Question

How can I return value in a for loop ? For example if I have a loop that give me 3 numbers: 1,2,3… How can I return the value of the last number (here it is 3)?

public class Cod { 
  public static void main(String[] args) { 
    exp(); 
  }
  public static int exp() { 
    int x=10; 
    for (int i=1; i<=3;i++) { 
      x=x*10; 
      int y=x/10; 
      System.out.println(y); 
      return y; 
    } 
  }
}

If I understood what you are trying to do, here is your example modified:

public class Cod { 
  public static void main(String[] args) { 
    System.out.println(exp()); 
  }
  public static int exp() { 
    int x=10; 
    for (int i=1; i<=3;i++) { 
      x=x*10; 
    } 
    int y=x/10; 
    return y; 
  }
}

I don’t understand why you do x/10 – instead you could just loop one less round.
