Iterating over a String to check for a number and printing out the String value if it doesn't have a number
- by wheelerlc64
I have set up my function for checking for a number in a String, and printing out that String if it has no numbers, and putting up an error message if it does. Here is my code:
public class NumberFunction
{
public boolean containsNbr(String str)
{
boolean containsNbr = false;
if(str != null && !str.isEmpty())
{
for(char c : str.toCharArray())
{
if(containsNbr = Character.isDigit(c))
{
System.out.println("Can't contain numbers in the word.");
break;
}
else
{
System.out.println(str);
}
}
}
return containsNbr;
}
}
import com.imports.validationexample.function.NumberFunction;
public class Main
{
public static void main(String[] args)
{
NumberFunction nf = new NumberFunction();
System.out.println(nf.containsNbr("bill4"));
}
}
I am trying to get it to print out the result to the console, but the result keeps printing multiple times and prints the boolean value, which I do not want, something like this:
bill4
bill4
bill4
bill4
Can't contain numbers in the word.
true
Why is this happening? I've tried casting but that hasn't worked out either. Any help would be much appreciated.
