Help, I'm Confused

Write a program named Median.java that asks the user for three integers and outputs the median.
I have to do this using if else statements. It seems really easy, but I can't figure it out. Help!

Here's my code:
Code:
import java.util.*;

public class Median {

	public static void main(String[] args) {
	
		Scanner console = new Scanner(System.in);
		
		System.out.println("Please enter number 1");
		int max = console.nextInt();
		int min = max;
		int median = min;
		
		for (int i=2; i <= 3; i++) {
			System.out.println("Please enter number "+i);
			int enteredNumber = console.nextInt();
			if (enteredNumber > max) {
				max = enteredNumber;
			}
			else {
				enteredNumber = median;
			}
			if (enteredNumber < min) {
				min = enteredNumber;
			}
			else {
				enteredNumber = median;
			}
		}
		System.out.println("The median is: "+median);
	}
}
When I run this it just gives me back the first number I entered.

The logic is half right, but you are overwriting the enteredNumber with that of the median which is backwards. Its easier than this though, with only 3 numbers:
PHP Code:
if (enteredNumber max)
{
    
median max;
    
max enteredNumber;
}
else if (
enteredNumber min)
{
    
median min;
    
min enteredNumber;
}
else
{
    
median enteredNumber;

If you can't use if/elseif, then the logic of if/elseif/else is identical to if/else(if/else).

Also, in the future please select a title that better describes the issue you are having.
