Difference Between these?

String s1= new String("java") ;
String s2="java" ;

and also

what for 2 different classes are there in garbage collection?

System.gc and runtime.gc ( both are doing the same job)
what is their individual role?

please anyone explain me....

execJAVA currently am using this exe converter from jar file.

but its trial version only.

you can download this from www.JavaAPIs.com

anyway you have to convert your application in to jar format.

vinod_javas 65 Practically a Posting Shark

If you want to create Exe means you have to go for third party tool.

vinod_javas 65 Practically a Posting Shark

you can create jar for your project

you have to make manifest file

Manifest-Version: 1.0
Specification-Title: Java Utility Classes
Created-By: 1.5.0 (Sun Microsystems Inc.)
Main-Class: maninclassname

save it as manifest.mf keep this file in current project folder.

and go to project location then type in command prompt:

jar cmf manifest.mf anyname.jar *.*

press enter then you will get your jar file created.

if you have better way more than this means please show your solutions also. it will be really useful

(for adding zero)


class doubconv
{
public static void main(String args[])
{
String code="00000000001";
int leng=code.length();
int cnt=0;
for(int j=0;j<leng;j++)
{
char c=code.charAt(j);
if(c=='0')
{
cnt++;

}
else
{
break;
}
System.out.println(cnt);
}
String si="";
for (int k=0;k<cnt ;k++ )
{
si=si+"0";
}
double dbl=Double.parseDouble(code);
double dbl1=dbl+1;

String result=si+dbl1+"";

System.out.println(result);


}
}

java.sun.com will provide you good tutorials.

so just go through that tutorials

All the very best.

vinod_javas 65 Practically a Posting Shark

Have this as example.......

class doubconv
{
public static void main(String args[])
{
String code="00000000001";
double dbl=Double.parseDouble(code);
double dbl1=dbl+1;
String result=dbl1+"";

System.out.println(result);


}
}

vinod_javas 65 Practically a Posting Shark

first better way... is try to run programs in command prompt thats is the best way to start a learning step for java

install jdk 1.5 or latest 1.6

then set your class path

compile it

javac programname.java


and run

java programname

you will get the output in the command prompt console itself

vinod_javas 65 Practically a Posting Shark

I dont think you can use hyperlink in windows application

its only for web application

vinod_javas 65 Practically a Posting Shark

Just download J2ME wireless toolkit 2.5 for developing mobile application.... it is very nice IDE provided by Sun.

you will be having demo projects inside the toolkit.. just go through all those surely you will be getting a good idea about developing new Mobile application.

All the Very Best...

and simply if you type java -help means you will get list of items for help

in that itself it contains the java -version

from that you can get to know about the version that you are using.

Farmer John was taking his cow and its new born calf to sell in the auction.
On the way farmer John got robbed by thieves, who beat him up, stripped him of his clothes and tied him to a tree.
Then taking the mother cow and John's clothes, the thieves escaped.
They however left the new born calf behind.

Poor farmer John suffered as for two days, he stood tied to a tree, stark naked and hungry.
Fortunately, on the third day, some neighbors happened to pass by.
They recognized John and untied him.

When they did, farmer John picked up a huge stick and started bashing the calf with it.
"Why are you thrashing the poor calf? His neighbors asked?
To which farmer John replied…


"I have been telling this beast for the past two days repeatedly - I am not your mother! I am not your mother...I'm not your mother...!"

for that you have to get the rowcount value for that particular table and then keep that value in that place of int row_to_display =

i dont know the exact method for getting row count value..

just search in google for getting Rowcount value... i think it may be getRowCount()

vinod_javas 65 Practically a Posting Shark

hi sunitha its no need to make new thread like this you could have added this code in your previous thread itself.... so you can get continuity for your problem solving.

vinod_javas 65 Practically a Posting Shark

int row_to_display = 200 ;
FPSProdMap[] oProdMap= dbFpsProdMap.getProdMap(sLang,1,200);


change that value 200 to your number of records like if it is 1000 means change it in to 1000

vinod_javas 65 Practically a Posting Shark

you have to convert your application in to executable jar file..

for that you have to follow some procedure

you have to create manifest file

in that manifest file you have to mention your main class name like below.

Manifest-Version: 1.0
Specification-Title: Java Utility Classes
Created-By: 1.5.0 (Sun Microsystems Inc.)
Main-Class: mainclassname

and save it as manifest.mf and keep this file in project location.

and then you have to run the following command in DOS prompt

(go to projetlocation via command prompt)
jar cmf manifest.mf filename.jar *.*

then you will get your executable jar file

yea thanks i will try that first..

vinod_javas 65 Practically a Posting Shark

Go back to reply number 1.

i dont have any idea about server socket thats why looking for alternate solution....

vinod_javas 65 Practically a Posting Shark

here is my code...

try {
        // Get a file channel for the file
        File file = new File("filename");
        FileChannel channel = new RandomAccessFile(file, "rw").getChannel();
    
        // Use the file channel to create a lock on the file.
        // This method blocks until it can retrieve the lock.
        FileLock lock = channel.lock();
    
        // Try acquiring the lock without blocking. This method returns
        // null or throws an exception if the file is already locked.
        try {
            lock = channel.tryLock();
        } catch (OverlappingFileLockException e) {
            // File is already locked in this thread or virtual machine
        }
    
        // Release the lock
        lock.release();
    
        // Close the file
        channel.close();
    } catch (Exception e) {
    }
vinod_javas 65 Practically a Posting Shark

Glad it works for you. Keep in mind the points jwenting mentioned though. I don't think you will have those issues with the code I pasted, but testing is your best friend.

Be sure you release the lock and close the channel when you no longer need them:

lock.release();
lockChannel.close();
lockFile.delete();

yea i have used all these... but if i rename the jar file means its worthless... its again opening multiple instances
