Java中获取系统属性
在使用Java进行开发的时候,常常需要用到系统的一些属性,可以通过调用java.lang.system类中的getProperties()方法或getProperty(String key)方法来获取当前系统的属性。
1java.util.Properties currentProperties = System.getProperties();//获取当前系统所有的属性
2currentProperties.list(System.out);//在屏幕上输出
2currentProperties.list(System.out);//在屏幕上输出
// 通过指定属性名,获取相应的系统属性
1String osName = System.getProperty("os.name");
2String osVersion = System.getProperty("os.version");
3String osArch = System.getProperty("os.arch");
4String userName = System.getProperty("user.name");
5String userHome = System.getProperty("user.home");
6String userDir = System.getProperty("user.dir");
7String userTimezone = System.getProperty("user.timezone");
8String javaHome = System.getProperty("java.home");
9String javaVersion = System.getProperty("java.version");
10String javaClassPath = System.getProperty("java.class.path");
11String javaClassVersion = System.getProperty("java.class.version");
12String javaVendor = System.getProperty("java.vendor");
13String javaVendorURL = System.getProperty("java.vendor.url");
14String pathSeparator = System.getProperty("path.separator");
15String lineSeparator = System.getProperty("line.separator");
16String fileSeparator = System.getProperty("file.separator");
17String fileEncoding = System.getProperty("file.encoding");
1String osName = System.getProperty("os.name");
2String osVersion = System.getProperty("os.version");
3String osArch = System.getProperty("os.arch");
4String userName = System.getProperty("user.name");
5String userHome = System.getProperty("user.home");
6String userDir = System.getProperty("user.dir");
7String userTimezone = System.getProperty("user.timezone");
8String javaHome = System.getProperty("java.home");
9String javaVersion = System.getProperty("java.version");
10String javaClassPath = System.getProperty("java.class.path");
11String javaClassVersion = System.getProperty("java.class.version");
12String javaVendor = System.getProperty("java.vendor");
13String javaVendorURL = System.getProperty("java.vendor.url");
14String pathSeparator = System.getProperty("path.separator");
15String lineSeparator = System.getProperty("line.separator");
16String fileSeparator = System.getProperty("file.separator");
17String fileEncoding = System.getProperty("file.encoding");
