Overturn of number Java Basic

[mikestechs]

Hello guys, i just want to ask you... how can i write code that will do this: User put some numbers (for example 123) and code will return 321.. i need to do it in Do-While cycle.. only thing that i know about this is that i can use 123% = 3 and then 12% = 2 .... 1% = 1 and than get it somehow together.

The three things you need to know are

// Drop last digit from x
x / 10

// Get last digit from x
x % 10

// Add another digit to x
x * 10 + y

I'll leave the rest for you to figure out.

int s = 0;
while(x)
{
s+=x%10;
x/=10;
}

And s will store your result. The x variable gets consumed in the process though.
