First let's look at a few concepts:Stack: An area allocated by the JVM to hold actions and data references that are executed by the thread. Heap: An area allocated by the JVM for storing data such as objects. Constant pool constant pool: a chunk of storage allocated in the heap for storing explicit string,float or integers. This is a special shared area that can be shared in memory without changing things that can be put here. Get to the point: String a = "abc"; ①String b = "abc"; ② uses string

Quote from this friend: http://blog.sina.com.cn/s/blog_6a6b14100100zn6r.htmlYou know, in Java, in addition to the basic types in 8, the others are class objects and their references. So "xyz" is a string object in Java. For a string class object, his object value cannot be modified, that is, invariant.See:String s= "Hello";S= "Java";String s1= "Hello";String S2=new string ("Hello");Ah, is the string object referenced by s not modified? What did you sa

Let's first look at a simple program. Public class t {private string STR = "########### java2000 ################### ##"; public void test () {string S = "@ java2000 @@@@@@@@@@@@@"; string Ss = "########### java2000 #####################"; // same as STR specially }} Let's take a look at what this class actually generates. Let's open T. Class The two strings we used already exist. Note that there are two strings, and the repeated strings do not appear twice. Conclusion: This type of st

This is a very interesting and in-depth topic in the ghost broadcaster dotnetw.baodian ().pdf ).pdf. String S = new string ("XYZ"); how many string instances are created? The teacher told the students that the answer is two: one is "XYZ" and the other is a reference object pointing to "XYZ. It seems to be correct. It makes sense. Yes, "

The php regular expression cannot end with a single string abc or xyz. If it is a single string, it cannot end with a string abc: ([^ abc] $ I? Evaluate the php regular expression.

earth's elliptical sphere. As shown in, if the coordinate of point P is expressed by XYZ, It is the Cartesian coordinate of the central earth, and if it is expressed by bLH, it is the central earth coordinate. The central earth Cartesian coordinate system is generally used to describe a large number of satellite locations, such as the location of the SPOT5 satellite. For Spot5 remote sensing images, the dim file contains items describing the satelli

In Java, except for the basic type in 8, other objects are class objects and their references. Therefore, "XYZ" is a string object in Java. For a String object, its object value cannot be modified, that is, it is immutable. See:String S = "hello ";S = "Java ";String S1 = "hello ";String S2 = new string ("hello "); Ah, isn't the string object referenced by S Modified? Where did I go for immutability? Don't worry. Let me tell you what happened:Dur
