字符串valueof（char []）和新字符串（char []）之间的区别

Question

The output for following print statement is same, is there any internal difference which is safe as per Privacy Violation: Heap Inspection

char[] ch ={'p','a','s','s','w','o','r','d'};

System.out.println(String.valueOf(ch));

System.out.println(new String(ch));

Answer 1

There is no difference

valueOf is static factory method which calls String constructor

Answer 2

There is no real difference because internal implementation of valueOf is the following:

public static String valueOf(char data[]) {
    return new String(data);
}

As you can see it calls directly new String(data)
