导入软件包时出错

Question

package textar;
import java.awt.*;
import javax.swing.*;
public class textarea extends JInternalFrame
{
     public static JTextArea txtaMessage;
     textarea() {
         super("Private Cloud Environment",true,false,true,true);       
         txtaMessage=new JTextArea();
         JScrollPane  scrollPane=newJScrollPane(txtaMessage,
                                    JScrollPane.VERTICAL_SCROLLBAR_ALWAYS,
                                    JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
         txtaMessage.setFont(new Font("Serif", Font.BOLD, 16));
         txtaMessage.setEditable(false);
         getContentPane().setLayout(new GridLayout(1,1));
         getContentPane().add(scrollPane);
         setSize(650,650);
         setVisible(true);
     }
}

So above is my block of code which has to b called in the followin program

import package textar.*;
public Main()
{                   
    //creating object for textarea InternalFrame
    textarea objtxta=new textarea();
    addFrame(objtxta);
}

but when compiling

  import package textar.*;
  ^
  1 error

  "error: identifier expected" pops out !! 

I hav skipped other parts of d program because they have nothing to do with the package.

Help me out please !! And Thanks in advance !!

Answer 1

The use of the package keyword is invalid in import statement here. You can use:

import textar.*;

Your calling class does not appear to have the class declared:

import textar.*;

public class Main {

   public Main() {                   
    //creating object for textarea InternalFrame
    textarea objtxta=new textarea();
    addFrame(objtxta);
   }
   ...

Also there should be spaces between the keywords in the declaration of JScrollPane in the textarea class:

JScrollPane scrollPane = new JScrollPane(txtaMessage,
                JScrollPane.VERTICAL_SCROLLBAR_ALWAYS,
                JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
