请问数组赋值问题?

[cool_sky]

请问我再bo里这样定义属性
public String[] getChannel_value() {
return channel_value;
}
public void setChannel_value(String[] channel_value) {
this.channel_value = channel_value;
}

赋值时可以这样赋值吗??
while (rs.next()) {
bo.setChannel_value(rs.getString("channel_value"));
}

还是这样可以?
String[] channel_value;
int sum=0;
while (rs.next()) {
channel_value[sum++]=rs.getString("channel_value");

}
bo.setChannel_value(channle_value);
