e1000. Using the Selection of a JTextComponent

    JTextComponent c = new JTextArea();
    
    // Get text inside selection
    c.getSelectedText();
    
    // Replace selected text
    c.replaceSelection("replacement text");
    
    // Set the start of the selection; ignored if new start is < end
    c.setSelectionStart(10);
    
    // Set the end of the selection; ignored if new end is > start
    c.setSelectionEnd(20);
    
    // Better way to set the selection
    c.select(10, 20);
    
    // Set the color of text inside the selection
    c.setSelectedTextColor(Color.red);
    
    // Set the color behind the selected text
    c.setSelectionColor(Color.green);
