Armstrong number in Java. Here we have written the code in four different ways standard, using for loop, recursion, while loop and also with different examples as like: between 100 and 999, between 1 to 1000 and between 1 to 500 with sample outputs and online execution tool embedded.

Example Java armstrong number

public static void main(String[] arg)

{

int i=100,arm;

System.out.println("Armstrong numbers between 100 to 999");

while(i<1000)

{

arm=armstrongOrNot(i);

if(arm==i)

System.out.println(i);

i++;

}

}

static int armstrongOrNot(int num)

{

int x,a=0;

while(num!=0)

{

x=num%10;

a=a+(x*x*x);

num/=10 ;

}

return a;

}
