                Long a = (long) 1000;
        Long b = (long) 1000;
        long c = 1000;
        long d = 1000;
        System.out.println("a == b:" + (a == b));
        System.out.println("c == d:" + (c == d));
        System.out.println("a.equals(b):" + a.equals(b));

输出:

a == b:false
c == d:true
a.equals(b):true

Long是包装类型,是对象,要用equals方法做比较;

long是基本数据类型,可以直接通过“>”,“==”,“<”作比较
