New to Java! We have to create a "sales" 2D array and initialize it with 100.00. Then we have to up the 3rd quarter by 500.00 and then lower the 4th quarter by 50.00. I know there's something simple I'm missing, but I can't quite figure it out. Any help will be greatly appreciated! Thanks!
This is the code:
public class Array2D
{
public static void main(String args[])
{
double sales[][] = new double[5][4] ;
for (int row = 0; row <sales.length; row++)
{
for (int column = 0; column < sales[row].length; column++)
{
sales[row][column] = 100.00 ;
System.out.print(sales[row][column] + " ") ;
}
System.out.println();
}
System.out.println("**************************") ;
quarterThree(sales) ;
quarterFour(sales) ;
}
public static void quarterThree(double sales[][])
{
for (int row = 0; row < sales.length; row++)
{
for (int column = 0; column < sales[row].length; column++)
{
sales[row][2] = sales[row][2] + 500.00 ;
System.out.print(sales[row][column] + " ") ;
}
System.out.println() ;
}
System.out.println("**************************") ;
}
public static void quarterFour(double sales[][])
{
for (int row = 0; row < sales.length; row++)
{
for (int column = 0; column < sales[row].length; column++)
{
sales[row][3] = sales[row][3] - 50.00 ;
System.out.print(sales[row][column] + " ") ;
}
System.out.println() ;
}
}
}//end classAnd this is the output:
