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

[amrmb09]

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)

 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??

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,

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,

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.
