常量池的1.8测试

1.8的String.intern()好像有些变化，但是感觉和1.76没啥不同，难道是常量池引用那里有什么特别处理？

public class ConstantPool {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
         stest t=new stest();
         t.run();
    }


}
 class stest {
    private static final String s11="hello";
    private static final String s22="world";
    public static void run() {
        String s1="hello";
        String s0=new String("hello");
        String s01=new String("hello");
        String s2="world";
        String s3="helloworld";
        String s4=s11+s22;
        String s5=s1+"world";
        String s6=s5.intern();
        String s7="hello"+new String("world");
        System.out.println(s3==s4); //t
        System.out.println(s1==s0); //f
        System.out.println(s01==s0); //f
        System.out.println(s3==s5); //f
        System.out.println(s4==s5); //f
        System.out.println(s4==s6); //t
        System.out.println(s3==s7); //f
        System.out.println(s4==s7); //f
        System.out.println(s5==s7); //f
    }
}
