I want to see arduino code output in java by using jssc library but this error pops up, but when i open serial viewer it says error COM3 busy

CODE:

import jssc.SerialPort;

import jssc.SerialPortEvent;

import jssc.SerialPortException;

import jssc.SerialPortList;


public class Arduino {
    

    public void connect(String portname) {
    
        
        SerialPort port = new SerialPort(portname);
        
        try {
            port.openPort();
            
            port.setParams(
                    
                    SerialPort.BAUDRATE_9600,
                    SerialPort.DATABITS_8,
                    SerialPort.STOPBITS_1,
                    SerialPort.PARITY_NONE
                    );
            port.addEventListener((SerialPortEvent event)->{
                
                if(event.isRXCHAR()) {
                    
                    try {
                        String s = port.readString();
                        System.out.print(s);
                    } catch (SerialPortException e) {
                    
                        e.printStackTrace();
                    }
                    
                }
                
            });
            
            
        } catch (SerialPortException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        
    }

    public static void main(String[] args) {
        // we need to array of string that hold all the ports
        String portlist[] = SerialPortList.getPortNames();
        
        for(int i =0; i<portlist.length;i++) {
            System.out.println(portlist[i]);
        }
        Arduino obj = new Arduino();
        obj.connect(portlist[0]);
        
        

    }

}
