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
