"Digital System Converter" framework in the Java class library: entry guide

"Digital System Converter" framework in the Java class library: entry guide Digital system conversion is a process of converting numbers between different progress.In software development, the digital system converter is often used to convert numbers from one in -order to another, such as converting decimal numbers into binary, octagonal or hexadecimal.The Java class library provides a convenient and powerful "digital system converter" framework, making these conversion simple and efficient.This article will introduce how to get started and use the "digital system converter" framework in the Java class library, and provide some example code. Step 1: Introduce dependencies First of all, in your Java project, you need to introduce the dependence of the "digital system converter" framework in the Java class library.You can use Maven or Gradle to build tools, and add the following dependencies to your project configuration file. Maven: <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-lang3</artifactId> <version>3.11</version> </dependency> Gradle: implementation 'org.apache.commons:commons-lang3:3.11' Step 2: Create a converter object Next, you need to create a converter object to execute the digital system conversion.The "Digital System Converter" framework in the Java class library provides a `Numbersystem` class to implement this function.We can complete this step by creating an object of a `NUMBERSYSYSYSYSTEM` and passing into the transformation as a parameter. import org.apache.commons.lang3.math.NumberSystem; Numbersystem converter = New Numbersystem (16); // Create a hexadecimal converter Step 3: Execute conversion Once you create a converter object, you can use it to execute the conversion of the digital system.The Java class library provides many useful methods to achieve mutual conversion between different progress. For example, we can use the `TobinaryString` method to convert a decimal number to binary: String binary = converter.tobinaryString (42); // Convert decimal number 42 to binary System.out.println (binary); // The output result is: 101010 Similarly, we can use the `TOOCTALSTRING" method to convert a decimal number to an octagonal: String octal = converter.toOCTRING (42); // Convert decimal number 42 to octagonal System.out.println (Octal); // The output result is: 52 Similarly, we can use the `tohexstring` method to convert a decimal number to hexadecimal: String hexadecimal = converter.tohexstring (42); // Convert decimal number 42 to hexadecimal System.out.println (hexadecimal); // The output result is: 2a Step 4: Other conversion operations In addition to the conversion operation in the above examples, the "digital system converter" in the Java class library also provides many other operations, such as converting the numbers representing the string to other advances, converting the number of the character array to other numbers to other.In advance, converting other advanced numbers into decimal, and so on. For example, we can use the `Tolong` method to convert a binary number represented by a string to decimal: long decimal = converter.tolong ("101010", 2); // Convert the string "101010" to decimal System.out.println (decimal); // The output result is: 42 Step 5: Note When using the "digital system converter" framework in the Java class library, you need to pay attention to the following: -Senging that the transformation of the provided is within the effective range.The advancement must be between 2 and 36 and must be matched with the digital system used, otherwise the conversion will fail. -It processed input errors, such as when the number input is invalid or cannot be converted. -The can customize the converter object as needed to achieve specific conversion needs. Summarize: This article introduces how to use the "digital system converter" framework in the Java library to implement the conversion between digital systems.By introducing dependencies, creating converters and performing conversion operations, we can easily convert numbers between different progress.I hope this article will help you understand and use the "digital system converter" framework in the Java class library. The following is a summary of some common methods of the "Digital System Converter" framework in the Java library used in the example code: import org.apache.commons.lang3.math.NumberSystem; public class NumberSystemConverterExample { public static void main(String[] args) { Numbersystem converter = New Numbersystem (16); // Create a hexadecimal converter String binary = converter.tobinaryString (42); // Convert decimal number 42 to binary System.out.println (binary); // The output result is: 101010 String octal = converter.toOCTRING (42); // Convert decimal number 42 to octagonal System.out.println (Octal); // The output result is: 52 String hexadecimal = converter.tohexstring (42); // Convert decimal number 42 to hexadecimal System.out.println (hexadecimal); // The output result is: 2a long decimal = converter.tolong ("101010", 2); // Convert the string "101010" to decimal System.out.println (decimal); // The output result is: 42 } }
