我如何在控制台打印颜色?当处理器发送数据时，我想用不同的颜色显示数据，当处理器接收数据时，我想用不同的颜色显示数据。

使用颜色功能打印带有颜色的文本
代码:
enum Color {
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
private final String code
Color(String code) {
this.code = code;
}
@Override
String toString() {
return code
}
}
def color = { color, txt ->
def RESET_COLOR = "\033[0m"
return "${color}${txt}${RESET_COLOR}"
}
用法:
test {
println color(Color.CYAN, 'testing')
}

下面是带有公共静态字段的Java类中的颜色列表
使用
System.out.println(ConsoleColors.RED + "RED COLORED" +
ConsoleColors.RESET + " NORMAL");
请注意 不要忘记在打印后使用RESET，因为如果它没有被清除，效果将仍然存在
public class ConsoleColors {
// Reset
public static final String RESET = "\033[0m"; // Text Reset
// Regular Colors
public static final String BLACK = "\033[0;30m"; // BLACK
public static final String RED = "\033[0;31m"; // RED
public static final String GREEN = "\033[0;32m"; // GREEN
public static final String YELLOW = "\033[0;33m"; // YELLOW
public static final String BLUE = "\033[0;34m"; // BLUE
public static final String PURPLE = "\033[0;35m"; // PURPLE
public static final String CYAN = "\033[0;36m"; // CYAN
public static final String WHITE = "\033[0;37m"; // WHITE
// Bold
public static final String BLACK_BOLD = "\033[1;30m"; // BLACK

public static final String CYAN_BOLD = "\033[1;36m"; // CYAN
public static final String WHITE_BOLD = "\033[1;37m"; // WHITE
// Underline
public static final String BLACK_UNDERLINED = "\033[4;30m"; // BLACK
public static final String RED_UNDERLINED = "\033[4;31m"; // RED
public static final String GREEN_UNDERLINED = "\033[4;32m"; // GREEN
public static final String YELLOW_UNDERLINED = "\033[4;33m"; // YELLOW
public static final String BLUE_UNDERLINED = "\033[4;34m"; // BLUE
public static final String PURPLE_UNDERLINED = "\033[4;35m"; // PURPLE
public static final String CYAN_UNDERLINED = "\033[4;36m"; // CYAN
public static final String WHITE_UNDERLINED = "\033[4;37m"; // WHITE
// Background

public static final String CYAN_BACKGROUND = "\033[46m"; // CYAN
public static final String WHITE_BACKGROUND = "\033[47m"; // WHITE
// High Intensity
public static final String BLACK_BRIGHT = "\033[0;90m"; // BLACK
public static final String RED_BRIGHT = "\033[0;91m"; // RED
public static final String GREEN_BRIGHT = "\033[0;92m"; // GREEN
public static final String YELLOW_BRIGHT = "\033[0;93m"; // YELLOW
public static final String BLUE_BRIGHT = "\033[0;94m"; // BLUE
public static final String PURPLE_BRIGHT = "\033[0;95m"; // PURPLE
public static final String CYAN_BRIGHT = "\033[0;96m"; // CYAN
public static final String WHITE_BRIGHT = "\033[0;97m"; // WHITE
// Bold High Intensity
public static final String BLACK_BOLD_BRIGHT = "\033[1;90m"; // BLACK
public static final String RED_BOLD_BRIGHT = "\033[1;91m"; // RED

public static final String GREEN_BACKGROUND_BRIGHT = "\033[0;102m";// GREEN
public static final String YELLOW_BACKGROUND_BRIGHT = "\033[0;103m";// YELLOW
public static final String BLUE_BACKGROUND_BRIGHT = "\033[0;104m";// BLUE
public static final String PURPLE_BACKGROUND_BRIGHT = "\033[0;105m"; // PURPLE
public static final String CYAN_BACKGROUND_BRIGHT = "\033[0;106m"; // CYAN
public static final String WHITE_BACKGROUND_BRIGHT = "\033[0;107m"; // WHITE
}
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

private final String code;
Color(String code) {
this.code = code;
}
@Override
public String toString() {

}
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);
}
}
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")
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())
);
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");
