Well-off study with you JAVA -------- data type conversion, java type conversion
This article describes a common output situation in JAVA: data type conversion.
The data type of Java has been determined at the time of definition, so it cannot be converted to other data types at will, but Java allows users to perform type con
The factors that determine the maintainability of the software are:1) comprehensible 2) testability 3) modifiable 4) Portability 5) reusabilityWhat measures should be taken:1) Improved accessibility: Modular • Detailed design documentation • Structured design • Documentation within the program and good high-level programming language2) Improved testability: Good documentation is essential for diagnostics and testing, and
As an industry, application software development has been developing for more than 30 years. However, it may be complicated or invisible to software, but it is still in the original production mode of manual workshop, development relies on a large amount of manpower, making it difficult to ensure the quality and high cost of use and O M.
There are many reasons for this situation, but I think the most fun
Original address: C + + conversion constructors and implicit conversion functionsThe transformation constructor allows you to convert data of a specified type into an object of a class. However, you cannot turn an object of a class into another type of data, such as converting a complex class object to a double type of data.C + + provides type conversion function
float. Otherwise, it is treated as an integer.
This value is determined by the first part of the string. If a string starts with a valid number, use this number as its value. Otherwise, its value is 0 (0 ). Valid numeric data starts with an optional plus or minus sign, followed by one or more numbers (including decimal scores), followed by an optional index. An index is an "e" or "E" followed by one or more numbers.
Do not expect to get the encoding of a character when converting it into an in

As soon as I opened my blog today, I saw the 5-year-old campus in the upper left corner, and my eyes were a bit blank. The scenes of my previous class as a student have gradually become blurred. Yes. I have been graduating for more than three years, so I will not be here again...

On one occasion, I turned on the TV to look around and accidentally caught a war movie. Thousands of communist fighters set up ladders to break a fortress. But the enemy on the tower was putting up a desperate battle to intercept our attack. Both casualties are very heavy, but the city is unable to attack. Seeing that the rest of us are not many, suddenly I do not know from where to open a tank, two guns will be opened the gate. Our troops took advantage of the city and wiped out all the enemies

This is my first note. I will update the content from time to time, and I hope you can correct it and make common progress!
I. Basic Data Types
There are four basic data types:
1> int data types: byte (8 bits), short (16 btis), int (32 bits), long (64 bits );
2> float length data types

1. Export conversion component
Export column conversion reads data from the data stream and inserts the data into the specified file. the secondary conversion uses paired data columns: one column is the data to be output, and the other column is the files to which the data is output. during conversion, data is inserted

ExampleThe order of the ADC1 rule channels is CH0,CH1,CH2,CH3,Do not start scan mode:In one-time conversion mode:Start ADC1, then1. Start converting CH1 (First channel of ADC_SQR)Stop when the conversion is complete, wait for the ADC to start the next time, and continue to convert from the first stepIn Continuous conversion mode:Start ADC1, then1. Start convertin
In the previous article, we introduced four situations of C ++ implicit conversion. I believe you should have a detailed understanding of this data type conversion method. Here, we will introduce the basic content of the explicit C ++ conversion method in detail.

RTTI and type conversion, RTTI type conversionRTTIThrough runtime type recognition (RTTI), the program can use pointers or references of the base class to retrieve these pointers or reference the actual derived types of objects. The following two operators provide the RTTI: 1. typeid operator to return the actual type of the pointer or referenced object. 2. The dynamic_cast operator securely converts a pointer or reference of the base class type to a
One, automatic type conversionIn Java programs, it is often necessary to convert data between different basic data types. For example:,the int variable score1 in the code can perform the assignment directly for the double type variable score2, and The result is: 82.0This conversion is called automatic type conversion . Of course, automatic type conversions are required to meet specific conditions : The targ
