[Solved] I am replacing value “Kumar” with “Singh” while Iterating ArrayList using Java 7, How it will convert using Java 8 Stream API?

You can do like below:

Method:1

 namesList1.forEach(name -> {
        if (name.equalsIgnoreCase("Kumar")) {
            namesList1.set(namesList1.indexOf(name), "Singh");
        }
    });
    System.out.println(namesList1);

Method :2 (Suggested by @Holger)

namesList1.replaceAll(s -> s.equalsIgnoreCase("Kumar")? "Singh": s);
System.out.println(namesList1);
