Java获取系统参数 博客分类： java javajdksun

最近由于要通过Java获取系统参数，苦于资料不全，就自己写了个方法来获取系统参数，代码如下：

import java.util.Enumeration;
import java.util.Properties;
/**

 */

public class SystemProperties {
	public static void main(String[] args) {
		Properties pros=System.getProperties();
		Enumeration<?> keys=pros.keys();
		while(keys.hasMoreElements()){
			String prokey=(String) keys.nextElement();
			String provalue=System.getProperty(prokey);
			System.out.printf("%-35s%-20s\n", prokey,provalue);
		}
	}
}

 执行结果如下：
