Java 中包装类wrapped type之间以及和primitive type的比较

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Integer a = new Integer(1);
        Integer b = new Integer(1);
        int c=1;
        Integer e = 1;
        System.out.println("a==b:"+(a==b));
        System.out.println("a==c:"+(a==c));
        System.out.println("a==e:"+(a==e));
        System.out.println("c==e:"+(c==e));
    }
