Write a JAVA program which will generate following threads I. To display 10 terms of Fibonacci series. II. To display 1 to 20 in reverse order

import java.io.*;
class fib extends Thread

{
 public void run()
 {
   try

{

int a=0,b=1,c=0;
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter the Limit");
int n=Integer.parseInt(br.readLine());
System.out.println("Fibonacci series:");
while(n>0)
{
  System.out.println(c);
a=b;
b=c;
c=a+b;
n=n-1;
}
}
catch(Exception e)
{
}
}
}
class rev extends Thread
{
 public void run()
{
try
{
System.out.println("Reverse is");
for(int i=20;i>=1;i--)
System.out.println(i);
}

catch(Exception e)
{
 }
}
}
class s16
{
public static void main(String args[])
{
 try
{
  fib t1=new fib();
t1.start();
t1.sleep(5000);
rev t2=new rev();
t2.start();
}
catch(Exception e)
{
}
}
}


output:-
