How to remove JTextArea line around rectangle (border)

 code:

textarea.setBorder(null);

In NetBeans:
1. Click the text area
2. Go to Properties
3. Scroll to Other Properties
4. Go to border then select (No Border)

5. Put this in your constructor:

jScrollPane1.setBorder(null);

This is because NetBeans automatically creates scrollpane to your text area and its border is visible until you set it to null.

6. Run the file to see the result.

It worked for me just fine :)

How to resize ImageIcon - Java

Please make reading a habit :)

 This was my problem before. After  days of searching, I combined the codes of my search items and came up with this:

-- start of function. I put it inside a function --

//gets the directory of the file

//this means that the file name is where the directory is plus the folder pictures plus the filename

//which is hold by the string named idnumber

idnumber = "CO00001";

dir_pic = System.getProperty("user.dir"); 

dir_pic = dir_pic+"\\Pictures\\"+idnumber+".jpg";

//you could simply put the path of the image in dir_pic variable

//We should have an image first.

//For me, I open the image from my directory

File file = new File(dir_pic); 

image = ImageIO.read(file); //reads the image

//this sets the image to an Image Icon
ImageIcon icon = new ImageIcon(image);

//we start to scale here

//first get the image from ImageIcon
Image img = icon.getImage();

//then scale it; I scaled it to 120x120

//please check the documentation for parameter listing if u dont want SCALE_SMOOTH

Image newimg = img.getScaledInstance(120, 120,java.awt.Image.SCALE_SMOOTH); 

newIcon = new ImageIcon(newimg); //we now have new icon - scaled by 120x120

//I made a JLabel named label and put the image there

label = new JLabel(new ImageIcon(newimg)); 

//then put the label to a square panel

picpanel.add(label); 

label.setBounds(2, 2, 115, 105); //change the bounds according to your design

--- end of function ---
