System.getProperty()获取系统的相关属性

我们在编程的过程中有时候需要获取系统的相关属性，今天就让我们一起来学习学习如何获取系统的相关属性

至于System.getProperty(param)中的各个参数的概念请看下表。

具体的代码示例如下:

   package com.yonyou.test;

/**
 * 测试类
 * @author 小浩
 * @创建日期 2015-4-18
 */
public class Test{
	public static void main(String[] args){
		new Test().test();
}

public void test(){
    System.out.println("java_vendor:" + System.getProperty("java.vendor"));
    System.out.println("java_vendor_url:"
             + System.getProperty("java.vendor.url"));
    System.out.println("java_home:" + System.getProperty("java.home"));
    System.out.println("java_class_version:"
             + System.getProperty("java.class.version"));
    System.out.println("java_class_path:"
            + System.getProperty("java.class.path"));
    System.out.println("os_name:" + System.getProperty("os.name"));
    System.out.println("os_arch:" + System.getProperty("os.arch"));
    System.out.println("os_version:" + System.getProperty("os.version"));
    System.out.println("user_name:" + System.getProperty("user.name"));
    System.out.println("user_home:" + System.getProperty("user.home"));
    System.out.println("user_dir:" + System.getProperty("user.dir"));
    System.out.println("java_vm_specification_version:"
            + System.getProperty("java.vm.specification.version"));
    System.out.println("java_vm_specification_vendor:"
            + System.getProperty("java.vm.specification.vendor"));
    System.out.println("java_vm_specification_name:"
            + System.getProperty("java.vm.specification.name"));
    System.out.println("java_vm_version:"
            + System.getProperty("java.vm.version"));
    System.out.println("java_vm_vendor:"
            + System.getProperty("java.vm.vendor"));
    System.out
            .println("java_vm_name:" + System.getProperty("java.vm.name"));
    System.out.println("java_ext_dirs:"
            + System.getProperty("java.ext.dirs"));
    System.out.println("file_separator:"
            + System.getProperty("file.separator"));
    System.out.println("path_separator:"
            + System.getProperty("path.separator"));
    System.out.println("line_separator:"
            + System.getProperty("line.separator"));
}
}
