How to print string on JTextField

Question

I want to show String b up on TextField . String b is a conversion of array of stringChar .

void setTextField(char s) {
     stringChar[index] = s;
     index++;
     String b = new String(string);
     System.out.println(b);
     TextField.setText(b);
}

If I execute the code, then the String is not displayed in the textfield.

Answer 1

You said: I want to show string b up on TextField. string b is a converion of array of stringChar.

But in the code you wrote: String b = new String(string);

Instead of that is should be: String b = new String(stringChar);

Also, you should repaint the textfield: TextField.repaint();

Answer 2

Blockquote JTextArea.setText(string); JTextArea.append(string);
