Today's programming do for a beginner is to write a Java programme to receive got input from the user as well as notice out maximum as well as minimum release 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 utilization java.lang.Math shape to perform about mathematical functioning e.g. max, 2nd or average. You tin sack utilization 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 sack overstep System.in, which is InputStream for Eclipse console, or dominance prompt, depending upon what you lot are using. This shape every bit good helps you lot to convert user input into requiring information type e.g. if a user enters numbers as well as then you lot must convert as well as then into int information type as well as shop them into int variable every bit shown inwards our example. You tin sack utilization nextInt() method to read user input every bit Integer.
Similarly, you lot tin sack utilization nextLine() to read user input every bit String. There are other methods available to read a float, double, or boolean from the dominance prompt. Once you lot got both the numbers, it simply matters of using relational operator less than as well as greater than to notice smaller as well as larger number, every bit shown inwards the next the example.
After that you lot tin sack Math.max() to notice the maximum of ii numbers, it should last same every bit your before result. Similarly, nosotros volition enquire User to operate inwards the release in i lawsuit again as well as volition display a minimum of two.
I every bit good propose you lot to read Head First Java 2nd Edition book, if you lot receive got simply started learning Java. It is i of the best books to larn Java inwards quick time.
That's all most how to calculate maximum as well as minimum of ii numbers inwards Java. In this tutorial, you lot receive got learned how to acquire input from the user, how to utilization a relational operator to compare ii numbers, as well as how to utilization java.lang.Math shape to perform mutual mathematical functioning e.g. finding maximum as well as minimum of ii numbers. If you lot receive got started learning Java inwards schoolhouse or whatever preparation center, I propose you lot to expire on a re-create of Head First Java or Core Java Volume 1 past times Cay S. Horstmann for your ain reference, those are ii nifty Java books for beginners.

Maximum as well as Minimum Example inwards Java
Our instance programme has ii parts. In the starting fourth dimension part, nosotros receive got input from a user, uses if block as well as relational operator to notice maximum value as well as farther used Math.max() method for the same purpose. In the 2nd component of the program, nosotros receive got asked the user to operate inwards ii to a greater extent than numbers as well as and then nosotros utilization less than the operator as well as if block to notice smaller of two. After that, nosotros receive got used Math.min() business office to calculate minimum release again. If your programme is right as well as then both output should last same.I every bit good propose you lot to read Head First Java 2nd Edition book, if you lot receive got simply 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 programme to calculate as well as impress maximum as well as minimum of ii numbers entered past times the user inwards dominance prompt. You tin sack run this programme from Eclipse IDE past times simply re-create pasting later on creating a Java projection as well as selecting it. Eclipse volition automatically do a origin file alongside the same advert every bit the populace shape as well as set it right package. Alternatively, you lot tin sack every bit good run this programme from the dominance prompt past times next steps given here.
import java.util.Scanner; import java.util.concurrent.Semaphore; import java.util.concurrent.locks.Condition; import java.util.concurrent.locks.Lock; import java.util.concurrent.locks.ReentrantLock; /** * * Java programme to calculate Maximum as well as minimum of ii numbers entered past times user inwards console. * * @author Javin Paul */ public class MaxMinExerciseInJava { public static void main(String args[]) throws InterruptedException { Scanner scnr = new Scanner(System.in); // Calculating Maximum ii numbers inwards Java System.out.println("Please operate inwards ii numbers to notice maximum of two"); int a = scnr.nextInt(); int b = scnr.nextInt(); if (a > b) { System.out.printf("Between %d as well as %d, maximum is %d %n", a, b, a); } else { System.out.printf("Between %d as well as %d, maximum release is %d %n", a, b, b); } int max = Math.max(a, b); System.out.printf("Maximum value of %d as well as %d using Math.max() is %d %n", a, b, max); // Calculating Minimum betwixt ii numbers inwards Java System.out.println("Please operate inwards ii numbers to notice minimum of two"); int x = scnr.nextInt(); int y = scnr.nextInt(); if (x < y) { System.out.printf("Between %d as well as %d, Minimum Number is %d %n", x, y, x); } else { System.out.printf("Between %d as well as %d, Minimum is %d %n", x, y, y); } int 2nd = Math.min(x, y); System.out.printf("Maximum value of %d as well as %d using Math.min() is %d %n", x, y, min); } } Output Please operate inwards ii numbers to notice maximum of ii 10 11 Between 10 as well as 11, maximum release is 11 Maximum value of 10 as well as 11 using Math.max() is 11 Please operate inwards ii numbers to notice minimum of ii 45 32 Between 45 as well as 32, Minimum is 32 Maximum value of 45 as well as 32 using Math.min() is 32
That's all most how to calculate maximum as well as minimum of ii numbers inwards Java.
