Today's programming practise for a beginner is to write a Java plan to receive got input from the user as well as uncovering out maximum as well as minimum disclose as well as impress them into the console. The role of this article is to learn you lot how to acquire input from a user inwards Java as well as how to usage java.lang.Math cast to perform approximately mathematical functioning e.g. max, 2d or average. You tin usage Scanner class, added inwards Java 1.5 to read user input from the console. Scanner needs an InputStream to read information as well as because you lot are reading from the console, you lot tin function past times System.in, which is InputStream for Eclipse console, or ascendancy prompt, depending upon what you lot are using. This cast too helps you lot to convert user input into requiring information type e.g. if a user enters numbers hence you lot must convert hence into int information type as well as shop them into int variable equally shown inwards our example. You tin usage nextInt() method to read user input equally Integer.
Similarly, you lot tin usage nextLine() to read user input equally String. There are other methods available to read a float, double, or boolean from the ascendancy prompt. Once you lot got both the numbers, it only matters of using relational operator less than as well as greater than to uncovering smaller as well as larger number, equally shown inwards the next the example.
After that you lot tin Math.max() to uncovering the maximum of 2 numbers, it should last same equally your before result. Similarly, nosotros volition enquire User to function inwards the disclose i time again as well as volition display a minimum of two.
I too propose you lot to read Head First Java 2nd Edition book, if you lot receive got only started learning Java. It is i of the best books to larn Java inwards quick time.
That's all virtually how to calculate maximum as well as minimum of 2 numbers inwards Java. In this tutorial, you lot receive got learned how to acquire input from the user, how to usage a relational operator to compare 2 numbers, as well as how to usage java.lang.Math cast to perform mutual mathematical functioning e.g. finding maximum as well as minimum of 2 numbers. If you lot receive got started learning Java inwards schoolhouse or whatever preparation center, I propose you lot to boot the bucket along a re-create of Head First Java or Core Java Volume 1 past times Cay S. Horstmann for your ain reference, those are 2 peachy Java books for beginners.

Maximum as well as Minimum Example inwards Java
Our instance plan has 2 parts. In the kickoff part, nosotros receive got input from a user, uses if block as well as relational operator to uncovering maximum value as well as farther used Math.max() method for the same purpose. In the 2d component division of the program, nosotros receive got asked the user to function inwards 2 to a greater extent than numbers as well as hence nosotros usage less than the operator as well as if block to uncovering smaller of two. After that, nosotros receive got used Math.min() component division to calculate minimum disclose again. If your plan is right hence both output should last same.I too propose you lot to read Head First Java 2nd Edition book, if you lot receive got only started learning Java. It is i of the best books to larn Java inwards quick time.
Java Program to calculate Maximum as well as Minimum of Numbers
Here is our sample Java plan to calculate as well as impress maximum as well as minimum of 2 numbers entered past times the user inwards ascendancy prompt. You tin run this plan from Eclipse IDE past times only re-create pasting later creating a Java projection as well as selecting it. Eclipse volition automatically do a rootage file amongst the same refer equally the populace cast as well as lay it right package. Alternatively, you lot tin too run this plan from the ascendancy prompt past times next steps given here.

That's all virtually how to calculate maximum as well as minimum of 2 numbers inwards Java. In this tutorial, you lot receive got learned how to acquire input from the user, how to usage a relational operator to compare 2 numbers, as well as how to usage java.lang.Math cast to perform mutual mathematical functioning e.g. finding maximum as well as minimum of 2 numbers.
