您好我需要个人项目的帮助。我正在开发一个软件来管理节目(事件),我有问题要保存并反对我的课堂内的arraylist。 我有3个对象,艺术家,事件,合同,每次用户签订合同,在艺术家和代理之间,我希望能够将艺术家保存到代理类内的agentContract中。因为我需要每个代理人的艺术家名单。我的问题是每次我尝试保存时,我的程序只保存第一个代理中的所有艺术家。有人可以帮助我吗?
这是我的艺术家课程:
public class Agent extends Person implements Serializable {
float dueAmount;
int percentage;
public static ArrayList<Artist> AgentArtists = new ArrayList<Artist>();
public Agent()
{
super();
dueAmount = 0;
percentage = 0;
}
..... .....
public static ArrayList<Artist> getAgentArtists()
{
return AgentArtists;
}
public void setAgentArtists(Agent age,Artist art)
{
age.AgentArtists.add(art);
}
我使用此方法签署合同并将艺术家保存到座席的艺术家列表中
public void SignWithArtist(Artist art, Agent age)
{
if (age.getAgentArtists().add(art) == true)
{
System.out.println("\n" + art.getName() + " is signing the contract\n");
ProgManage.PauseScreen(1000);
for(int i=0; i<=1; i++)
{
System.out.print("*");
ProgManage.PauseScreen(1000);
System.out.print("**");
ProgManage.PauseScreen(1000);
System.out.print("***");
ProgManage.PauseScreen(1000);
System.out.print("****");
ProgManage.PauseScreen(1000);
}
System.out.println("\nContract signed by " + art.getName());
ProgManage.PauseScreen(1000);
} else {
System.out.println("\n*ERROR* Artist not added");
ProgManage.PauseScreen(1000);
}
}
答案 0 :(得分:0)
试试这段代码:
public class Agent extends Person implements Serializable {
float dueAmount;
int percentage;
public ArrayList<Artist> agentArtists;
public Agent()
{
super();
agentArtists = new ArrayList<Artist>();
dueAmount = 0;
percentage = 0;
}
public ArrayList<Artist> getAgentArtists()
{
return agentArtists;
}
public void setAgentArtists(Artist art)
{
agentArtists.add(art);
}
}
