JavaScript（13）
利用原生JSON对象，将对象转为字符串
var jsObj = {};
jsObj.testArray = [1,2,3,4,5];
jsObj.name = 'CSS3';
jsObj.date = '8 May, 2011';
var str = JSON.stringify(jsObj);
alert(str);
从JSON字符串转为对象
var jsObj = {};
jsObj.testArray = [1,2,3,4,5];
jsObj.name = 'CSS3';
jsObj.date = '8 May, 2011';
var str = JSON.stringify(jsObj);
var str1 = JSON.parse(str);
alert(str1);

1.&&重写Student类中的toString()和equals()方法；
2.写类Animal,Dog,Cat,Test,Dog和Cat继承Animal，Animal有属性name,Dog有属性color,Cat有weight属性，Test中有一个方法public void function(Animal a),调用该方法，首先输出传入对象的name,然后判断传入的是Dog还是Cat，并输出其自身特有的属性
