This example show you how to use enumeration or enum
type in a switch
statement.
package org.kodejava.basic;
public enum RainbowColor {
RED, ORANGE, YELLOW, GREEN, BLUE, INDIGO, VIOLET
}
package org.kodejava.basic;
public class EnumSwitch {
public static void main(String[] args) {
RainbowColor color = RainbowColor.INDIGO;
EnumSwitch es = new EnumSwitch();
String colorCode = es.getColorCode(color);
System.out.println("ColorCode = #" + colorCode);
}
public String getColorCode(RainbowColor color) {
String colorCode = "";
// We use the switch-case statement to get the hex color code of our
// enum type rainbow colors. We can pass the enum type as expression
// in the switch. In the case statement we only use the enum named
// constant excluding its type name.
switch (color) {
// We use RED instead of RainbowColor.RED
case RED -> colorCode = "FF0000";
case ORANGE -> colorCode = "FFA500";
case YELLOW -> colorCode = "FFFF00";
case GREEN -> colorCode = "008000";
case BLUE -> colorCode = "0000FF";
case INDIGO -> colorCode = "4B0082";
case VIOLET -> colorCode = "EE82EE";
}
return colorCode;
}
}
