Java 字符串对象和存储

以下代码将创建多少个对象，它们将存储在何处

String s = "abc"; // line 1
String s1 = new String("abc"); // line 2
String str1 = new String("efg"); //line 3

供参考：

3个对象将被创建，1个在SCP中，2个在HEAP中。您最好猜一下是什么，为什么？搜索

创建了多少字符串

会产生很多类似的问题。@Deadpool请原谅，但我不说SCP是指“字符串常量池”吗？字符串池中不也会存储“efg”吗？

Total 3 objects will be created.    
Line 1 : Object will be created in string pool,
Line 2 : Object will be created in Heap,
Line 3 : Object will be created in Heap.

Reason is : 
a) By string literal : Java String literal is created by using double quotes like in line 1. It is always created in String pool,
b) By new keyword : Java String is created by using a keyword “new” like in line 2 and 3.  It is always created in Heap memory.
