*How can I print color in console?* **如何在控制台中打印颜色？** *I want to show data in colors when the processor sends data and in different colors when it receives data.* **我想在处理器发送数据时以彩色显示数据，而在接收数据时以不同的颜色显示数据。**

*You could do this using ANSI escape sequences.* **您可以使用ANSI转义序列来执行此操作。** *I've actually put together this class in Java for anyone that would like a simple workaround for this.* **实际上，我已经将Java中的此类放在一起，以供任何想要简单解决方法的人使用。** *It allows for more than just color codes.* **它不仅允许使用颜色代码。**

StringBuilder sb = new StringBuilder(); System.out.println( sb.raw("Hello, ") .underline("John Doe") .resetUnderline() .raw(". ") .raw("This is ") .color16(StringBuilder.Color16.FG_RED, "red") .raw(".") );

*Here are a list of colors in a Java class with `public static` fields* **这是带有`public static`字段的Java类中的颜色列表**

***Usage*** **用法**

System.out.println(ConsoleColors.RED + "RED COLORED" +
    ConsoleColors.RESET + " NORMAL");

***Note** Don't forget to use the `RESET` after printing as the effect will remain if it's not cleared* **注意不要忘记在打印后使用`RESET` ，因为如果不清除，效果会保留**

*If anyone is looking for a quick solution, feel free to use the following helper class :)* **如果有人在寻找快速解决方案，请随时使用以下帮助程序类：）**

public class Log {
    
        public static final String ANSI_RESET = "\u001B[0m";
        public static final String ANSI_BLACK = "\u001B[30m";
        public static final String ANSI_RED = "\u001B[31m";
        public static final String ANSI_GREEN = "\u001B[32m";
        public static final String ANSI_YELLOW = "\u001B[33m";
        public static final String ANSI_BLUE = "\u001B[34m";
        public static final String ANSI_PURPLE = "\u001B[35m";
        public static final String ANSI_CYAN = "\u001B[36m";
        public static final String ANSI_WHITE = "\u001B[37m";
    
        //info
        public static void i(String className, String message) {
            System.out.println(ANSI_GREEN + className + " : " + message + ANSI_RESET);
        }
    
        //error
        public static void e(String className, String message) {
            System.out.println(ANSI_RED + className + " : " + message + ANSI_RESET);
        }
    
        //debug
        public static void d(String className, String message) {
            System.out.println(ANSI_BLUE + className + " : " + message + ANSI_RESET);
        }
    
        //warning
        public static void w(String className, String message) {
            System.out.println(ANSI_YELLOW + className + " : " + message + ANSI_RESET);
        }
    
    }

***USAGE:*** **用法：**

Log.i(TAG,"This is an info message");
    
    Log.e(TAG,"This is an error message");
    
    Log.w(TAG,"This is a warning message");
    
    Log.d(TAG,"This is a debug message");

*If you use Kotlin (which works seamlessly with Java), you can make such an enum:* **如果您使用Kotlin（可与Java无缝集成），则可以进行这样的枚举：**

enum class AnsiColor(private val colorNumber: Byte) {
        BLACK(0), RED(1), GREEN(2), YELLOW(3), BLUE(4), MAGENTA(5), CYAN(6), WHITE(7);
    
        companion object {
            private const val prefix = "\u001B"
            const val RESET = "$prefix[0m"
            private val isCompatible = "win" !in System.getProperty("os.name").toLowerCase()
        }
    
        val regular get() = if (isCompatible) "$prefix[0;3${colorNumber}m" else ""
        val bold get() = if (isCompatible) "$prefix[1;3${colorNumber}m" else ""
        val underline get() = if (isCompatible) "$prefix[4;3${colorNumber}m" else ""
        val background get() = if (isCompatible) "$prefix[4${colorNumber}m" else ""
        val highIntensity get() = if (isCompatible) "$prefix[0;9${colorNumber}m" else ""
        val boldHighIntensity get() = if (isCompatible) "$prefix[1;9${colorNumber}m" else ""
        val backgroundHighIntensity get() = if (isCompatible) "$prefix[0;10${colorNumber}m" else ""
    }

*And then use is as such: (code below showcases the different styles for all colors)* **然后这样使用：（下面的代码展示了所有颜色的不同样式）**

val sampleText = "This is a sample text"
    enumValues<AnsiColor>().forEach { ansiColor ->
        println("${ansiColor.regular}$sampleText${AnsiColor.RESET}")
        println("${ansiColor.bold}$sampleText${AnsiColor.RESET}")
        println("${ansiColor.underline}$sampleText${AnsiColor.RESET}")
        println("${ansiColor.background}$sampleText${AnsiColor.RESET}")
        println("${ansiColor.highIntensity}$sampleText${AnsiColor.RESET}")
        println("${ansiColor.boldHighIntensity}$sampleText${AnsiColor.RESET}")
        println("${ansiColor.backgroundHighIntensity}$sampleText${AnsiColor.RESET}")
    }

*If running on Windows where these ANSI codes are not supported, the `isCompatible` check avoids issues by replacing the codes with empty string.* **如果在不支持这些ANSI代码的Windows上运行，则`isCompatible`检查通过将代码替换为空字符串来避免问题。**
