I am trying to make a program that uses three digit numbers to identify items and I am trying to use something like the charAt method for integers or something. Im not too sure. Im a beginner and I apologize i just need help. Also I need a bit of help to use an if statement and relational operators. Im trying to do if the last digit in the number is less than 5 then it is {item} and if its greater than 5 then its this {item}. Something like that. Thank you so much in advance.
String number;
System.out.println("Enter three digit number: ");
number = in.nextLine();
switch (number.charAt(0))
{
//stuff
}
if (number > 5)
{
//it is this item
{
else
{
//it is the other item
{
There are at least two ways you can do it:
String number = in.nextLine();
char c = number.charAt(i); // i is the position of digit you want to retrieve
int digit = c - '0';
if you want to get ith digit from the end of an Integer, do:
int digit = 0;
while(i > 0) {
digit = n%10;
n /= 10;
--i;
}
