How to retrieve a static variable using its name dynamically using Java reflection?

If I have class containing some variables:

public class myClass { 
     string [][] cfg1= {{"01"},{"02"},{"81"},{"82"}}; 
     string [][]cfg2=  {{"c01"},{"c02"},{"c81"},{"c82"}}; 
     string [][] cfg3=  {{"d01"},{"d02"},{"d81"}{"d82"}}; 
     int cfg11 = 5; 
     int cfg22 = 10; 
     int cfg33 = 15; 
 }

And in another class I want variable name is input from user:

class test { 
   Scanner in = new Scanner(System.in); 
   String userInput = in.nextLine();  
    // get variable from class myClass that  has the same name as userInput
   System.out.println("variable name " + // correct variable from class)
}

Using reflection. Any help please?
