How to create an object of a class where the constructor takes arguments as objects of other classes-CodePudding

I am a beginner in java. I recently came across this situation.

Suppose we have a class C.

public class C {
    C(A a, B b) {
    this.a = a;
    this.b = b;
    }
  A a;
  B b;

 ....

  }

Where a, b are objects of different classes.

public class A {
 ....
  }

public class B {
 ....
  }

So how do I create an object of type C ?

CodePudding user response：

You will need an instance of A and B to pass into the constructor of C. Something like this, assuming A and B have empty constructors:

A aObj = new A();
B bObj = new B();
C cObj = new C(aObj, bObj);

The cObj object's a and b fields will be references to the aObj and bObj instances that are constructed and passed in.
