Dynamic variable names Java
<p>How will I be able to retreive value of variable which has a dynamic name</p>

<p>For Example I have list of constants</p>

<pre><code>public class Constant{
    public static final String S_R = "Standard(240)";
    public static final String S_W = "Standard(180)";
    public static final String L_R = "Large(360)";
    public static final String L_W = "Large(280)";
}
</code></pre>

<p>Based on database I build a variable name </p>

<pre><code>String varName = "S" + "_"  +"R"; // This can be S_R , S_W , L_R or L_W
String varVal = // How do i get value of S_R
</code></pre>
