1。`==`and `！=`operator

Net

Net has the same value of the comparison value of the ==overload 字符串等于.

Java

Java is 串slick, and due to its nature, the referrer is the same, the same, the same and the same is impossible.
Developers 字符串等于use it for developers .

2。 + operator

Net:

串s=“asd”+b+“qwe”; //>>串s=串。康卡特（“asd”，b，“ qwe”）;

串。cs
。NETconcat Principle

[System。安全。安全性安全关键]  //自动生成上市 静态的 串 Concat（串 str0， 串 str1） {// 合同는Test및유효성사검스를스클래스임。合同。确保（合同.结果<串>（) ！= 空值）;合同.确保（合同.结果</string><string>（).长度 ==（str0 == 空值 ？ 0 : str0.长度) +（str1 == 空值 ？ 0 : str1.长度））；Contract.EndContractBlock（）;如果 （IsNullOr空的（str0）） {如果 （IsNullOrEmpty（str1）） {返回 串.Empty;}返回 str1;}如果 （IsNullOrEmpty（str1）） {返回 str0;}整型 str0长度 = str0.长度;//.NET네이티브를가다가포인터에이를자리자리자串 结果 = FastAllocateString(str0Length + str1.Length）;//그리고다가순서대로삽입FillStringChecked(结果， 0，str0）;FillStringChecked(结果, str0Length, str1）;//그리하여포인터。返回 结果;}

Java:

String s = "asd" + b + "qwe";
//>> String s = new StringBuffer().append("asd").append(b).append("qwe").toString（）;

StringBuffer.java
Java has a StringBufferdifference in principle that it has a string increment operator promise .
