# CPU核数

获取可用处理器数目的Java代码示例：

```
public class SystemProperty {
public static void main(String args[]) {
int availProcessors = Runtime.getRuntime().availableProcessors();
System.out.println("avail processors count: " + availProcessors);
}
}
```

鲲鹏上执行结果：

```
[root@centos7 test]# java SystemProperty
avail processors count: 16
```
