Question

********** PLEASE PROVIDE IN JAVA & NEW SET OF ALGORITHM

For this lab use the program at the bottom to sort an array using selection sort. Write a selection sort to report out the sorted low values: lowest to highest. Write another to report out the sorted high values – highest to lowest. Last but not least, the program should output all the values in the array AND then output the 2 requested sorted outputs.

-----> MY OLD PROGRAM BELOW

importjava.util.Scanner; // import Scanner

publicclassModule1B {
  
   publicstaticvoidmain(String[] args)
   {
       // declaring the temperatures array
      double[] maxTemp = newdouble[12]; // assigned 12
      double[] lowTemp = newdouble[12]; // assigned 12
      doubleavgHighTemp = 0; // initializing the average high temp to zero
      doubleavgLowTemp = 0; // initializing the avergae low temp to zero
      
      // Create a Scanner object
      Scanner input = newScanner(System.in);
       // Input temperatures one by one
      for(inti = 0; i < 12; i++)
      {
         System.out.print("Enter the highest temperature for month # "+ (i+1) + " : "); // Enter the temp for each high temp of the # month
         maxTemp[i] = Integer.parseInt(input.nextLine()); // Data of the months will enter the maxTemp array
         System.out.print("Please enter the lowest temperature for month # "+ (i+1) + " : "); // Enter the temp for each low temp of the # month
         lowTemp[i] = Integer.parseInt(input.nextLine()); // Data of the months will enter the lowTemp array
        System.out.println();
      }
      avgHighTemp = getAvgHighTemperature(maxTemp); // the average High temp is made up of the getAvgHighTemp method & max temp array
      avgLowTemp = getAvgLowTemperature(lowTemp); // the avgLowTemp is made up of the getAvgLowTemp method & low temp
      System.out.println("Average high temperature is: "+ (int)avgHighTemp); // Average will return as an integer
      System.out.println("Average low temperature is: "+ (int)avgLowTemp); // Average will return as an integer
      
   }
