Thread: Array Homework assignment

I was given a homework assignment to create a program to convert money in accounts from usd to yen. With the code given to us, this is what I have came up with so far:

import java.util.*;
 
class DollarToYen
{
  public static final int MAX_DEPOSITS = 100;
  public static final float DOLLAR_TO_YEN = 0.098f;
 
  // read number of Dollars in each  account from the keyboard
  void readDollars(float[] dollars, int count )
  {
    Scanner kb = new Scanner(System.in);
    for(int j = 0; j < count; j++)
    {
      System.out.print("Enter the deposit amount(dollars) : $");
               j  = kb.nextInt();
    }
  }
 
  // Convert Dollars to Yen
  void dollarsToYen(float dollars[],float yen[],int count)
  {
  //  for (int j = 0; j < count; j++ )
    //	/DOLLAR_TO_YEN;
  }
 
  // Display the amount in each account in both Dollars and Yen
  void displayData(float dollars[],float yen[],int count )
  {
    for(int j = 0; j < count; j++ )
    {
      System.out.println("\nAccount ["+(j+1)+"] : ");
      System.out.println("\t"+dollars[j]+" dollars");
      System.out.println("\t"+yen[j]+" yen");
    }
    System.out.println();
  }
 
  public static void main(String[] args)
  {
	    int num;               // Actual number of  deposits
	    float[] dollars = new float[MAX_DEPOSITS];    // Dollars 
	    float[] yen = new float[MAX_DEPOSITS];      // Yen 
 
	    Scanner kb = new Scanner(System.in);
	    DollarToYen deposits = new DollarToYen();
 
	    // Prompt the user for the number of deposits
	    System.out.print("Enter the number of deposits: ");
	    num = kb.nextInt();
 
	    // Read the amount in each deposit
	    deposits.readDollars( );
 
	    // Convert Dollars to Yen.
	    deposits.dollarsToYen( );
 
	    // Display the amount in each deposit
	    deposits.displayData( );
	  }
	}

I cannot figure out how to get it to work correctly. Any help would be greatly appreciated.

lich0802 A few tips only: first of all you defined your methods with attributes but you dont use the same signature of your methods in main. Additional you dont need all of those attributes. for example in displayData method. Finally use nextFloat instead of nextInt.
