The JTextField is a text field of a single line. Class inherits from the javax.swing.text.JTextComponent. Its methods include:

• public JTextField (int NumCols): creates a JTextField NumCols occupying columns. If it contains the text exceeds this size will not be lost even if it can not display all simultaneously;
• public JTextField (String text, int NumCols): same as above but also present an initial text;
• public void setFont (Font font): sets the font with which the text is displayed;
• public String getText () returns its content in left;
• public String getSelectedText (): returns the selected text inside;
• public void copy (): Copies the selected text to the system clipboard;
• public void cut (): same as above but also removes the selected text;
• public void setEditable (boolean b) Enables or disables the ability to change the text content.
