Java-Java String 常量池

Question

常量池的定义是否是不同的类创建不同的常量池，
但是

public class World
{   
    public static void main(String[] args)
    {   
        Conner a = new Conner();
        String s1="abc";
        String s2=a.s1;
        
        System.out.println(s2 == s1);
    }
}

public class Conner
{
    String s1="abc";
    public static String s()
    {
        return "abc";
    }
}

Answer 1

/**
* Initializes a newly created {@code String} object so that it represents
* the same sequence of characters as the argument; in other words, the
* newly created string is a copy of the argument string. Unless an
* explicit copy of {@code original} is needed, use of this constructor is
* unnecessary since Strings are immutable.
*
* @param original
* A {@code String}
*/
public String(String original) {
this.value = original.value;
this.hash = original.hash;
}

这是string的源码,可以看出是先new一个对象后,拷贝值到数组中,不同的对象,所以地址也不一样
