SimpleScriptContext getBindings() method in Java with Examples

The getBindings() method of a SimpleScriptContext class is used to return the bindings associated with the given scope in this ScriptContext where scope is passed as parameter.

Syntax:

Bindings getBindings(int scope)

Parameters: This method accepts a single parameter scope which is the scope in this ScriptContext.

Return value: This method returns associated Bindings and returns null if it has not been set.

Exceptions: This method throws following Exceptions:

• IllegalArgumentException: If no Bindings is defined for the specified scope value in ScriptContext of this type.

Below programs illustrate the SimpleScriptContext.getBindings() method:
Program 1:

// Java program to demonstrate
// SimpleScriptContext.getBindings() method

import javax.script.Bindings;
import javax.script.ScriptContext;
import javax.script.SimpleScriptContext;

public class GFG {
    public static void main(String[] args)
    {

        // create SimpleScriptContext object
        SimpleScriptContext simple
            = new SimpleScriptContext();

        // add some attribute
        simple.setAttribute(
            "name1",
            "Value1",
            ScriptContext.ENGINE_SCOPE);
        simple.setAttribute(
            "name2",
            "Value2",
            ScriptContext.ENGINE_SCOPE);

        // get bindings using getBindings()
        Bindings bindings
            = simple.getBindings(
                ScriptContext.ENGINE_SCOPE);

        // print
        System.out.println("Bindings value for name1:"
                           + bindings.get("name1"));
        System.out.println("Bindings value for name2:"
                           + bindings.get("name2"));
    }
}

Output:

Bindings value for name1:Value1
Bindings value for name2:Value2

Program 2:

// Java program to demonstrate
// SimpleScriptContext.getBindings() method

import javax.script.Bindings;
import javax.script.ScriptContext;
import javax.script.SimpleScriptContext;

public class GFG {
    public static void main(String[] args)
    {

        // create SimpleScriptContext object
        SimpleScriptContext simple
            = new SimpleScriptContext();

        // add some attribute
        simple.setAttribute(
            "Team1",
            "India",
            ScriptContext.ENGINE_SCOPE);
        simple.setAttribute(
            "Team2",
            "Japan",
            ScriptContext.ENGINE_SCOPE);
        simple.setAttribute(
            "Team3",
            "Nepal",
            ScriptContext.ENGINE_SCOPE);

        // get bindings using getBindings()
        Bindings bindings
            = simple.getBindings(
                ScriptContext.ENGINE_SCOPE);

        // print
        System.out.println("Bindings value for Team1:"
                           + bindings.get("Team1"));
        System.out.println("Bindings value for Team2:"
                           + bindings.get("Team2"));
        System.out.println("Bindings value for Team3:"
                           + bindings.get("Team3"));
    }
}

Output:

Bindings value for Team1:India
Bindings value for Team2:Japan
Bindings value for Team3:Nepal
