Java Programming

[Gandalf14141]

I'm currently taking a Java programming class in college. I have the following 2 problems that I just can not figure out.

 

1. Given two variables number and lsd of type int, write an expression that assigns the least significant digit of number of lsd. For example, if number is 567, then lsd should get a value of 7.

 

and

 

1. Given two variables number and secondDigit of type int, write a code fragment so that the variable secondDigit gets the second digit (from right) of number. For example, if number is 56487, then secondDigit should get a value of 8. [Remark: You are allowed to write multiple Java statements. However, there is a way to achieve this by just one Java statement. ]

 

I have searched and have gotten nowhere. If someone would be able to at least guide me in the right direction I'll be able to handle the rest.

 

Thanks!

 

EDIT: I'm not asking for anyone to do it for me, I'm just asking for something so I'll be able to figure it out.

 

EDIT2: I figured out the first one.

public class numberfive {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
int number;
int lsd;

number = 567;
lsd = number%10;

System.out.println("Least Significant Digit = " + lsd);


}
}

First one:

 

lsd = number%10;

 

Second one:

 

secondDigit = (number/10)%10;

 

The second one you just divide by 10 to make the 2nd to last digit the last digit.

Ah. Thank you very much! That makes sense! I was stumped so I was hoping someone would be willing to help on here.

You could also get the length/count and extract the number that way.
