嗨，我正在尝试在 Jdialog 中打印主框架中选定行的值。
我正在尝试这个，但是当我在主框架中调用方法(“m.SetRecoger)时，它显示了这个错误:
“类 Modificar 中的方法 SetRecoger 不能应用于给定类型；
必需:字符串[]
发现:没有参数
原因:实际参数列表和形式参数列表的长度不同”
完整代码:
我有jtable的主框架:

谢谢!!
最佳答案
您正在调用方法 SetRecoger在您的 DniFrame不向方法传递任何参数。
您在 Modificar 中定义的方法对话框需要一个字符串数组作为参数。
public void SetRecoger(String[] v) {....}
由于您的
modify()方法返回一个字符串数组，试试这个:String[] mod = modify();
Modificar m = new Modificar(this, true);
m.SetRecoger(mod);
new Modificar(this, true).setVisible(true);
关于java - 参数数组字符串Jframe，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/21867934/
