JDK 2 1.3

[Benjamin]

I have no clue what I am doing...
I just downloaded JDK 2 1.3

and I tried writing a java program

main()
{
print "hello";
return 0;
}

I named it with a java extension.
then I did this in an MS DOS console

C:\WINDOWS>cd ..
C:\>cd jdk1.3
C:\JDK1.3>java c:\java\test.java

c:\java\test.java is the full path to my java file...

it gives me an error, I can post the error if you want...


Thanks

This will print out Hello World! ten times on the screen.
If you compile your program you will get erors.
To compile type in cd C:\jdk1.3\bin this will get you to
where the compiler and interpeter is located
then javac C:\java\test.java.
To run your program java -classpath C:\java; test




/***
* The HelloWorld class implements an application that
* simply displays "Hello World!" to the standard output.
*/
class HelloWorld {
public static void main(String[] args) {
for (int i = 0; i <= 10; i++){
System.out.println("Hello World!"); //Display the string.
}
}
}

the code you gave me "compiled" fine, but it doesn't work when I try to execute it..

I type

c:\jdk1.3\bin>java c:\java\helloworld.class

Try Dilenger4's instructions. An executable class must take most of that format.

public class WatchMyCamelCase{
public static void main(String[] args){

Required signature--only variants are VarName and location of brackets (String anyName[])

main does not return anything, hence "void".

Drop the .class
Try
c:\jdk1.3\bin>java c:\java\helloworld
or more likely
c:\jdk1.3\bin>java c:\java\HelloWorld

All
Watch the CamelCase for HelloWorld!

I removed the return,
and I tried what you said

c:\jdk1.3\bin>java c:\java\HelloWorld


and it said:

Exception in thread "main" java.lang.NoClassDefFoundError: c:\java\HelloWorld



and this is my exact code

class helloworld{
public static void main(String[] args)
{
System.out.println("hello");
}
}

If the name of your class is HelloWorld then to
compile it should be
c:\jdk1.3\bin>java -classpath c:\java; HelloWorld

thanks a lot! it works

The easiest way to run Class files is to add "C:\SDK1.3\bin" or wherever you installed it to the path variable in autoexec.bat, andthen you can run a class file located in (for example) "C:\Java\Class" this way:

C:\>cd C:\Java\Class
C:\Java\Class>java HelloWorld.class

and hey preto, it works!

This way, you can also compile files a lot easier, ie

C:\Java>javac HelloWorld.java

java (meaning java.exe) doesn't like to see .class
javac (meaning javac.exe) likes to see .java
