He chatted with Brother Z just now and asked:
In Java, are you referring to or passing values?At that time, I mixed up the meaning of this "pass" and thought it was an Object Instantiation, for example:Abc a = new ABC ();Is a reference type or value type, so:Most of them are passed by reference (Reference Type), There are several common types: Value Transfer (Original TypeFor example, Int.==========================================The answer is comple
Today, the archive relationship is to transfer the archive from zhongzhi company to FESCO in Zhongguancun. It is actually a very simple task, but I still haven't completed the whole day, really depressing. on this day, I started from the West second flag chengtie, went to Zhongguancun twice, went to Guanghua Road twice (International trade), and finally ran to the ground. I am exhausted by subway addiction. why? I first went to zhongzhi to get the arc

Java data type and parameter transfer, java data type transfer
Java provides two types of data: Basic Data Type and reference data type.
Basic Data Types in Java
Name
Size
Value Range
Byte type (in bytes)

Short Type (short integer)
16bit
-2 ^ 15 to 2 ^ 15-1
Int type (integer)
32bit
-2 ^ 31 to 2 ^ 31-1

Many books have mentioned that only value passing exists in Java, but today we see this in the source code of a NanoHTTPD:
1 if (qmi >= 0) {2 decodeParms(uri.substring(qmi + 1), parms);3 uri = decodePercent(uri.substring(0, qmi));4 }
1 /** 2 * Decodes parameters in percent-encoded URI-format ( e.g. 3 * "name=Jack%20Danielspass=Single%20Malt" ) and adds them to given 4 * Map. NOTE: this doesn't support multiple identical keys due to the 5 * simplicity of

The specific steps are as follows.3) in this article, we use [unconditional call transfer] as an example, and then click activate ], enter the number to be transferred and click OK.Friendly reminder, of course, some people
When calling a custom function, it is often encountered to pass arguments to the called function, and the parameters are passed by value and by reference.
Transfer by value (Pass-by-value mechanism): When transferring variables to a function, the variable value is not passed directly to the function, but a copy of the variable value is first made and stored on the stack, which is used to invoke the function instead of the variable itself. This method
. Summary
In the Java parameter pass, it is divided into value passing and reference passing. (Many people say that the following is an object transfer, but Java, everything is object, or say that the reference is better), the following first to a summary: If the transfer of the basic data type values, the modification of the formal parameters will not affect the argument. If you pass a non-basic data type

In fact, the principle of resumable upload is very simple, that is, the HTTP request is different from the general download. For example, when a browser requests a file on the server, the request is as follows:
