    import java. util. Arrays;

    import java. util. Scanner;

    public class num1 {

    public static void main (String[] args) {

    Scanner in = new Scanner (System. in);

    int []monthlyRainfall = new int [12];

    System. out. println ("Enter rainfall for January");

    monthlyRainfall[0] = in. nextInt ();

    for (int i = 1; i
    System. out. println ("Enter rainfall for the next Month");

    monthlyRainfall[i] = in. nextInt ();

    }

    System. out. println ("The complete list is:");

    System. out. println (Arrays. toString (monthlyRainfall));

    //Calculating the total and average rainfall

    int totalRainfall = 0;

    for (int i=0; i
    totalRainfall+=monthlyRainfall[i];

    }

    System. out. println ("Total rainfall is " + totalRainfall);

    System. out. println ("Average rainfall is " + (totalRainfall/12));

    / / finding the lowest rainfall

    int min = monthlyRainfall[0];

    int minMnth = 0;

    for (int i=0; i
    if (min>monthlyRainfall[i]) {

    min = monthlyRainfall[i];

    minMnth = i+1;

    }

    }

    System. out. println ("The minimim rainfall is "+min);

    System. out. println ("The month with the minimum rainfall is "+minMnth);

    / / finding the highest rainfall

    int max = monthlyRainfall[0];

    int maxMnth = 0;

    for (int i=0; i
    if (max
    max = monthlyRainfall[i];

    maxMnth = i+1;

    }

    }

    System. out. println ("The maximum rainfall is "+max);

    System. out. println ("The month with the maximum rainfall is "+maxMnth);

    }

    }

    Explanation:

    Create an array to hold the list of monthly rainfall from january to December int []monthlyRainfall = new int [12]; Prompt user to enter the values for the monthly rainfall and fill up the array with the values using a for loop Print the populated List Use a for loop to calculate the Total rainfall by adding elements from index 0-11 Calculate the average rainfall totalrainfal/12 Using a for loop, find the maximum and minimum values in the array The index of the minimum value plus 1 Gives the month with the lowest rainfall The index of the maximum value + 1 gives the month with the highest value
