) for a string S1=new string ("ABC") statement with a string s2=new string ("ABC") statement,

C and Pointers ("pointers on C") 8.1.11A string, such as "Hello", is usually a string constant that can be used to assign a value to a character pointer, or to initialize it, equivalent to assigning the first address of the string constant to the

string constants. It is called a constant, because it can be regarded as an unnamed string and is a constant, stored in the static data area.The static data area is relative to the dynamic data area such as heap and stack.The static data area holds
