Output string after evaluating numbers in int-CodePudding

I'm currently trying to print a string for each instance of 3 specific numbers (3 to Pim, 5 to Pam, 7 to Pum) in a number that might be present after user input (EX: Input: 1052373 Output: PamPimPumPim). I tried converting the number to a string and using .contains method but it isn't working. The other part of the code checks if the number is divisible by 3, 5 or 7 and outputs in the same way, and it works fine. Help's appreciated!

package pimpampum;
import java.util.Scanner;

public class PIMPAMPUM {

    public static void main(String[] args) {
        System.out.println("Introduza um número:");
        Scanner input = new Scanner(System.in);
        int x;
        x = input.nextInt();
        String y = x.toString();
         if(x % 3==0){
             System.out.print("Pim");
        }
         if(x % 5==0){
                 System.out.print("Pam");
        } 
         if(x % 7==0){
                 System.out.print("Pum");
        }
         if(y.contains("3")){
                 System.out.print("Pim");
        }
         if(y.contains("5")){
                 System.out.print("Pam");
        }
         if(y.contains("7")){
                 System.out.print("Pum");
        }
    }
}

CodePudding user response：

In order to print appropriate word for digits 3, 5, or 7 contained in the input number, just iterate the characters upon converting the number into a String:

int x = input.nextInt();
String y = String.valueOf(x);
for (char c : y.toCharArray()) {
    String code = switch(c) {
        case '3' -> "Pim";
        case '5' -> "Pam";
        case '7' -> "Pum";
        default  -> "";
    };
    System.out.print(code);
}
System.out.println();

For the input 1052373, the code above prints:

PamPimPumPim

for ..5.373, the rest digits are ignored.

CodePudding user response：

I think what you need to do is a While to iterate the numbers.

I present my solution to your problem.

From what I understand about your question, the additions I made to your code seem to me to be adequate for that.

I would like to point out that a little Google search would quickly solve your problems.

        String y = String.valueOf(x);

        LinkedList<Integer> stack = new LinkedList<Integer>();

        while(x > 0){
            stack.push(x % 10);
            x = x / 10;
        }

        while ((!stack.isEmpty())){
            System.out.println(stack.pop());

         if(x % 3==0){
             System.out.print("Pim");
