Programming that Prints out Tribonacci Number below 1600

import java.math.BigInteger;
public class Tnumber{
public static void main (String []args){
BigInteger first=BigInteger.valueOf(0),second=BigInteger.valueOf(1), third=BigInteger.valueOf(1),sum=BigInteger.valueOf(0);
int c=0;
System.out.println("First 1600 Tribonacci Number is =\n" + first);
System.out.println(second);
System.out.println(third);
while(c<1600){
sum=first.add(second).add(third);
System.out.println(sum);
first=second;
second=third;
third=sum;
c++;
}
}
}
Like this programme you can also create the programme of Tetranacci Number, Pentanacci Number, Hexanacci Number, Heptanacci Number etc.
