您正在使用, 而不是 + 进行字符串连接

JOptionPane.showMessageDialog("Employee Id Is  "+
 empid , "\nEmploye Name is  " + employeename +
"\nFather Name is " + fathername +
"\nJob Catagory is  " + jobcatagory +
"\nAge is  " + age +
"\nEducation is  " + education +
"\nPay Scale is   " + payscal+
"\nNIC is  " + NIC );

而且您将错误的参数传递给 showMessageDialog() 方法。

请在此处参考 JOptionPane 及其方法签名

javax.swing.JOptionPane 提供了三个重写方法：

javax.swing.JOptionPane.showMessageDialog(java.awt.Component,java.lang.Object,java.lang.String,int,javax.swing.Icon) 
javax.swing.JOptionPane.showMessageDialog(java.awt.Component,java.lang.Object,java.lang.String,int)
javax.swing.JOptionPane.showMessageDialog(java.awt.Component,java.lang.Object)

您正在调用该类中未定义的方法：

showMessageDialog(java.lang.String,java.lang.String,java.lang.String,java.lang.String,java.lang.String,java.lang.String,java.lang.String,java.lang.String)

我想“，”而不是“+”有问题。

您忘记了输出语句之前的空值，如 JOptionPane.showMessageDialog(null, "...."); 而且你不能使用“，”，只能使用“+”

JOptionPane.showMessageDialog(null,"Your text "+anyVariable+"any more text",
    "The BoxHeader title", JOptionPane.PLAIN_MESSAGE);

您必须先放null，然后不要忘记“Box header title”，后跟逗号（，）和JOptionPane.PLAIN_MESSAGE
