Question

I have a basic doubt regarding object creation in java.Suppose i have two classes as follows

Class B{  
    public int value=100;  
}

Class A{  
    public B getB(){  
        return new B();  
    }  
    public void accessValue(){
        //accessing the value without storing object B
        System.out.println("value is :"+getB().value);

        //accessing the value by storing object B in variable b       
        B b=getB();
        System.out.println("value is :"+b.value);

   }  
}

My question is,does storing the object and accessing the value make any difference in terms of memory or both are same?

Answer 1

They are both equivalent, since you are instantiating B both times. The first way is just a shorter version of the second.
