I am trying to find out why my program do not compute averages correct. It does all the other mathematical function correct but not averaging. Can you tell me where I went wrong with my code.

//Program: NumbersGame.java
//Creating java program to find sum, difference, product and averageString dataString; // input string



import javax.swing.JOptionPane;
public class Main_Class {

	// Numbers Game, a program that prompts the user for two integers and then displays their
	// Sum, Difference,Product and Average.
	public static void main(String[] args) {
	
	
	//Obtain numerical input and calculate results
	//strings entered by user
	String firstInput; 
	String secondInput;
	int input1;
	int input2;
	int sum;
	int difference;
	int product;
	int average;
	
	//read first input as string
	firstInput = JOptionPane.showInputDialog("Enter first integer");
	
	//read second input as string
	secondInput = JOptionPane.showInputDialog("Enter second inter");
	//converting inputs from string to integers
	input1 = Integer.parseInt (firstInput);
	input2 = Integer.parseInt(secondInput);
	//Perform calculations
	sum = input1 + input2;
	difference = input1 - input2;
	product = input1 * input2;
	average = input1 + input2 / 2;
	
	//display the results
	JOptionPane.showMessageDialog(null,"sum = " + sum,
			"Results",JOptionPane.PLAIN_MESSAGE);
	
	JOptionPane.showMessageDialog(null,"differnce = " + difference,
			"Results",JOptionPane.PLAIN_MESSAGE);
	JOptionPane.showMessageDialog(null,"product = " + product,
			"Results",JOptionPane.PLAIN_MESSAGE);
	
	JOptionPane.showMessageDialog(null,"average = " + average,
			"Results",JOptionPane.PLAIN_MESSAGE);
	System.exit(0);
	
	
	
	
	



		

	}

Run some tests and show us the results. Like Input1=10, Input2=12, and the resulting average is... It might be that you need to do the addition first and then the division.

as you may be familiar from math lessons, the division operator is executed before the plus operator.
so in your calculation here:

average = input1 + input2 / 2; 

you first divide input2 by 2, and then add input1.
you should change it like so:

average = (input1 + input2) / 2; 

this way, first you perform the addition of input1 and input2, and then dividing by 2.
