Java

I am trying to create a program, which requires the person to Login first!
My code is as follows:

import comp102x.IO;
/*import java.awt.Toolkit;
import java.lang.*;
import java.awt.datatransfer.Clipboard;
import java.awt.datatransfer.StringSelection;*/
public class Main
{
    public void loginCheck()
    {
        String correctPassword = new String();
        correctPassword = "sanvar55";
        String password = new String();
        System.out.print("Enter Password:");
        password = IO.inputString();
        System.out.println(password);
        if(password=="sanvar55")
        {
            System.out.println("Correct Password");
            //CopyStringToClipboard(password);
        }
        else
        {
            System.out.println("Incorrect Password!");
        }
    }
    /*private static void CopyStringToClipboard(String input) 
    {
        String str = input;
        Toolkit toolkit = Toolkit.getDefaultToolkit();
        Clipboard clipboard = toolkit.getSystemClipboard();
        StringSelection strSel = new StringSelection(str);
        clipboard.setContents(strSel, null);
    }*/
}

What I have tried:

But on executing, I get the following output:

Enter Password:sanvar55
sanvar55
Incorrect Password!

I am not able to understand, why it is doing so?
