    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:
    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;
    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.
