Solution:

To bring up System Properties:

1.       Click Start and then Control Panel. From the Control Panel, double click System.

2.        Another way to bring up this box is to right click the My Computer on your desktop. From the menu, select Properties.

Solution:

1.       参考http://www.passcape.com/windows_run_commands

除了这两种方式外，还有一种直接运行system32下面的命令文件方式

运行C:"WINDOWS"system32 下面的sysdm.cpl。

11//如果如下定义，就会在编译时出现一个错误，因为不是覆盖父类的方法
12@Override
13 public void method(int i, String p_Str) {

JDK1.6正常，支持对接口的实现的@Override

 1public interface iA {
 2
 3 public void method(int i) {
 4
 5 }
 6
 7}
 8
 9public class B implements iA {

11 //JDK1.5下会报错，JDK1.6下可以
12
13 @Override
14
15 public void method(int i, int j) {
16
17 }

Analisys:

安装Oracle Client 9/10后, Path 被设置为Oracle自带的JDK 1.4, 启动高版本Eclipse(eclipse-jee-helios-SR1-win32.exe)时,　就默认用Oracle自带的JDK 1.4，这样就会有问题。

Solution:

多种解决方案

1.       修改环境变量：　Path = %JAVA_HOME%"bin;%PATH% 
权限的问题，我没有选择这个解决方案。

2.       修改Eclipse启动项：修改Eclipse快捷方式的属性里面的目标：　
D:"tool"eclipse-jee-helios-SR1-win32"eclipse"eclipse.exe　-vm "C:"Program Files"Java"jdk1.5.0_05"bin"javaw.exe"

Eclipse报错:   must override a superclass implements

Analisys:
1. @override 可以针对 Interface; 不过最好用另外一个annotation: @implement
2. java5 java6 支持泛型
3. eclipse 里面的compile版本是JDK 5

Solution:
eclipse 里面的compile版本是JDK 5 -> 改成 JDK6
