Java constructors initialize objects when they are created. A constructor has the same name as its class and has no explicit return type. There are two types of constructors: a no argument constructor that does not accept any parameters and initializes fields to default values, and a parameterized constructor that accepts parameters and initializes fields to the values passed in.

2. Java Constructor Basics
● A constructor initializes an object when it is created.
● It has the same name as its class.
● Constructors have no explicit return type.
● Java automatically provides a default constructor if there
is no explicit constructor.

3. Java Constructor Types - No Argument Constructor
● It doesn't accept any parameter.
● Syntax:
Public class TestClass {
Int num;
TestClass() {
num = 10;
}
}

4. Java Constructor Types - Parameterized Constructor
● It accepts parameters.
● Syntax:
class TestClass {
int x;
TestClass(int i) {
x = i;
}
}
