In this tutorial how to\u00a0 create a program to check a number is Armstrong number or not in Core Java\u00a0 is shown.<\/p>\n
Code:<\/p>\n
Armstrong.java<\/p>\n
class CheckArmstrong
\n{
\npublic static void main(String args[])
\n{
\nint number=Integer.parseInt(args[0]),sum=0,r,copyn;
\ncopyn=number;
\nwhile(copyn>0)
\n{
\nr=copyn%10;
\nsum+=(r*r*r);
\ncopyn\/=10;
\n}
\nif(sum==number)
\nSystem.out.println(number+” is Armstrong number”);
\nelse
\nSystem.out.println(number+” is not Armstrong number”);
\n}
\n}<\/p>\n
