Reconstruction background and causes
Recently, due to the continuous expansion of the project team, the Code style in the project varies, and the project may be full of flowers or even anger. Taking into account the survival and development of the

Question 2 Comparison Between String equals and "=", stringequals
"="Compare whether the object is the same, that is, whether the memory address is the same
"Equals in String"Content of the comparison object
"Equals in Object"If the equals method is
Java String equals and =, javastringequals
Public class Test_String {Public static void main (String [] args ){String a = new String ("aa ");String B = new String ("aa ");System. out. println (a = new String ("aa"); // false = creates an object
Let's take a look at the Code:
The output result of this Code is:
Ture
True
--------------
False
It seems that the object class is special. Let's take a look at the source code of the equals () method under the object.
The queals ()
Recently, I wrote a recursive method. During the comparison and determination, the integer type is integer, And the integer type is created when it is greater than 127 or less than-128, this is because of the integer-type disassembly box

Comparison between the equals method of String in java and "=", stringequals
Package stringTest; public class StringDemo {public static void main (String [] args) {// The strings defined in the following two methods are different String s1 = new
Differences between equals and = in Java
= Compare the addresses of two objects, while equals compares the content of two objects.
Obviously, when equals is true, ==is not necessarily set to true;
The importance of basic knowledge is expected to
Scenario 1String s = "Test ";String t = string. Copy (s );Console. WriteLine (s = t );Console. WriteLine (object) s = (object) t );The output is true and false.
Case 2String s = "Test ";String t = s;Console. WriteLine (s = t );Console. WriteLine
There are multiple methods to compare strings with C #, such:
1. string. Compare (x, y );2. string. Equals (x, y );
If it is case-insensitive, the result is:String. Compare (x, y );String. Equals (x, y );
Note: The meaning of the comparison result

In this era of WEB APIs, the WEB Service technology seems outdated. outdated technologies do not mean that they are useless, and they can still be used in some places, the reason
The definition of string in. NET 2.0 is as follows:
