default constructor in parameterized

No, if you define a parameterized constructor in a Java class, the compiler will not automatically create a default constructor for you.

A default constructor is a constructor with no parameters, and it is automatically generated by the compiler only if there are no constructors defined explicitly in the class. If you define any constructor, whether it’s parameterized or not, the compiler assumes that you have provided your own constructor logic and will not generate a default constructor.

Here’s an example to illustrate this:

```java
public class MyClass {
    private int value;

    // Parameterized constructor
    public MyClass(int value) {
        this.value = value;
    }

    public int getValue() {
        return value;
    }

    public static void main(String[] args) {
        // Attempt to create an instance of MyClass without a default constructor
        // This will result in a compilation error because there's no default constructor
        // MyClass obj = new MyClass(); 
    }
}
```

In this example, `MyClass` has a parameterized constructor that accepts an integer value. If you attempt to create an instance of `MyClass` without providing an integer value, such as `MyClass obj = new MyClass();`, it will result in a compilation error because there’s no default constructor available. You would need to provide an integer value to create an instance of `MyClass`.
