String constant pool and heap

[Charles Chikito]

The following examples are from Kathy's book

    // 1st example   
String s = "abc";    // creates one String object and one ref var   
  
// 2nd example   
String s = new String("abc");    // creates two objects and one ref var  
 


 

Does JVM sets the String constant pool within the heap or separately?

Which one does the ref var refers to in the 2nd example? The String object in the heap?

Objects relatd to String constant pool is also created in the heap but SCP has references to them.
2nd example's ref var refers to the object created by "new String();" statement which is created in the heap.
