*Armstrong Number= { int num=370,number,temp,total=0; number=num; while(number!=0) { temp=number%10; total=total+temp*temp*temp; number/=10; } if(tota==num) System.out.println(num+"is an Armstrong Number"); else System.out.println(num+"is not an Armstrong Number"); } *Factorial using For Loop= { int number=5; long fact=1; for(int i=1;i<=number;i++) { fact=fact*i; } System.out.println("Factorial of "+number+" is:"+fact); } *Factorial using While Loop= { int=5; long fact=1 int i=1; while(int i<=number) { fact=fact*i; i++; } System.out.println("Factorial of "+number+" is:"+fact); }
