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
- Start the program
- Read/input two integers
- Check if both the integers are equal, print “Equal” if true.
- Check if number1>number2, print number1 if true.
- 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:
50 is largest
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");
}
}
Output:
31 is greater
