How to Convert List to Map in Java 8

Core Java » On Oct 26, 2016 { 1 Comment } By Sivateja

If you have a scenario where you need to convert List of objects to a Map, prior to java 8 you can do this by writing a simple for loop which is iterative. But in this article I will show you how to convert List to Map using java 8 lambda expression.

Java 8 Convert List to Map Example

Lets a take pojo class named Account with properties accNo, accType, accStatus.

Account.java

ListtoMap.java

Output

Before Java 8 {100=Open, 101=Closed}
Java 8  {100=Open, 101=Closed}

Hey its same output ;) I just tried to show both ways [ with and without lambda expression ].
