hi
i have wrote this progaram in java.
it finf the palidrome numbers and print it.
its by threads

it has some errors and i can t run it.
please help me.

package palindromen;
import java.lang.Integer;
import java.lang.String;

public class Main {

public Main() {
}

public static void main(String[] args)
{int nop,anyt;
Keyboard key=new Keyboard();
System.out.println("Enter number of processors : ");

nop=key.readInt();
anyt=20000/nop;

T Threads[]=new T[nop];
Palindromeset p=new Palindromeset();
for(int i=1;i<=nop;i++) {
Threads=new T("Threads"+Integer.toString(i));
Threads.setr((i*anyt),anyt*(i+1),p);

}

for(int i=1;i<=nop;i++)
Threads.start();

for(int i=1;i<=nop;i++)
try{
Threads.join();
}
catch(Exception e)
{ }

p.print();

}

}

-------------------------------------

package palindromen;


public class Palindromeset extends Thread{
private int buffer[];
private int count;

/** Creates a new instance of Palindromeset */
public Palindromeset() {
count=0;
buffer=new int[20000];
}


public synchronized void addNum(int x)
{buffer[count]=x;
count++;
}

public void print(){
for(int i=0;i<count;i++)
{ System.out.println(buffer);
System.out.println(" ");
}
System.out.println();
System.out.println(count);

}

}
-------------------------------------------------

package palindromen;


public class T extends Thread{


public int lowr,highr,n;

volatile Palindromeset c;


public void setr(int lr,int hr,Palindromeset pt)
{
lowr=lr;
highr=hr;
c=pt;}


public T(String s) {

this.setName(s);
}

public void run()

{for(int i=lowr;i<highr;i++){


n = i; //used at last time check

int reverse=0,remainder;

while(i > 0){

remainder = i % 10;

reverse = reverse * 10 + remainder;

i = i / 10; }

if(reverse == n)
c.addNum(i);
}
}
}

1) use code tags
2) tell us what those errors are, we're not going to guess
3) most errors are pretty self explanatory, try figuring out what they mean by yourself. It's a vital skill to develop.
