Question

您好我正在尝试在Jdialog中打印主框架中所选行的值。我正在尝试这个，但是当我在主框架中调用方法（“m.SetRecoger”）时显示此错误：

“类Modificar中的方法SetRecoger不能应用于给定类型; 必需：String [] 发现：没有争论原因：实际和正式的参数列表长度不同“

完整的代码：

我有jtable的主框架：公共类DniFrame扩展了javax.swing.JFrame {

您正在调用SetRecoger中的方法DniFrame，而不向该方法传递任何参数。

您在Modificar对话框中定义的方法需要String数组作为参数。

public void SetRecoger(String[] v) {....}

由于您的modify()方法返回一个String数组，请尝试以下方法：

String[] mod = modify(); 
Modificar m = new Modificar(this, true);
m.SetRecoger(mod);
new Modificar(this, true).setVisible(true);

参数数组字符串Jframe
