问一个弱智，而又基础的问题！关于String的！

public static void main(String[] args){
    String a = "1";
    String b = "1";
    System.out.println("a == a -> " + a == a);
    System.out.println("a == b -> " + a == b);
    System.out.println(a.equals(b));
    System.out.println(a.hashCode() == b.hashCode());
}

猜一猜运行结果！！！！

运行了一下,大惊,结果不是String的问题...这样写就符合逻辑了
[code="java"]
public static void main(String[] args){
String a = "1";
String b = "1";
System.out.println("a == a -> " + (a == a));
System.out.println("a == b -> " + (a == b));
System.out.println(a.equals(b));
System.out.println(a.hashCode() == b.hashCode());
}
