          I think what you are looking for is .equals() method of String class which can compare two strings. For example: 



          if(scanner.next().equals(a)) {
          
   // do something
          
}

            I'm not very clear about your question. Do you mean user will input a variable name, and the program need to display the value of this variable?



            If my guess correct, you just need a map. For example, if your variable value type is Integer, you can create:
            Map memory = newHashMap();



            and put your initialized variable into "memory" by: memory.put("var", 1).



            to retrieve the variable: if ( memory.containsKey("var") ) return memory.get("var");
