Java不“处理代码”，这是真的，但是Java输出你让它输出的东西。Windows控制台将ESC (chr(27))视为另一个符号(←)，这不是Java的错。

尝试以下枚举:

enum Color {
    //Color end string, color reset
    RESET("\033[0m"),

    // Regular Colors. Normal color, no bold, background color etc.
    BLACK("\033[0;30m"),    // BLACK
    RED("\033[0;31m"),      // RED
    GREEN("\033[0;32m"),    // GREEN
    YELLOW("\033[0;33m"),   // YELLOW
    BLUE("\033[0;34m"),     // BLUE
    MAGENTA("\033[0;35m"),  // MAGENTA
    CYAN("\033[0;36m"),     // CYAN
    WHITE("\033[0;37m"),    // WHITE

    // Bold
    BLACK_BOLD("\033[1;30m"),   // BLACK
    RED_BOLD("\033[1;31m"),     // RED
    GREEN_BOLD("\033[1;32m"),   // GREEN
    YELLOW_BOLD("\033[1;33m"),  // YELLOW
    BLUE_BOLD("\033[1;34m"),    // BLUE
    MAGENTA_BOLD("\033[1;35m"), // MAGENTA
    CYAN_BOLD("\033[1;36m"),    // CYAN
    WHITE_BOLD("\033[1;37m"),   // WHITE

    // Underline
    BLACK_UNDERLINED("\033[4;30m"),     // BLACK
    RED_UNDERLINED("\033[4;31m"),       // RED
    GREEN_UNDERLINED("\033[4;32m"),     // GREEN
    YELLOW_UNDERLINED("\033[4;33m"),    // YELLOW
    BLUE_UNDERLINED("\033[4;34m"),      // BLUE
    MAGENTA_UNDERLINED("\033[4;35m"),   // MAGENTA
    CYAN_UNDERLINED("\033[4;36m"),      // CYAN
    WHITE_UNDERLINED("\033[4;37m"),     // WHITE

    // Background
    BLACK_BACKGROUND("\033[40m"),   // BLACK
    RED_BACKGROUND("\033[41m"),     // RED
    GREEN_BACKGROUND("\033[42m"),   // GREEN
    YELLOW_BACKGROUND("\033[43m"),  // YELLOW
    BLUE_BACKGROUND("\033[44m"),    // BLUE
    MAGENTA_BACKGROUND("\033[45m"), // MAGENTA
    CYAN_BACKGROUND("\033[46m"),    // CYAN
    WHITE_BACKGROUND("\033[47m"),   // WHITE

    // High Intensity
    BLACK_BRIGHT("\033[0;90m"),     // BLACK
    RED_BRIGHT("\033[0;91m"),       // RED
    GREEN_BRIGHT("\033[0;92m"),     // GREEN
    YELLOW_BRIGHT("\033[0;93m"),    // YELLOW
    BLUE_BRIGHT("\033[0;94m"),      // BLUE
    MAGENTA_BRIGHT("\033[0;95m"),   // MAGENTA
    CYAN_BRIGHT("\033[0;96m"),      // CYAN
    WHITE_BRIGHT("\033[0;97m"),     // WHITE

    // Bold High Intensity
    BLACK_BOLD_BRIGHT("\033[1;90m"),    // BLACK
    RED_BOLD_BRIGHT("\033[1;91m"),      // RED
    GREEN_BOLD_BRIGHT("\033[1;92m"),    // GREEN
    YELLOW_BOLD_BRIGHT("\033[1;93m"),   // YELLOW
    BLUE_BOLD_BRIGHT("\033[1;94m"),     // BLUE
    MAGENTA_BOLD_BRIGHT("\033[1;95m"),  // MAGENTA
    CYAN_BOLD_BRIGHT("\033[1;96m"),     // CYAN
    WHITE_BOLD_BRIGHT("\033[1;97m"),    // WHITE

    // High Intensity backgrounds
    BLACK_BACKGROUND_BRIGHT("\033[0;100m"),     // BLACK
    RED_BACKGROUND_BRIGHT("\033[0;101m"),       // RED
    GREEN_BACKGROUND_BRIGHT("\033[0;102m"),     // GREEN
    YELLOW_BACKGROUND_BRIGHT("\033[0;103m"),    // YELLOW
    BLUE_BACKGROUND_BRIGHT("\033[0;104m"),      // BLUE
    MAGENTA_BACKGROUND_BRIGHT("\033[0;105m"),   // MAGENTA
    CYAN_BACKGROUND_BRIGHT("\033[0;106m"),      // CYAN
    WHITE_BACKGROUND_BRIGHT("\033[0;107m");     // WHITE

    private final String code;

    Color(String code) {
        this.code = code;
    }

    @Override
    public String toString() {
        return code;
    }
}

现在我们来举个小例子:

class RunApp {
    public static void main(String[] args) {

        System.out.print(Color.BLACK_BOLD);
        System.out.println("Black_Bold");
        System.out.print(Color.RESET);

        System.out.print(Color.YELLOW);
        System.out.print(Color.BLUE_BACKGROUND);
        System.out.println("YELLOW & BLUE");
        System.out.print(Color.RESET);

        System.out.print(Color.YELLOW);
        System.out.println("YELLOW");
        System.out.print(Color.RESET);
    }
}

您可以使用ANSI转义序列来实现这一点。实际上，我已经在Java中为任何想要简单解决这个问题的人组合了这个类。它允许的不仅仅是颜色代码。

https://gist.github.com/nathan-fiscaletti/9dc252d30b51df7d710a

特性

完整的源代码文档 4位颜色支持(16种颜色) 8位颜色支持(255种颜色) 24位颜色支持(1670万种颜色) 支持十六进制和8位RGB值 支持通用格式 隐藏文本，反转颜色，闪烁，下划线，删除，暗淡，粗体，斜体 能够从包含ANSI转义序列的字符串中剥离ANSI。

示例使用

System.out.println(

   new AnsiStringBuilder()
       // All formatting functions support at least three different
       // overloads, each intended for a different use case.

       // Use case 1: Manual Reset
       .italic()
       .append("This is italicized and reset manually.")
       // You can optionaly supply an additional append string
       // to any of the reset functions that will be appended
       // after the formating reset has been applied.
       .resetItalic(System.lineSeparator())

       // Use case 2: Automatic Reset
       .dim("This is dimmed and reset automatically.")
       .append(System.lineSeparator())

       // Use case 3: Function Consumer
       .underline(
           sb -> {
               // The string builder passed to this function consumer
               // will automatically wrap all content appended to it
               // with the underline formatting.
               sb.color24(
                   "#00ff00",
                   "This is both underlined and green"
               );
           }
       )
       .append(System.lineSeparator())

);

Java不“处理代码”，这是真的，但是Java输出你让它输出的东西。Windows控制台将ESC (chr(27))视为另一个符号(←)，这不是Java的错。

在Java中用红色打印任何文本的最佳解决方案是:

System.err.print("Hello World");

这个kotlin代码对我有用

import java.io.PrintStream

sealed class BackgroundColor(val value: Int) {
    object Default : BackgroundColor(0)

    // normal colors
    object Black : BackgroundColor(40)
    object Red : BackgroundColor(41)
    object Green : BackgroundColor(42)
    object Yellow : BackgroundColor(43)
    object Blue : BackgroundColor(44)
    object Magenta : BackgroundColor(45)
    object Cyan : BackgroundColor(46)
    object White : BackgroundColor(47)

    // colors with high contrast
    object BlackBright : BackgroundColor(100)
    object RedBright : BackgroundColor(101)
    object GreenBright : BackgroundColor(102)
    object YellowBright : BackgroundColor(103)
    object BlueBright : BackgroundColor(104)
    object MagentaBright : BackgroundColor(105)
    object CyanBright : BackgroundColor(106)
    object WhiteBright : BackgroundColor(107)
}

sealed class TextColor(val value: Int) {
    object Default : TextColor(0)

    // normal colors
    object Black : TextColor(30)
    object Red : TextColor(31)
    object Green : TextColor(32)
    object Yellow : TextColor(33)
    object Blue : TextColor(34)
    object Magenta : TextColor(35)
    object Cyan : TextColor(36)
    object White : TextColor(37)

    // colors with high contrast
    object BlackBright : TextColor(90)
    object RedBright : TextColor(91)
    object GreenBright : TextColor(92)
    object YellowBright : TextColor(93)
    object BlueBright : TextColor(94)
    object MagentaBright : TextColor(95)
    object CyanBright : TextColor(96)
    object WhiteBright : TextColor(97)
}

fun styleOutput(
    backgroundColor: BackgroundColor = BackgroundColor.Default,
    textColor: TextColor = TextColor.Default,
    boldText : Boolean = false,
    italicText : Boolean = false,
    underLineText : Boolean = false,
    action : PrintStream.() -> Unit
) {
    val styleFormat = StringBuilder("${27.toChar()}[${backgroundColor.value};${textColor.value}")

   if (boldText)
       styleFormat.append(";1")

    if (italicText)
        styleFormat.append(";3")

    if (underLineText)
        styleFormat.append(";4")

    styleFormat.append("m")

    print(styleFormat)
    System.out.action()
    print("${27.toChar()}[0m")
}

然后使用它

print("text without styling")
styleOutput(backgroundColor = BackgroundColor.Blue, textColor = TextColor.GreenBright, boldText = true) {
    print("text with styling")
}
print("text without styling")
