Using reflection we can see\access private data or private method of a class
u can try the below code and will easily see the desired result :-

import java.lang.reflect.Field;
class SimpleKeyPair {
private String privateKey = "India"; // private field
}
public class PrivateMemberAccessTest {
public static void main(String[] args) throws Exception {
SimpleKeyPair keyPair = new SimpleKeyPair();
Class c = keyPair.getClass();

// get the reflected object
Field field = c.getDeclaredField("privateKey");
// set accessible true
field.setAccessible(true);
System.out.println("Value of privateKey: " + field.get(keyPair)); // prints "Tokyo"
// modify the member varaible
field.set(keyPair, "Bharat");
System.out.println("Value of privateKey: " + field.get(keyPair)); // prints "Berlin"
}
}
