java 8 - Updating an attribute of an element in list with matching attribute

I am new to Java 8. I have a list of objects of class A, where structure of A is as follows:

class A {
   int name,
   boolean isActive
}

Now I have a list of elements L of class A, in that list I want to update an element having name="test" with inactive=false.

I can do this very easily by writing a for loop and creating a new list.

But how would I do that using Java 8 stream API?

You can do it like this.

L.stream()
.filter(item-> item.getName().equals("test"))
.forEachOrdered(a -> a.setActiv(false));

I believe data type of name should be String not int in your question
