public class Program
{
public static void main(String[] args) {

int maxElements = 500;
String[] numbers = new String[maxElements];
String num = "";
boolean isSkipped = false;

// generate our fake numbers for testing
for(int i = 0; i < maxElements; ++i) {
numbers[i] = Integer.toString(i);
}

for(int i = 0; i < maxElements; ++i) {
num = numbers[i];
for(int j = 0; j < num.length(); ++j) {
if(num.charAt(j) != '3') {
if(num.charAt(j) != '4'){
isSkipped = true;
}
}
}

if(!isSkipped){
System.out.println(num);
} else {
isSkipped = false;
}
}

}
}
