There are 4 things you need to understand to do this: - n%10 gives you the ones column of any number, - n/10 shifts the tens column and beyond down to the ones column, - n*10 shifts the ones column and beyond up to the tens column, and - n+d puts a digit d into the ones column assuming it is empty. Such as: 23%10=3 23/10=2 3*10=30 30+2=32 Put together correctly in a loop until the original number is zero and the result is a reversed number.

class Reverse { public static void main(int n) { int s=0; while(n!=0) { s=s*10+(n%10); n/=10; } System.out.println(s); } }
