  This is a start. Not sure if this is what you wanted.

  import javax.swing.JOptionPane;

  public class Temperature {
  public static void main(String[] args) {
  String []cities = new String[5];
  double [][]temps = new double[cities.length][7];

  // Fill the data arrays
  for (int i = 0; i < cities.length; i++) {
  String city = JOptionPane.showInputDialog(“Enter city name “);
  cities[i] = city;

  for (int j = 0; j < temps[0].length; j++) {
  String sTemp = JOptionPane.showInputDialog(“Temperature in ” + city + ” on day ” + (j+1) + “:”);
  temps[i][j] = Double.parseDouble(sTemp);
  }
  }

  // Calculate and print averages
  for (int i = 0; i < cities.length; i++) {
  String city = cities[i];
  double sum = 0;
  for (int j = 0; j < temps[0].length; j++) {
  sum += temps[i][j];
  }
  System.out.println(“City: ” + city + ” had an average temperature of ” + (sum/7.0));
  }
  }
  }
