            <p><b><span class="article">3.2 操作符</span></b></p>
            <p class="article"> 　　本节教程描述了怎执行各种操作，比如算术和赋值操作。</p>
            <p class="article"> 　　一个操作符利用一个、两个或者三个运算对象来执行了一个函数。只需要一个运算对象的操作符称为单元运算符。例如++是一个单元操作符，它是对运算对象自增1。需要两个运算对象的操作符号称为双元操纵符。比如等于号（=）就是一个双元操作符，它指定右边的运算对象给左边的运算对象。最后，三元操作符需要三个运算对象。JAVA编程语言有一个三元运算符？：，它是一个简要的if-else语句。</p>
            <p class="article"> 　　单元操作符支持前缀或者后缀记号。前缀记号是指操作符出现在它的运算对象之前，例如： </p>
            <p class="article"> operator op //前缀记号</p>
            <p class="article"> 后缀记号是指运算对象出现在操作符之前，例如： </p>
            <p class="article"> op operator //后缀记号</p>
            <p class="article"> 所有的双元操作符使用中缀记号，即操作符出现在两个运算对象的中间： </p>
            <p class="article"> op1 operator op2 //中缀记号</p>
            <p class="article"> 三元操作符也是使用中缀记号，例如： </p>
            <p class="article"> op1 ? op2 : op3 //中缀记号</p>
            <p class="article">操作除了执行一个操作，还返回一个数值。返回数值和它的类型依靠于操作符号和运算对象的类型。比如，算术操作符它完成基本的算术操作（加、减）并且返回数值作为算术操作的结果。由算术操作符返回的数据类型依靠于它的运算对象的类型：如果你对两个整型数相加，你就会得到一个整型数。</p>
            <p class="article"> 我们可以将操作符分成以下几类： </p>
            <p class="article"><span class="coffee">算术运算符</span></p>
            <p class="article"><span class="coffee">关系和条件运算符</span></p>
            <p class="article"><span class="coffee">移位和逻辑运算符</span></p>
            <p class="article"><span class="coffee">赋值运算符</span></p>
            <p class="article"><span class="coffee">其它的运算符</span></p>
