Can anyone help me put this code into seperate methods?

public static void Main(String[] args) {
		String num1String = JOptionPane.showInputDialog(null, "Please enter your first number");
		String num2String = JOptionPane.showInputDialog(null,"Please enter your second number");
		String num3String = JOptionPane.showInputDialog(null, "Please enter your third number");
		Double num1 =
		Double num2 =
		Double num3 = 
		JOptionPane.showMessageDialog(null, "The numbers you entered are: " + num1String + "," + num2String + ","  + num3String);
		double getSum = num1 + num2 + num3;
		if (getSum > 100)
			JOptionPane.showMessageDialog(null, "values have exceeded a sum of 100");
		JOptionPane.showMessageDialog(null, "The sum is " + getSum);
		double getAverage = num1 + num2 + num3 / 3;
		JOptionPane.showMessageDialog(null, "The average of your numbers is " + getAverage);

Methods do specific things. What are the "things" the posted code does? If you can say this code does this and that code does that, that would be a natural splitting point for creating some methods.
Create some method definitions with {} and cut and paste the code into the {}
Put a call to the method in the place where you cut the code from.
