定义一个枚举类
//枚举类型
public enum test122 {
RED,
GREEN,
BLUE;
}
测试类
public class test123 {
public static void main(String[] args){
System.out.println( test122.BLUE );
test122[] sigs=test122.values();
for(test122 e:sigs){
System.out.println( "枚举名称" +e.name());
System.out.println( "枚举的索引" +e.ordinal());
}
}
}
