# Java Program To Find Greater Number. Among Given Three Number

Problem :- Write a C Program for find a greatest number among given three number .ex-you have to given three number ,number may be Integer, Float, Double You Task is to find a Greatest number Input given by User

Logic :- To solve this problem we need to compare all three numbers each other .for better explanation we need three number assume that numbers are 17 ,45 ,56

Step 1 :- First We Compare 17 to 45 and 56 if it is greatest then we can say that 17 is greatest else we go to next step

Step 2:- Then we compare 45 to 56 and 17  if it is greatest then we can say that 45 is greatest else we go to next step

Step 3:- Then we compare 56 to 45 and 17  if it is greatest then we can say that 56 is greatest else we go to next step (Special Case)

Step 4:- This is the last case if all numbers are same or equal then it will print a message that
" All INPUT ARE EQUAL "

num3=scan.nextInt();

if(num1>=num2 && num1>=num3)
{
System.out.println("Greatest Number Is : "+num1);
}
else if(num2>=num1 && num2>=num3)
{
System.out.println("Greatest Number Is : "+num2);
}
if(num3>=num1 && num3>=num2)
{
System.out.println("Greatest Number Is : "+num3);
}
}

}

Method 2:-Find Greatest Using Ternary Operator
