how to pass parameters from a method to another which accepts to parameters?possible?

in this code, i would like to know how to pass the convertedWorkArray from the first method to the second one ??
N.B:
both methods belong to the same class
i dont want the method ( getsum) to receive any parameters from the (main), i just want to know how to set the (convertedworkarray) visible to the method (getsum)

Code:

---


 public  int []convertStrToInt()
            {
                    int [] [COLOR="Red"]convertedWorkArray[/COLOR] = new int [workarray.length];
                                       
                    for (int i=0;i<workarray.length;i++)
                            convertedWorkArray[i]=Integer.parseInt(workarray[i]);
                        System.out.println("Your array was converted into integers");
            return convertedWorkArray;
        }
   
 public int getSum()
    {
            int sum=0;
            for (int i=0 ; i<[COLOR="red"]convertedWorkArray[/COLOR].length ; i++)
                    sum+ = convertedWorkArray[i];
                    return sum;                             
    }

        public static void main (String [] args)
      {
          Op obj = new Op();
          Scanner read = new Scanner (System.in);     
          String scanchoice;
          int size, choice,value;
         
          do
          {
                    System.out.println("choose an operation: 1:+ 2:- 3:* 4:/");
              scanchoice = read.nextLine();
              choice = Integer.parseInt(scanchoice);
             
                  switch (choice)
                    {
                          case 1 : System.out.println("enter number of elements:");
                                      value=read.nextInt();
                                      obj.setsize(value);
                                      obj.initialize();
                                      obj.getnumofoperands();
                                      obj.[COLOR="Red"]convertStrToInt[/COLOR]();
                                      System.out.println("Thu Sum = "+obj.[COLOR="Red"]doSum());[/COLOR]
                                    /* pluseop(operand1,operand2);
                          case '2' : initialize();         
                                          subop(operand1,operand2);
                  case '3' : initialize();
                                  mulop(operand1,operand2);
                  case '4' : initialize();
                                  divop(operand1,operand2);*/
                    }// end switch
              } while(choice!=1 || choice!=2 || choice!=3 || choice!=4); // end do-while
             
      }  // end main   
} //end class

If you don't want to pass that array around as a parameter you could define it to be a member variable, so take out the definition from the method and stick it back in at the class level.

Mr. Jos,
do ou mean the following:
to define the convertedWorkArray outside the methods so that to be accessible by all member methods??

Code:

---


public class Op
{
        public  int arraysize;
        private double operand1, operand2;
        private int numofoperands;
       
    Scanner read=new Scanner(System.in);
        String scandata, scaninput;
        int scannumofoperands,scanoperandsindex;
        public  String [] workarray;
        public String [] dataarray;
[COLOR="Red"]        public int [] convertedWorkArray;[/COLOR]

method1
{
...
...
}

method2
{
...
...
}

 public  int []convertStrToInt()
            {
                    [COLOR="red"]convertedWorkArray [/COLOR]= new int [workarray.length];
                                       
                    for (int i=0;i<workarray.length;i++)
                            convertedWorkArray[i]=Integer.parseInt(workarray[i]);
                        System.out.println("Your array was converted into integers");
            return convertedWorkArray;
        }

public int getSum()
    {
            int sum=0;
            for (int i=0 ; i<[COLOR="red"]convertedWorkArray[/COLOR].length ; i++)
                    sum+ = convertedWorkArray[i];
                    return sum;                             
    }

Yep, that's what I mean but I'd personally go with the parameter passing way ...

kind regards,

Jos

is it what you meant by parameter passing to the the methods??
N.B: in the (main) i dont want the method (getSum) to accept any parameters,

Code:

---


int [] convertStrToInt ()
{
  String [] Convertedworkarray = new int [workarray.length];
                                       
                    for (int i=0;i<workarray.length;i++)
                            convertedWorkArray[i]=Integer.parseInt(workarray[i]);
                    System.out.println("Your array was converted into integers");
                          return convertedWorkArray
}

int getSum(String [] convertedworkarray)
{
    int sum=0;
            for (int i=0 ; i<convertedWorkArray.length ; i++)
                    sum+ = convertedWorkArray[i];
                    return sum;
}

So, do as I suggested and make that array a member variable; it'll be visible to each method and doesn't need to be passed in as a parameter.
