The put() method of SimpleBindings class is used to add the specified key and value pair in the SimpleBindings object. Both key and value are passed as parameters. The key renamed as a name for the value to set in SimpleBindings object. After setting the value method returns the previous value for the specified key and it will return null if the key was previously unset.
Syntax:
public Object put(String name, Object value)
Parameters: This method accepts two parameters:
- name which is Name of value and
- value which is the Value to set.
Return Value: This method returns the previous value for the specified key and it will return null if the key was previously unset.
Exception: This method throws following exceptions:
- NullPointerException: if the specified name is null
- IllegalArgumentException: if the specified name is empty String
Java programs to Illustrate the working of put() method:
Program 1:
Java
import javax.script.SimpleBindings;
public class GFG {
public static void main(String[] args)
{
SimpleBindings bindings
= new SimpleBindings();
bindings.put( "key1" , "value1" );
bindings.put( "key2" , "value2" );
bindings.put( "key3" , "value3" );
System.out.println( "Key1: "
+ bindings.get( "key1" ));
System.out.println( "Key2: "
+ bindings.get( "key2" ));
System.out.println( "Key3: "
+ bindings.get( "key3" ));
}
}

Output:
Key1: value1
Key2: value2
Key3: value3
Program 2:
Java
import javax.script.SimpleBindings;
public class GFG {
public static void main(String[] args)
{
SimpleBindings asiaTeamList
= new SimpleBindings();
asiaTeamList.put( "team1" , "India" );
asiaTeamList.put( "team2" , "Sri Lanka" );
asiaTeamList.put( "team3" , "Pakistan" );
asiaTeamList.put( "team4" , "Bangladesh" );
System.out.println(
asiaTeamList.get( "team1" ));
System.out.println(
asiaTeamList.get( "team2" ));
System.out.println(
asiaTeamList.get( "team3" ));
System.out.println(
asiaTeamList.get( "team4" ));
}
}

Output:
India
