As far as config file concern, this is just string variable which may used in program to split later point of time where it used..

Solution 2:[2]

In a Java properties file the "&" does not have a special meaning - in fact it is just another character like a, b or c. However once the key/value pair is loaded by some application the value containing the "&" can get meaning. For example there is a common usecase when the key describes a menu entry and ampersand is the key to access the entry quickly. There is also a Java Tutorial from Oracle about properties:

If it is still needed

It seems that for SWT related usage (e.g. Eclipse Preference View & Run Configuration) the "&" char is used to prefix a specific char, making it underline during the rendering and selectable by keybord shortcut alt+char.
