函数 --additem() 有 Integer 作为参数,但我不想传递所有整数。我需要发送一个然后调用其他函数。

public void readfile(String fileName) throws FileNotFoundException, IOException  {              
            File file = new File(fileName);
            FileInputStream fstream = new FileInputStream(file);
            // use DataInputStream to read binary NOT text
            // DataInputStream in = new DataInputStream(fstream);
            BufferedReader br = new BufferedReader(new InputStreamReader(fstream));            
            Scanner file2  = new Scanner(br);    

            while(file2.hasNext()){     
                String str = file2.nextLine();
                String[] spl= str.split(" ");               
                datas12.add(str);                       
                //System.out.println(str);          
                for(String line : spl) {                    
                    //System.out.println(datas12);                  
                    vs = Integer.parseInt(line);                
                    cb.addItem(vs); //Its adding all integers from vs.
                }                   
            }
}
