 Java Scripting > BeanShell > Scripted Methods

Scripted Methods 

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 writing scripted methods in beanshell script.

File Name  :  
/BEAN_SHELL001/config/scripted_meth.bsh 
   
//Plain Java
int sumStrict(int a, int b, int c) {
  return a + b + c;
}

//Loose Java
sumLoose(a, b, c) {
  return a + b + c;
}

int x = sumStrict(246);
print(x);

y = sumLoose(246);
print(y);

z = sumLoose(1.22.43.6);
print(z);

a = sumLoose("BE ""THE ""CODER");
print(a);

b = sumLoose("Name : ", name, " " + date);
print(b);

package com.bethecoder.tutorials.bean_shell;

import java.io.InputStreamReader;
import java.util.Date;

import bsh.EvalError;
import bsh.Interpreter;

public class ScriptedMethodsTest {

  /**
   @param args
   @throws EvalError 
   */
  public static void main(String[] argsthrows EvalError {
    Interpreter interpreter = new Interpreter();  
    interpreter.set("name""Sriram");            
    interpreter.set("date"new Date())

    InputStreamReader reader = new InputStreamReader(
        ScriptedMethodsTest.class.getClassLoader()
        .getResourceAsStream("scripted_meth.bsh"));
    interpreter.eval(reader);
  }

}
   

It gives the following output,
