枚举定义:
public enum SizeEnum {
SMALL,
BIG,
BIGEST
};
public enum SizeStringEnum { SMALL("小"),
BIG("大"),
BIGEST("巨大"); private String strSizeString; public String toString() {
return strSizeString;
}
private SizeStringEnum(String str) {
this.strSizeString = str; } }
常用方法:
1、values():
获取当前枚举的所有对象属性:
如:
//1、
SizeStringEnum sizeStringEnum=SizeStringEnum.BIG;
for(SizeStringEnum size: sizeStringEnum.values())
{
System.out.println(size);
} //2、
for(SizeStringEnum size: SizeStringEnum.values())
{
System.out.println(size);
}
2、Enum.valueOf
通过枚举值寻找枚举对象
sizeStringEnum=Enum.valueOf(SizeStringEnum.class, "BIG");
