考虑以下代码:

String first = "abc"; 
String second = new String("abc");

使用new关键字时,Java会abc String再次创建吗？这会存储在常规堆还是String池中？多少人String在将s结尾String池？

可能重复:
Java字符串:"String s = new String("silly");"

如果我写

String s= new String("how many object b created by this method ");

与这样做相比,将创建多少个参考对象和对象:

Sting s1="Is this method is good as compare to upper";
