Setting a path in java



i know that i should use this to compile all the java classes . i used these and its working great. but i dont understand all of this . i did some readings and i understand now that when i use "set" , it sets the varibale name to the string after the equal sign. i know what lines 1 and 2 mean. but what about line 3, 4 and 5 !?:-/ can you please help explaning them to me ! thank you:)



  

1. set AGLET\_HOME=C:\Users\MARIA\Desktop\aglets



2. set JDK\_HOME=C:\Users\MARIA\Java\jdk1.6.0\_18



3. set CLASSPATH=.



4. set CLASSPATH=%CLASSPATH%;%AGLET\_HOME%\lib\myJarFile.jar



5. %JDK\_HOME%\bin\javac -d %AGLET\_HOME%\public -classpath %CLASSPATH% *.java
When Java needs to load a class it gets the variable "CLASSPATH", which should contain a list of directories and/or jar files, and searches all those locations to find the .class file(s).  

Line 4 appends %AGLET\_HOME%\lib\myJarFile.jar to the CLASSPATH variable.  

AGLET\_HOME was set to C:\Users\MARIA\Desktop\aglets, so line 4 appends the jar file  

C:\Users\MARIA\Desktop\aglets\lib\myJarFile.jar  

to the CLASSPATH, so java will be able to find whatever classes are stored in that jar.
hi there! a member variable (or field) is simply a variable that belongs to that class. you create it just like you would any other. in this case, it wants a public string.
```java
public string title;
```
this creates a field/member variable that belongs to this class. it is public, of type string and has the name title. 
hope this helps! :sparkles: hi [@gus\_fring](/u/gus_fring)

welcome to community :slight\_smile:

you have to set the path with the file name. not only the path of folder.

for example you have the folder temp in c and the file name is inputdata.xlsx

your path should be then: c:\temp\inputdata.xlsx

best regards

mahmoud i've been meaning to write a blog post on this for a while, but haven't got round to it yet, so i'll give the condensed version here :slight\_smile:

to understand why the if let syntax is the way it is, we should first look at the let syntax. in most cases, you'll see it used for simple variable dec… so if you want to be able to run them as separate runs, you’ll still need some way of communicating between them. one mechanism we provide for that is by serializing daml values as json through the --input-file and --output-file options to daml script. so in your case, you should make sure that the … hi

we can do that by defining a string variable in the very beginning of the process with assign activity or by defining that in variable panel in the studio at the bottom the window

but make sure that we are not assigning any value to that variable later across the workflow

if we assign later th… looking around i think i found the answer myself.

there is are batch and script files in jabref/runtime/bin.

from those, the needed command line call can be derived. using the shipped jvm from inside the mentioned folder the call i looked for would be:

java --add-opens=javafx.controls/javafx.scen… Try it like this:



```
pathDiagram(
              model=ete.sem
            , file="PathDiagram"
            , max.rank=paste("item", 1:17, sep="")
            , ignore.double=FALSE
            , edge.labels="values"
            , size=c(8, 8)
            , node.font=c("Helvetica", 10)
            , edge.font=c("Helvetica", 10)
            , rank.direction="LR"
            , digits=3
            , standardize=TRUE
            , graphics.fmt="pdf"
            )

        

        
        
        
 (adsbygoogle = window.adsbygoogle || []).push({});
 
        

    
```


  




 (adsbygoogle = window.adsbygoogle || []).push({});
 
  

This will create it `PathDiagram.pdf`
  




 (adsbygoogle = window.adsbygoogle || []).push({});
 
  

in your working directory. I don't know anyway to display the graph in R.


 ![enter image description here](https://fooobar.com//img/766a7d8d75d3c8dae69e8be5738bed8a.png) How you do this will depend on a number of factors: since you haven't tried to explain in any detail, I'll assume you know nothing, and just give you the basics.  

  

The easiest way to do this is to read the text file into a single string, and then use the .NET framework to find the match:  


```
Dim text As String = File.ReadAllText("D:\Temp\MyFile.txt")
Dim index As Integer = text.IndexOf("hello")
If index >= 0 Then
   ' String is in file, starting at character "index"
End If
```
  

There are other ways, but that is pretty much the simplest. method a.increment() overlaps in class b.   
 therefore, regardless of the type of the variable obj, will be called the method corresponding to the actual type of the object - that is, b.increment().  
 
this method will use the variable i, declared in the same class b and having an initial value of 10.  
 
the resulting value - 11. thanks for your comment!

i definitely should’ve used mkshell, not sure why i wasn’t. it does seem to produce a different error:
