weatherfan.java

一些很简单的JAVA代码,一些人可以用上的

public class WeatherFan {
   public static void main(String[] args) {
      float[][] temperature = new float[10][365]; // Temperature array

      // Generate random temperatures
      for(int i = 0; i < temperature.length; i++) {
         for(int j = 0; j < temperature[i].length; j++) {
            temperature[i][j] = (float)(45.0*Math.random() - 10.0);
        }
      }

      // Calculate the average per location
      for(int i = 0; i < temperature.length; i++) {
         float average = 0.0f;     // Place to store the average

         for(int j = 0; j < temperature[i].length; j++) {
            average += temperature[i][j];
         }
         // Output the average temperature for the current location
         System.out.println("Average temperature at location "
                + (i+1) + " = " + average/(float)temperature[i].length);
      }
   }
}
