java：<创建一个MyInteger类>

设计名为MyInteger的类，它包括：
一个名为value的int型数据域，存储这个对象表示的int值。
一个为指定的int值创建的MyInteger对象的构造方法。
一个返回int的get方法。
如果值分别为偶数，奇数或素数，那么isEven（）、isOdd（）、isPrime（）方法都会返回true。
如果指定值分别为偶数，奇数或素数，那么isEven（int）、isOdd（int）、isPrime（int）方法都会返回true。
如果指定值分别为偶数，奇数或素数，那么isEven（MyInteger）、isOdd（MyInteger）、isPrime（MyInteger）方法都会返回true。
如果该对象的值与指定的值相等，那么equals（int）和equals（MyInteger）方法返回return。
静态方法parseInt（char[]）将数字字符构成的数组转换为一个int值。
静态方法parseInt（String）将一个字符串转换为一个int值。
编写用户程序测试该类中的所有方法。
