java getConstructor(String[].class)

Question

我尝试了以下代码:

constructor = oneClass.getConstructor(new Class[]{String[].class});

return constructor.newInstance(new String[]{"String01","String02"})

(return 语句返回 IllegalArgumentException)

还有

Class stringArray = Class.forName("[Ljava.lang.String;");

constructor = oneClass.getConstructor(new Class[]{stringArray})

return constructor.newInstance(new String[]{"String01","String02"})

(return 语句返回 IllegalArgumentException)

如何表达我想用 String[] 作为参数实例化构造函数。

谢谢。

Answer 1

这个怎么样:

constructor = oneClass.getConstructor(String[].class);
return constructor.newInstance(new Object[]{new String[]{"String01","String02"}})

假设你的构造函数是这样的:

public class OneClass
{
    public OneClass(String[] args)
    {
        // ...
    }
}
