Find the Greatest of the Two Numbers in Java

Here, we will learn the basic java program to find the greatest of the two numbers.

Problem :

simple example of problem :

 Input :

Enter the first number: 8
Enter the second number: 15

 Output :

The greater number is: 15

Explanation:

In this example, the program compares the two numbers (8 and 15) and determines that 15 is greater, so it prints “The greater number is: 15”.

Solution :

there are few ways to find the largest or greatest of two numbers in java:

• Method 1: Using if-else Statements
• Method 2: Using Ternary Operator
• Method 3: Using inbuilt math.max() method

Approach 1 : Using if-else Statements

In this method we will use if-else statements to compare the two numbers  and print the greatest.

Algorithm

1. Start the program
2. Read/input two integers
3. Check if both the integers are equal, print “Equal” if true.
4. Check if number1>number2, print number1 if true.
5. Check if number2>number1, print number2 if true.

Code:

// java program to find the largest of two numbers in java
public class Main
 {
   public static void main (String[]args)
   {

     int num1 = 70, num2 = 20;
     if (num1 == num2)
       System.out.println ("both are equal");
     else if (num1 > num2)
         System.out.println (num1 + " is greater");

     else
         System.out.println (num2 + " is greater");

   }
 }

Output:

70 is greater

Approach 2 : Using Ternary Operator:

In this method we’ll use the Ternary Operator and compare the two numbers to check for the greatest  or Largest among them.

Algorithm:

• Read/input two integers
• Check for the greatest among the two using Ternary Operator.

public class Main
{
  public static void main (String[]args)
  {
    int num1 = 50, num2 = 30, temp;

    if (num1 == num2)
      System.out.println ("Both are Equal\n");
    else
      {
    temp = num1 > num2 ? num1 : num2;
    System.out.println (temp + " is largest");
      }

  }
}

Output:

Approach 2 : Using inbuilt max Function:

In this method we’ll use the inbuilt math.max() method to get the greatest or Largest of the two integer inputs

public class Main {
    public static void main(String args[])
    {
        int num1 = 13, num2 = 31;
        if (num1 == num2)
            System.out.println("both are equal");
        else
            // prints the maximum of two numbers
            System.out.println(Math.max(num1, num2) + " is greater");
    }
}
