Java 枚举学习

1. 新建一个枚举类型

public enum ColorForUsing
{
RED("红色",0),
GREEN("绿色",1),
BLUE("蓝色",2),
ORENGE("橙色",3);

private String name;
private int index;

private ColorForUsing(String name,int index)
{
this.name = name;
this.index = index;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public int getIndex() {
return index;
}

public void setIndex(int index) {
this.index = index;
}

@Override
public String toString() {
// TODO Auto-generated method stub
StringBuilder str = new StringBuilder(this.getName()).append("-->").append(this.getIndex());
return str.toString();
}
}

2. 测试一下用法

public class Process {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
System.out.println(ColorForUsing.BLUE.toString());
}

}

3.到这里相信聪明的你已经完全懂了
