如何将 Java的环境变量列入Windows(类别)?
Java SE Development Kit 8u112 on a 64-bit Windows 7 or Windows 8
设定以下
JAVA_HOME :
C:Program FilesJavajdk1.8.0_112
JDK_HOME :
%JAVA_HOME%
JRE_HOME :
%JAVA_HOME%jre
CLASSPATH :
.;%JAVA_HOME%lib;%JAVA_HOME%jrelib
PATH :
your-unique-entries;%JAVA_HOME%in
(make sure that the longishyour-unique-entries
does not contain any other references to another Java installation folder.
视窗用户在64轨道系统中的说明:
Progra~1 = Program Files
Progra~2 = Program Files(x86)
这些环境变量来自“root”环境变量JAVA_HOME
。 这使得在更新联合数据系统时很容易更新你的环境变量。 Just point JAVA_HOME
to the new facilities.
Optional recommendations
- Add a user environment variable
JAVA_TOOL_OPTIONS
with value-Dfile.encoding="UTF-8"
. This ensures that Java (and tools such as Maven) will run with aCharset.defaultCharset()
ofUTF-8
(instead of the defaultWindows-1252
). This has saved a lot of headaches when wirking with my own code and that of others, which unfortunately often assume the (sane) default encoding UTF-8. - When JDK is installed, it adds to the system environment variable
Path
an entryC:ProgramDataOracleJavajavapath;
. I anecdotally noticed that the links in that directory didn t get updated during an JDK installation update. So it s best to removeC:ProgramDataOracleJavajavapath;
from thePath
system environment variable in order to have a consistent environment.

<>Step 4: 为JAVA-HOME创建新的班级道路
<>Step 5: 进入Variable name as JAVA_HOME and the Value to You jdk bin path ie c:ProgramfilesJavajdk-1.6in and

in the Value so that it don t corruption the other environment factors which is established.
<>Step 6: 跟踪系统可变物质的“路径”和代号,在价值栏中添加以下内容:
Step 7:Your is made up the environment factors for You Java , 为了测试,它必须迅速指挥。

有两种办法可以确定 j路。
www.un.org/Depts/DGACM/index_french.htm
- Open cmd
- Write in cmd :
javac
如果不安装java,你就会看到以下信息:
javac未被承认为内部和外部指挥、可操作的方案或批量文件。
- Write in cmd :
set path=C:Program FilesJavajdk1.8.0_121in
- Write in cmd :
javac
如果未发现错误,你可以检查这条道路。
必须指出,这些变化只是从这一厘米点启动的方案的临时变化。
<>m>NOTE:你可能不得不将指挥线作为admin。
<>B. 永久
- Righ-click on "My computer" and click on properties
- Click on "Advanced system settings"
- Click on "Environment variables"
- Click on new tab of user variable
- Write
path
invariable name
- Copy the path of bin folder
- Paste the path of the bin folder in the
variable value
- Click OK
这条道路现已永久开通。
www.un.org/Depts/DGACM/index_spanish.htm TIP: The tool “Rapid Environment Editor” (freeware) is grand for changinging the environment factors and help in that case
%windir%System32 undll32.exe sysdm.cpl, EditEnvironmentVariables
and press ENTER
Windows 7,right-click on Computer ->Properties ->先进系统环境;然后在Advancedtab,点击Environment Variables... ->系统变量 ->New...。
新的系统可变以下名称:JAVA_HOME
和价值C:Program filesJavajdk1.7.0_79
(取决于您的JDK安装方式)。
然后选择<代码>Path系统变量,并点击Edit......。 保留<代码>Path和附录C:Program filesJavajdk1.7.0_79in;
或%JAVA_HOME%in;
(两者均指)变值。
一旦做了上述改动,就会尝试以下步骤。 如果你看不到类似结果,就重新启用计算机并再次尝试。 如果仍然不工作,你可能需要重新加入科索沃独立党。
开放窗口指挥台(Windows Key + R-> 进入cm
->OK,并检查:
java -version
你们会看到这样的情况:
java version "1.7.0_79"
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)
然后检查:
javac -version
你们会看到这样的情况:
javac 1.7.0_79
JDK 安装指示准确解释如何为不同版本的Windows设定PATH
。
通常,你不应制定<代码>。 CLASSPATH 环境变量。 如果你离开, Java将看目前的名录,寻找班级。 页: 1 指挥线改为<代码>java或javac
。
我将在这里通过视窗7的图片作解释。
请采取以下步骤:
Step 1: Go to "Start" and get into the "My Computer" properties
Step2:Go to “Advance System Setting” and Point on it.
Step 3: Go to “Start” and go into the “My Computer” nature
<>Step 4:环境变量的方言将照此开放:

Step 6:Put the path of You JDK where it Residents up to bin Suchs. 此外,在平台工具上添加从您的安康到的道路。
在方案拟定方面,你可以执行SET指挥系统(SET等级=c:java)或右边点击你的计算机和镜头;财产“超高”;环境变量。
在批量档案中,可使用
SET classpath=c:java
java c:myapplication.class
视窗7用户:
Right-click on My Computer, selected Property; Superior; System Settings; Superior; Environment Variables. 然后在第二个盒子中找到PATH,并像下文中那样确定变量。
当然,你可以利用:
String variable = System.getProperty("mykey");
www.un.org/Depts/DGACM/index_spanish.htm Set java Environment changing in Centos /-030
/home/ vi.bashrc
出口 JAVA_HOME=/opt/oracle/product/java/jdk1.8.0_45
PATH=$JAVA_HOME/bin:$PATH
java - 转化
铭记%CLASSPATH%
environment/2007/5> 当你使用java/javac与-cp
、-classpath
或-jar<>/code>。 它还在Netbeans/Eclipse/IntelliJ/etc等电离层电离层中ignored。 当你使用java/javac时,就使用了
如果是联合调查组的档案,则该类别将界定为“标识”条目。 mf 档案。 它可以被定义为分立的半殖民地,而与JAR的档案相对而言是根本的。
如果是民主选举学会,你就拥有所谓的建筑道路,这基本上是在汇编时间和操作时间使用的班次。 为增加外部图书馆,您通常将JAR的档案放入(由民主选举学会或定制的)lib
,该项目的复印件添加到项目修建的道路上。
For deployment better to set up classpath exactly and keep environment clear. Or at *.bat (the same for linux, but with correct variables symbols):
CLASSPATH="c:lib;d: emp est.jar;<long classpath>"
CLASSPATH=%CLASSPATH%;"<another_logical_droup_of_classpath"
java -cp %CLASSPATH% com.test.MainCLass
或者在指挥线或 *.bat(就*.sh而言)上,如果班时间不够长:
java -cp "c:lib;d: emp est.jar;<short classpath>"
视窗:
- Right click on My Computers and open Properties .
- In Windows Vista or Windows 7, go to "Advanced System Settings". Else go to next step.
- Go to Advanced Tab and click on Environment Variables button.
- Select Path under the list of System Variables , and press Edit and add
C:Program Filesjavajdkin
after a semicolon. - Now click on new button under system variables and enter JAVA_HOME as variable name and path to jdk home directory (ex. C:Program FilesJavajdk1.6.0_24 if you are installing java version 6. Directory name may change with diff. java versions) as variable_value.
您的钥匙tools档案存放在“Java/bin”的夹子下,因此,你需要确定环境变数,或去“Java/bin”的夹子,管理指挥。
可在系统环境中添加JAVA_HOME,从我的计算机和软件中可变;>advance tab>add the new path as amended rel=“nofollow noretinger”>here。
