Java Basic(45)-Enum Set range

import java.util.EnumSet; →滙入EnumSet

class apples{

public static void main(String args[]){

for(tuna people: tuna.values())

System.out.printf("%s\t%s\t%s\n", people, people.getDesc(),people.getYear());

System.out.println("\n And now for the range of constants!!!\n");

for (tuna people: EnumSet.range(tuna.kelsy, tuna.candy)) →從哪裡開始和結束

System.out.printf("%s\t%s\t%s\n", people, people.getDesc(),people.getYear());

}

}

public enum tuna {

bucky("nice","22"),

kelsy("cutie","10"),

julia("bigmistake","12"),

nicole("italian", "13"),

candy("different", "14"),

erin("iwish", "16");

private final String desc;

private final String year;

tuna(String description, String birthday){

desc=description;

year=birthday;

}

public String getDesc(){

return desc;

}

public String getYear(){

return year;

}

}

這是運行時的結果：

And now for the range of constants!!!

kelsy cutie 10

julia bigmistake 12

nicole italian 13

candy different 14
