How to Add Color to Console Output Using System.out.println()?

How to Inject Color into Console Output with System.out.println()

Question:

How do I effortlessly infuse color into my console output to visually differentiate data?

Answer:

Embracing the power of ANSI escape codes, you can unleash a vibrant spectrum of colors in your console output. This technique, predominantly supported by Unix shell prompts, provides a convenient way to enhance data presentation. If you wish to enchant your terminals with this chromatic magic, simply follow these steps:

1. Define constants representing your desired color palette, as showcased below:

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";

2. To illustrate, let's paint our console a vibrant shade of red:

System.out.println(ANSI_RED + "This text dances in fiery crimson!" + ANSI_RESET);

3. Should you desire to venture beyond text color, you can also alter the background hue:

public static final String ANSI_BLACK_BACKGROUND = "\u001B[40m";
public static final String ANSI_RED_BACKGROUND = "\u001B[41m";
public static final String ANSI_GREEN_BACKGROUND = "\u001B[42m";
public static final String ANSI_YELLOW_BACKGROUND = "\u001B[43m";

System.out.println(ANSI_GREEN_BACKGROUND + "Emerald hues adorn this text's canvas!" + ANSI_RESET);

4. For added versatility, consider exploring the Jansi library. It seamlessly integrates with Windows using JNI, opening up a world of colorful possibilities.
5. Remember that these vibrant transformations may only grace terminals that acknowledge ANSI escape codes. If your Windows Command Prompt stubbornly resists, Cygwin may offer a compatible alternative.

With this newfound control over console colors, you can effortlessly transform data into a visual masterpiece, adding depth and clarity to your programs' output.
