String str = new String("abc");
构造方法说明:java.lang.String.String(String original)
解释:Initializes a newly created
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
Strings are immutable.
构造方法说明:java.lang.String.String(String original)
解释:Initializes a newly created
Stringobject 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
originalis needed, use of this constructor is unnecessary since
Strings are immutable.
