java

[himtuna]

I have installed
J2SE runtime Environment 5.0 udate 4 from August Autopachter.
I don't know anything of Java but I checked October's EFY it had a calender.
I want to know if I need to install J2SE(TM) Development Kit 5.0 Update 5
or above installed component is same.
EFY instructs to install Bluej 2.0.1 also that I have downloaded but JDK is about 60 MB.
I just want to try out java.

Nobody answered
but i got the answer after searching the java site carefully.
JDK 5.0 or J2SE is a part of J2SE(TM) Development Kit 5.0 Update 5. It a superset of J2SE runtime Environment 5.0 udate 4 as it contains debugging, compiling & editing the java prog.

I have installed j2se update 5.0 with netbeans 4.1

By defualt the path execution path for python was there.
so I created a new exe. path for java
And typed variable name as PATH
and variable value as c:\jdk\bin; "but forgot to type the other windows stuff"
exe. path for python is ovewritten and new path value "c:\jdk\bin;"was there
In dos prompt I typed "java -version" to check the path
It gave me java: commond not found Bad command or file name.....

Please give me the that other stuff that I must write to setup the exe. path
or restoring the computer will solve the problem

did you create the environment variable for java? specify the path in the au*.bat file. path=%path%;new path. do you able to execute the command in c:\jdk\bin?

This info is too technical for me to understand.
what is "au*.bat file" ?

I have restored the computer and solved the problem but
what about python????
and one more problem
can't install library sources
In shell command I created src (dir) in jdk 5.0(dir) and executed the following jar xvf ..\src.zip and even tried jar xvf jdk 5.0\src.zip
and got the message 'jar' is not blaa blaa blaa .
How to install the library?
I am new to java and refering to core java2 (7th-edition) to learn it. ofcourse it is a difficult language to learn on your own but still I'll prefer to built some basic concepts of java by own, book and online resources.
I will do a course to learn java when I have time (probably during summer holidays.)May I know how you learned java and Hoe must I procede to master it ?
Is c# a better option?

what he mentioned is the autoexec.bat file on your root drive. (probably C:\ drive)

Well i wonder what are you trying to do with a zip file ? The jar comand is meant for compressing/extracting java jar archives. not zip files.(correct me if i'm wrong).

1/ au*.bat= AUTOEXEC.BAT ---- if you are using win98.... youshould provide the path for java. you have to create the environment variable in 2000 for path -- in simple words. i guess that yo are aware from variables.

2/ --- i know that python is belongs to snake family --- sorry just kidding ... no idea as im newbie for pearl/python.

3/ C >> C++ >> JAVA >> C# ===== this the family chain as i think .. [C++ reqs C knowldge; Java req C++ kn'de; C# req Java knl'ge]

4/ i have learned java by myself -- actually we have the java in our prosp in BSc. it was introduction to java upto Applet. i have learned abit more when i joined GNIIT only for Java [adv java] and .NET with SQL 2000. after that i bought a book WEBER using JAVA 2 platform and have some practice. this is a very nice book for introducers. the most inter'ting parts in java [and i liked most] is Threading and Socket Programing.... i have created one simple chatting program for a single Network. i don't like RMI stuffs.

5. be a master of JAVA, you have to start from Core. you should have a know'ge of C.
