In this article, we will discuss the concept of Java program to Find Largest of three numbers
In this post, we are going to learn how to write a program to find largest number out of three numbers using different methods in Java program.
Code to find largest numbers
Code to find largest numbers using if statements
In this code, we will find largest number out of three numbers using if statements in Java language
Program 1
import java.util.Scanner;
class Large_Of_Three{
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
System.out.print("Enter the second number: ");
int num2=scan.nextInt();//get input from user
System.out.print("Enter the third number: ");
int num3=scan.nextInt();//get input from user
if(num1>=num2 && num1>=num3){
System.out.println("\n The largest number is: "+num1);
//Checking the num1 is largest
}
if(num2>=num1 && num2>=num3){
System.out.println("\n The largest number is: "+num2);
//Checking the num2 is largest
}
if(num3>=num1 && num3>=num2){
System.out.println("\n The largest number is: "+num3);
//Checking the num3 is largest
}
}
}
When the above code is executed, it produces the following result
Enter the first number: 1877 Enter the second number: 9877 Enter the third number:: 456 The largest number is: 9877
Code to find largest numbers using Array
In this code, we will find largest number out of three numbers using Array in Java language
Program 2
import java.util.Scanner;
class Large_Num_Array{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
System.out.print("Enter the number of elements in an array: ");
int max;
int n=scan.nextInt();//get input from user for array length
int arr[]=new int[n]; //declaring an array of n elements
//for loop takes input from user
for(int i=0; i<n; i++){
System.out.print("Enter the element "+(i+1)+": ");
arr[i]=scan.nextInt();//takes input from user for array
}
max=arr[0];
for(int i=0; i<n; i++){
if(max<arr[i]){
max=arr[i];
}
}
System.out.print("\nThe largest value is: "+max);
}//display result on the screen
}
When the above code is executed, it produces the following result
Enter the number of elements in an array:: 3 Enter the element 1: 9876 Enter the element 2: 6543 Enter the element 1: 4321 The largest value is: 9876
