問題：怎么樣用System.out.println在控制臺打印出顏色

怎么樣才能在控制臺里打印顏色啊？我想要展示一些有顏色的字體，當處理器發送數據和接收數據的時候，也使用不同顏色的字體。

在這個Java類里面帶有public static 的數據域里面有一系列的顏色。

用法

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

記住千萬不要忘記在打印以后重置，沒有清理的話，那個效果會一直保留的。

public class ConsoleColors {// Resetpublic static final String RESET = "\033[0m";  // Text Reset// Regular Colorspublic static final String BLACK = "\033[0;30m";   // BLACKpublic static final String RED = "\033[0;31m";     // REDpublic static final String GREEN = "\033[0;32m";   // GREENpublic static final String YELLOW = "\033[0;33m";  // YELLOWpublic static final String BLUE = "\033[0;34m";    // BLUEpublic static final String PURPLE = "\033[0;35m";  // PURPLEpublic static final String CYAN = "\033[0;36m";    // CYANpublic static final String WHITE = "\033[0;37m";   // WHITE// Boldpublic static final String BLACK_BOLD = "\033[1;30m";  // BLACKpublic static final String RED_BOLD = "\033[1;31m";    // REDpublic static final String GREEN_BOLD = "\033[1;32m";  // GREENpublic static final String YELLOW_BOLD = "\033[1;33m"; // YELLOWpublic static final String BLUE_BOLD = "\033[1;34m";   // BLUEpublic static final String PURPLE_BOLD = "\033[1;35m"; // PURPLEpublic static final String CYAN_BOLD = "\033[1;36m";   // CYANpublic static final String WHITE_BOLD = "\033[1;37m";  // WHITE// Underlinepublic static final String BLACK_UNDERLINED = "\033[4;30m";  // BLACKpublic static final String RED_UNDERLINED = "\033[4;31m";    // REDpublic static final String GREEN_UNDERLINED = "\033[4;32m";  // GREENpublic static final String YELLOW_UNDERLINED = "\033[4;33m"; // YELLOWpublic static final String BLUE_UNDERLINED = "\033[4;34m";   // BLUEpublic static final String PURPLE_UNDERLINED = "\033[4;35m"; // PURPLEpublic static final String CYAN_UNDERLINED = "\033[4;36m";   // CYANpublic static final String WHITE_UNDERLINED = "\033[4;37m";  // WHITE// Backgroundpublic static final String BLACK_BACKGROUND = "\033[40m";  // BLACKpublic static final String RED_BACKGROUND = "\033[41m";    // REDpublic static final String GREEN_BACKGROUND = "\033[42m";  // GREENpublic static final String YELLOW_BACKGROUND = "\033[43m"; // YELLOWpublic static final String BLUE_BACKGROUND = "\033[44m";   // BLUEpublic static final String PURPLE_BACKGROUND = "\033[45m"; // PURPLEpublic static final String CYAN_BACKGROUND = "\033[46m";   // CYANpublic static final String WHITE_BACKGROUND = "\033[47m";  // WHITE// High Intensitypublic static final String BLACK_BRIGHT = "\033[0;90m";  // BLACKpublic static final String RED_BRIGHT = "\033[0;91m";    // REDpublic static final String GREEN_BRIGHT = "\033[0;92m";  // GREENpublic static final String YELLOW_BRIGHT = "\033[0;93m"; // YELLOWpublic static final String BLUE_BRIGHT = "\033[0;94m";   // BLUEpublic static final String PURPLE_BRIGHT = "\033[0;95m"; // PURPLEpublic static final String CYAN_BRIGHT = "\033[0;96m";   // CYANpublic static final String WHITE_BRIGHT = "\033[0;97m";  // WHITE// Bold High Intensitypublic static final String BLACK_BOLD_BRIGHT = "\033[1;90m"; // BLACKpublic static final String RED_BOLD_BRIGHT = "\033[1;91m";   // REDpublic static final String GREEN_BOLD_BRIGHT = "\033[1;92m"; // GREENpublic static final String YELLOW_BOLD_BRIGHT = "\033[1;93m";// YELLOWpublic static final String BLUE_BOLD_BRIGHT = "\033[1;94m";  // BLUEpublic static final String PURPLE_BOLD_BRIGHT = "\033[1;95m";// PURPLEpublic static final String CYAN_BOLD_BRIGHT = "\033[1;96m";  // CYANpublic static final String WHITE_BOLD_BRIGHT = "\033[1;97m"; // WHITE// High Intensity backgroundspublic static final String BLACK_BACKGROUND_BRIGHT = "\033[0;100m";// BLACKpublic static final String RED_BACKGROUND_BRIGHT = "\033[0;101m";// REDpublic static final String GREEN_BACKGROUND_BRIGHT = "\033[0;102m";// GREENpublic static final String YELLOW_BACKGROUND_BRIGHT = "\033[0;103m";// YELLOWpublic static final String BLUE_BACKGROUND_BRIGHT = "\033[0;104m";// BLUEpublic static final String PURPLE_BACKGROUND_BRIGHT = "\033[0;105m"; // PURPLEpublic static final String CYAN_BACKGROUND_BRIGHT = "\033[0;106m";  // CYANpublic static final String WHITE_BACKGROUND_BRIGHT = "\033[0;107m";   // WHITE}

使用顏色函數打印帶有顏色的文本

代碼:

enum Color {RED("\033[0;31m"),      // REDGREEN("\033[0;32m"),    // GREENYELLOW("\033[0;33m"),   // YELLOWBLUE("\033[0;34m"),     // BLUEMAGENTA("\033[0;35m"),  // MAGENTACYAN("\033[0;36m"),     // CYANprivate final String codeColor(String code) {this.code = code;}@OverrideString 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')
}
