Solution:

import java.util.Scanner;

public class Lab_Q2 {

public static void main(String [] args)

{

Scanner input = new Scanner(System.in);

double [][] sales = new double [3][5];

double [] totalsales = new double [3];

int i=0;

int j=0;

double average=0;

for(i=0; i<3; i++)

{

System.out.println("Employee "+(i+1));

for(j=0; j<5; j++)

{

System.out.print("Day "+(j+1)+": $");

sales[i][j] = input.nextDouble();

}

System.out.print(" ");

}

getTotalSales(sales,totalsales);

for(i=0 ;i<3; i++)

{

System.out.println("Employee "+(i+1)+" total sales :"+totalsales[i]);

}

findHighest(totalsales); //you misses this statement to print highest sale

System.out.println("Total collection of sales for this week:$"+(totalsales[0]+totalsales[1]+totalsales[2]));//you also //missed this to //print total collection

average=getAverage(sales);

System.out.println("Average sales for this week: $ "+average);

}

public static void getTotalSales(double [][] sales, double [] totalsales)

{

int i=0;

int j=0;

for(i=0; i<3; i++)

{

for(j=0; j<5; j++) //your were using 'i' in this loop as well

{

totalsales[i]+=sales[i][j];

}

}

}

public static int findHighest(double [] totalsales)

{

int highest=0;

if(totalsales[0]>totalsales[1])

System.out.println("Highest sales Employee 1");

else if(totalsales[1]>totalsales[0])

System.out.println("Highest sales Employee 2");

else if(totalsales[2]>totalsales[1])

System.out.println("Highest sales Employee 3");

else if(totalsales[1]>totalsales[2])

System.out.println("Highest sales Employee 2");

else if(totalsales[2]>totalsales[0])

System.out.println("Highest sales Employee 3");

else if(totalsales[0]>totalsales[2])

System.out.println("Highest sales Employee 1");

else

{

}

return highest;

}

public static double getAverage(double[][] sales)

{

double average=0;

int i=0;

int j=0;

for(i=0; i<3; i++)

{

for(j=0; j<5; j++) //you assigned 'j' to intially 1 instead of 0

{

average+=sales[i][j];

}

}

average=average/3;

return average;

}

}
