------解决方案--------------------
你的object[]是怎么得来的
如果类似将list转成String[],即list.toArray(new String[0]);

------解决方案--------------------
应该这样调用
Java code

import java.util.List;
import java.util.ArrayList;

public class TransferStrAry {
    public static void main(String[] args) {
        List list = new ArrayList();
        list.add("asdfasdf");
        list.add("sfh");
        list.add("345");
        String[] str =new String[list.size()];
        list.toArray(str);
        for(String s:str){
            System.out.println(s);
        }
    }
}

------解决方案--------------------
String[] str=list.toArray(new String[0]);

------解决方案--------------------
Java code

        List list = new ArrayList();
        list.add("asdfasdf");
        list.add("sfh");
        list.add("345");
        String[] str = (String[]) list.toArray(new String[0]);
        System.out.println(str.length);
