In this tutorial, we will discuss the concept of Java program:find the smallest of three numbers using the method.
In this post, we will learn how to find the smallest number among three numbers using a user-defined method in the Java programming language
In my previous post, I have explained the various approaches to find the smallest number of among three numbers in Java language
However, in this program, we embed the logic of the “find the smallest of three numbers” program in the method.
Here, I have explained how to find the smallest number from the given three number and how to embed this logic in the method.
Program 1
This program allows the user to enter three numbers and compare to select the smallest number using if-else-if statements
import java.util.Scanner; class SmallestNum2{ public static void main (String args[]){ Scanner scan=new Scanner(System.in); //create a scanner object for input System.out.print("Enter the first number\n"); int num1=scan.nextInt();//reads num1 from user System.out.print("Enter the second number\n"); int num2=scan.nextInt();;//reads num2 from user System.out.print("Enter the Third number\n"); int num3=scan.nextInt();;//reads num3 from user //calling the method findSmallest(num1,num2,num3); } static void findSmallest(int num1,int num2, int num3){//method definition if(num1<=num2 && num1<=num3){ System.out.println(num1+" is the smallest number"); } else if(num2<=num1 && num2<=num3){ System.out.println(num2+" is the smallest number"); } else{ System.out.println(num3+" is the smallest number"); } } }
When the above code is executed, it produces the following results
Enter the first number 45 Enter the second number 89 Enter the third number 23 23 is the smallest number
Program 1
This program allows the user to enter three numbers and compare to select the smallest number using nested-if statements
import java.util.Scanner; class SmallestNum3{ public static void main (String args[]){ Scanner scan=new Scanner(System.in); //create a scanner object for input System.out.print("Enter the first number\n"); int num1=scan.nextInt();//reads num1 from user System.out.print("Enter the second number\n"); int num2=scan.nextInt();;//reads num2 from user System.out.print("Enter the Third number\n"); int num3=scan.nextInt();;//reads num3 from user //calling the method findSmallest(num1,num2,num3); } static void findSmallest(int num1,int num2, int num3){//method definition if(num1<=num2){ if(num1<=num3) System.out.println(num1+" is the smallest number"); else System.out.println(num3+" is the smallest number"); } else{ if(num2<=num3) System.out.println(num2+" is the smallest number"); else System.out.println(num3+" is the smallest number"); } } }
When the above code is executed, it produces the following results
Enter the first number 79 Enter the second number 23 Enter the third number 56 23 is the smallest number
