Chapter 13, Problem 10AW

Explanation of Solution

Text Area:

• A text area is a multiline text field that can take many lines of input.
• Components in the text area are inherited from the “JComponent” class.
• User can create the text areas by using “JTextArea” class.
• A text area contains two constructors.
  • JTextArea(int rowsCount, int columnsCount)
    • This constructor takes an argument as number of rows and number of columns.
  • JTextArea(String inputText, int rowsCount, int columnsCount)
    • This constructor takes the argument of string (that is for initial text), number of rows and columns.
• Using “JScrollPane”, the user can display scroll bars on a “JTextArea” component.
  • First, the user needs to create a text area and then, add it to an object of scroll pane
• User can enable the text wrapping by using “setLineWrap()” method.
  • This method takes a “boolean” argument.
  • If the user passes the argument as “true”, then text wrapping is enabled.
  • Otherwise, the text wrapping is disabled.
• For text area, there are two styles of line wrapping in text area such as word and character wrapping.
  • User can identify the line wrapping style using “setWrapStyleWord” method...
