Get data from BeanShell 

BeanShell is a small, free, embeddable Java source interpreter with object scripting language features, written in Java. BeanShell is a natural scripting language for Java. This requires the library bsh-2.0b4.jar to be in classpath. The following example shows retrieving beanshell scripting variables from the interpreter in Java.

print("Calculating Area");
area = Math.PI * Math.pow(radius, 2);
print("Area Calculation completed");

package com.bethecoder.tutorials.bean_shell;


import bsh.EvalError;
import bsh.Interpreter;

public class AccessFromAppTest {

   @param args
   @throws EvalError 
  public static void main(String[] argsthrows EvalError {
    Interpreter interpreter = new Interpreter();  

    InputStreamReader reader = new InputStreamReader(
    Double area = (Doubleinterpreter.get("area");
    System.out.println("Area of Circle : " + area);


It gives the following output,
Calculating Area
Area Calculation completed
Area of Circle : 50.26548245743669
