使用Java查询当前操作系统的位数以及电脑的硬件信息，可显示操作系统 是32位还是64为系统。
使用Java查询当前操作系统的位数以及电脑的硬件信息
• 阅读 (3445) | 收藏 (0) | 点赞 (0)如果想了解如何使用JavaScript来查询和获取当前操作系统的位数，请查看我的上一篇文章：javascript 获取操作系统是否是32位还是64位系统。
直接上代码：
package com.blog.test;
import java.util.Iterator;
import java.util.Map.Entry;
import java.util.Properties;
/**
* Java 获取操作系统的信息，包含系统的是否是32位或者64位

*/
public class TestSystemByte {
public static void main(String args[]) {
System.out.println( System.getProperty("os.name") ); //操作系统名称
System.out.println( System.getProperty("os.version") ); //操作系统版本
System.out.println( System.getProperty("os.arch") );//操作系统构架
System.out.println("------------------------------------------------------------");
//还可以获取到当前操作系统的所有的参数，并遍历打印参数
Properties props = System.getProperties(); // 获得系统属性集
showKeysAndValues(props);
}
/**
* @param properties
*/
private static void showKeysAndValues(Properties properties) {
Iterator<Entry<Object, Object>> it = properties.entrySet().iterator();
while (it.hasNext()) {
Entry<Object, Object> entry = it.next();
Object key = entry.getKey();
Object value = entry.getValue();
System.out.println("key :" + key);
System.out.println("value :" + value);
System.out.println("---------------");
}
}
}打印的结果如下：

上述代码即可获取操作系统的位数，同时可以获取当前操作系统的其他信息，包含JDK版本等等。
