The File class of the java.io package is used to perform various operations on files and directories. There is another package named java.nio that can be used to work with files. However, in this tutorial, we will focus on the java.io package. File and Directory… Continue reading  File Class

In this tutorial, we will learn about Java Generics, how to create generics class and methods and its advantages with the help of examples. The Java Generics allows us to create a single class, interface, and method that can be used with different types of data (objects). This helps us to reuse our code. Note: Generics does… Continue reading Java Generics

In this article, we will learn about Java lambda expression and the use of lambda expression with functional interfaces, generic functional interface, and stream API with the help of examples. The lambda expression was introduced first time in Java 8. Its main objective to increase the expressive power of the language. But, before getting into… Continue reading Lambda Expressions

In this tutorial, we will learn about Java autoboxing and unboxing with the help of examples. Java Autoboxing – Primitive Type to Wrapper Object In autoboxing, the Java compiler automatically converts primitive types into their corresponding wrapper class objects. For example, Autoboxing has a great advantage while working with Java collections. Example 1: Java Autoboxing Output In… Continue reading Auto boxing and unboxing

In this tutorial, we will learn about the Java Type Casting and its types with the help of examples. Before you learn about Java Type Casting, make sure you know about Java Data Types. Type Casting The process of converting the value of one data type (int, float, double, etc.) to another data type is known as typecasting. In… Continue reading Type Casting
