With line-wrapping, breaks are allowed to occur in the middle of words. With word-wrapping, breaks are only allowed between words. 
    JTextArea c = new JTextArea();
    
    // Enable line-wrapping
    c.setLineWrap(true);
    c.setWrapStyleWord(false);
    
    // Enable word-wrapping
    c.setLineWrap(true);
    c.setWrapStyleWord(true);
