<p align="JUSTIFY">关系运算符的结果是步尔值，也就是只有“真”和假两种答案，例如：<br>
int x=5,y=7;<br>
boolean b=(x==y);</p>
<p align="JUSTIFY">则b的值是false。也就是0，计算机中用0可以代表false。</p>
<p align="JUSTIFY">4)其他运算符<br>
1.三目运算符<br>
Java中的三墓运算符与C语言中的完全相同，使用形式为：<br>
x?y:z;<br>
这就是说，先计算x的值，若x为真，怎整个表达式的结果为y的值，若x为假，则整个表达式的值为表达式z的值。<br>
例如：<br>
int x=5,y=8,z=2;<br>
int k=x<3?y:z; //因为x<3，所以k=2；<br>
int j=x>0?x:-x //y的值始终为x的绝对值。</p>
<p align="JUSTIFY">2.逻辑运算<br>
逻辑运算是针对布尔型数据进行的云酸，运算的结果仍然是布尔型量。常用的运算符如下：</p>
<table width="570" border="1" bordercolor="#FF9999">
<tr bordercolor="#FF9999">
<td width="143">
<div align="center">运算符</div>

</td>

<tr>
<td>&</td>
<td>非简洁与</td>
<td>x&y</td>
<td>x,y都真时结果才为真</td>
</tr>
<tr>
<td>|</td>
<td>非简洁或</td>
<td>x|y</td>
<td>x,y都假时结果才为假</td>
</tr>
<tr>
<td>!</td>
<td>取反</td>
<td>!=x</td>
<td>x真时为假，x假时为真</td>
</tr>
<tr>
<td>^</td>
<td>取或</td>
<td>x^y</td>
<td>x,y同真假时结果为假</td>
</tr>
<tr>
<td>&&</td>
<td>简洁与</td>
<td>x&&y</td>
<td>x,y都真时结果才为真</td>
</tr>
<tr>
<td>||</td>
<td>简洁或</td>
<td>x||y</td>
<td>x,y都假时结果才为假</td>
</tr>

<p align="JUSTIFY">3.位运算<br>
位运算是对操作数以二进制为单位进行的操作和运算，位运算的操作数和结果都是整形变量。常用的规则列表如下：</p>
<table width="570" border="1" bordercolor="#FF9999">
<tr>
<td width="77">
<div align="center">运算符</div>
</td>
<td width="127">

<p align="JUSTIFY">2.复杂运算符<br>
复杂运算符是在先进行某种云酸后，再把运算结果赋给变量。举例如下：<br>
