Java Math min() Function Example

Java Math min() is an inbuilt method that compares two numbers (can be of either int, float, double, or long type) and returns the minimum of two numbers.

Java Math min()

Java math.min() is an inbuilt function that returns a minimum of two numbers. The arguments are taken in int, float, double, and long, and if both parameters passed are negative, then a number with the higher magnitude is generated as a result.

Syntax

public static int min(int a, int b)
public static double min(double a, double b)
public static float min(float a, float b)
public static long min(long a, long b)

How to Install OpenJDK 11 on CentOS 8

What is OpenJDK?

OpenJDk or Open Java Development Kit is a free, open-source framework of the Java Platform, Standard Edition (or Java SE). It contains the virtual machine, the Java Class Library, and the Java compiler. The difference between the Oracle OpenJDK and Oracle JDK is that OpenJDK is a source code reference point for the open-source model. Simultaneously, the Oracle JDK is a continuation or advanced model of the OpenJDK, which is not open source and requires a license to use.

In this article, we will be installing OpenJDK on Centos 8.

Functional Interfaces in Java 8

Introduction

Functional interface is an interface that consists of one abstract method. These interface can show only one functionality. Beyond Java 8, _lambda expressions _can be used to represent the instance of a functional interface. Functional Interfaces can contain any number of default methods. Consumer, Predicate, Function, Unary Operator, Binary Operator are some of the examples of predefined functional interfaces.

Points to remember which are allowed and which are not allowed in a functional interface:

• In any functional interface, single abstract method is allowed.
• In a functional interface, more than one abstract method cannot exist.
• We can have more than one abstract method if we remove @FunctionalInterface  annotation, but that interface cannot be functional interface.

From functional interface if we remove @FunctionalInterface annotation, it must be valid. We use an annotation so that only single abstract method can be present. In functional interface we can provide implementations as the default methods inside interface.

Lambda Expression in Java 8

In this blog we will understand what is the lambda expression and why we need lambda expression and how we use lambda and about the functional interface.

What is Lambda Expression :

• It is an anonymous function.
• Not having name
• No return type and no modifiers.

Going Beyond Java 8: Local Variable Type Inference (var) - DZone Java

According to some surveys, such as JetBrains’s great survey, Java 8 is currently the most used version of Java, despite being a 2014 release.

What you are reading is one in a series of articles titled ‘Going beyond Java 8,’ inspired by the contents of my book, Java for Aliens. These articles will guide you step-by-step through the most important features introduced to the language, starting from version 9. The aim is to make you aware of how important it is to move forward from Java 8, explaining the enormous advantages that the latest versions of the language offer.

In this article, we will talk about the most important new feature introduced with Java 10. Officially called local variable type inference, this feature is better known as the **introduction of the word **var. Despite the complicated name, it is actually quite a simple feature to use. However, some observations need to be made before we can see the impact that the introduction of the word var has on other pre-existing characteristics.
