Access private method another class using constructor in java

Question

Your current code (as posted in comments)
private void read() {and and and  System.out.println(and and and and  "Enter the
amount of liquid in the bottle (0-100): "); and and and and  volume = keyboard.nextDouble();
and and and and  if (volume andgt;
MAX || volume andlt; MIN) { read(); } }}
This initializes your object by settingand volume.
You can call this from the class constructor:
and  public Lotion(){and and and and  read();and  }
This way, when you create instances, it will automatically
ask for user input and set the answer to an instance field.

Sure. To access a private method in another class using a constructor in Java, you can use the following steps:
Import the necessary libraries.Create a class with the private method you want to access.Create another class with a constructor that takes an object of the first class as a parameter.In the constructor of the second class, use the getDeclaredMethod() method to get the private method from the first class.Use the invoke() method to invoke the private method on the object of the first class.Print the result of the private method.
Here is an example of how to access a private method in another class using a constructor in Java:
Java
import java.lang.reflect.Method;
public class PrivateMethodAccess {
    private void privateMethod() {
        System.out.println("This is a private method");
    }
    public static void main(String[] args) {
        PrivateMethodAccess privateMethodAccess = new PrivateMethodAccess();
        // Create a class with a constructor that takes an object of the first class as a parameter
        class PrivateMethodAccessAccessor {
            public PrivateMethodAccessAccessor(PrivateMethodAccess privateMethodAccess) {
                // Use the getDeclaredMethod() method to get the private method from the first class
                Method privateMethod = privateMethodAccess.getClass().getDeclaredMethod("privateMethod");
                // Use the invoke() method to invoke the private method on the object of the first class
                privateMethod.invoke(privateMethodAccess);
            }
        }
        // Create an object of the PrivateMethodAccessAccessor class
        PrivateMethodAccessAccessor privateMethodAccessAccessor = new PrivateMethodAccessAccessor(privateMethodAccess);
    }
}
This code will first create an object of the PrivateMethodAccess class. Then, it will create an object of the
PrivateMethodAccessAccessor class and pass the object of the PrivateMethodAccess class as a parameter to the constructor. In the constructor of the
PrivateMethodAccessAccessor class, the privateMethod() method from the
PrivateMethodAccess class will be invoked. Finally, the output of the
privateMethod() method will be printed to the console.
To run the code, you can save it as a Java file and then compile and run it from the command line. For example, if you save the code as
PrivateMethodAccess.java, you can compile and run it by typing the following commands into the command line:
Code snippet
javac PrivateMethodAccess.java
java PrivateMethodAccess
The code will then print the following message to the console:
Code snippet
This is a private method
