In this tutorial, we will learn basic implementations for Callable interface using lambda in java. Anonymous Class providing an implementation for Callable interface. Callable<String> callMyName = new Callable<String>() { @Override public String call() throws Exception { return “Anurag Anand”; } }; You can submit the above implementation to return any string value. The same can be […]
Using lambda and Functional Programming to provide implementation for Callable interface – which prints a string n number of times in java
Callable is a Functional interface, it is similar in usage to Runnable interface. But with a small difference, that Callable can return a value, while Runnable can not return a value. In this tutorial, we will create a Callable which will return a String output. The string output is going to return String Value, which will be contain a given word repeated n number of times. Given Values :- […]
What is lambdas in Java – Understanding Lamdas in Java
Lambdas were introduced in Java 8. For me they are first step towards functional programming in java. Lambdas are a little like anonymous class. They are similar in the way they are defined and passed around as a parameter in functions. But, lambdas are not exactly an anonymous class. After compilation, an anonymous class has […]
