We can even make some function in BeanShell

add(a,b)
{sum = a+b;
print(sum);
}

Then we call this function any number of time we want

add(7,5);
add(5,10);

As we have not defined the type of a and b so func is a untyped function.So it can accept any type of arguments when it is called be it integers,double or String etc.

add("Hi", "there");

Typed func-Which accept arguments of a particular data type and return data of a particular type like String.

String conc(String a,String b){
return a.concat(b);
}

Then we can call it

print(conc("A","D"));

We can even write a function in an external file and call the function from the same file.

Then we can save this function as with .bsh extension in double quotes.

Void helloworld(){
System.out.println(“Hell0”)
}
helloworld();

Save it as “externalbsh.bsh”

Then make a new Bean Shell Sampler in our project and instead of typig something in script we choose the external file and we run it.
