访问String Constant Pool Java!

public class StringLiterals {
    public static void main(String[] args) {
        String s1="This is ";
        s1=s1+"my book";
        String s2="This is my book";
        System.out.println(s1==s2);

    }
}

O/P:假

期待O/P:是的

interface A {
}

public class B {
    public static void main(String a[]) {
        Class c = Class.forName("A");
        System.out.println(c.isInterface());//false
        Class c1 = A.class;
        System.out.println(c1.isInterface());//true
    }
}

o/p:false true

期待o/p:真实

我不想知道这两者的区别:Class.forName("A")和A.class非常感谢.
