Java Program to smallest among three numbers

Java Program to smallest among three numbers

In this tutorial, we discuss Java Program to the smallest among three numbers

In this program, we will discuss a simple concept of the program to find the smallest number among three numbers in the Java programming language.

In this topic, we learn how to find the smallest number from given three numbers using if statements.

Find smallest among integer numbers

Program 1

import java.util.Scanner;
class Small_Three1{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
System.out.print("Enter the first number: ");
int num1=scan.nextInt();//get input from user for num1
System.out.print("Enter the second number: ");
int num2=scan.nextInt();//get input from user for num2
System.out.print("Enter the third number: ");
int num3=scan.nextInt();//get input from user for num3

if(num1<=num2 && num1<=num3){
    System.out.println("\n The Smallest number is: "+num1);
}
if(num2<=num1 && num2<=num3){
    System.out.println("\n The Smallest number is: "+num2);
}
if(num3<=num1 && num3<=num2){
    System.out.println("\n The Smallest number is: "+num3);
}
}
}

When the above code is compiled and executed, it produces the following results

Enter the first number: 56
Enter the second number: 23
Enter the tird number: 87

The Smallest number is 23

 

Find smallest among float numbers

Program 2

In this topic, we learn how to find the smallest number from given three float numbers using if statements.

import java.util.Scanner;
class Float_Small{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
System.out.print("Enter the first number: ");
float num1=scan.nextFloat();//get input from user for num1
System.out.print("Enter the second number: ");
float num2=scan.nextFloat();//get input from user for num2
System.out.print("Enter the third number: ");
float num3=scan.nextFloat();//get input from user for num3
if(num1<=num2 && num1<=num3){
    System.out.println("\n The Smallest number is "+num1);
}
if(num2<=num1 && num2<=num3){
    System.out.println("\n The Smallest number is "+num2);
}
if(num3<=num1 && num3<=num2){
    System.out.println("\n The Smallest number is "+num3);
}
}
}

When the above code is compiled and executed, it produces the following results

Enter the first number: 5.7
Enter the second number:2.3
Enter the third number: 8.7

The Smallest number is 2.3
