ICSE − Q & A

int z=148;
 while (10>9)
 {
 if(z<139) 
break;
 System.out.println("computer" +z);
 z=z-3;
 }System.out.println(z);
 How many times the loop will execute ?
What is the output?

All the best!

Is it necessary to use public for function prototype questions
ex:can we write float sum(int x) instead of public float sum(int x)

Hope rises like a phoenix from the ashes of shattered dreams.

Is this the correct format of writing a number program using method? , if not send me the format Thank you... 

import java.util.*;
class Niv
{
    public static void main(String args [])
    {
        Scanner in = new Scanner(System.in);
        System.out.println("Enter a number");
        int n=in.nextInt();
        int num=n;
        int sum=sumOfDigits(n);
        
        if(num%sum==0)
        System.out.println(num+" is a Niven number");
        else
         System.out.println(num+" is not a given number");
          
         
        }
        
        
        public static int sumOfDigits(int g)
        {
            int sum=0;
            while(g>0)
            {
            int rem;
            rem=g%10;
            sum=sum+rem;
            g=g/10;
        }
        return sum;
        
        
        
    }
}

Why is an object called a static data member??

can anyone tell me the problem with this snippet as I am not getting my output.
Purpose:
to enter 10 names of cities and their populations:
import java.util.Scanner;
class cit_pop
{
    void main()
    {
        Scanner in=new Scanner(System.in);
        System.out.println("Please enter the names of 10 cities and their populations:");
        int p[]=new int[10];
        String c[]=new String[10];
        for(int i=0;i<10;i++)
        {
            System.out.println("Please enter the names of cities and their populations:");
            
            c[i]=in.nextLine();
            p[i]=in.nextInt();
        }

anyone who can upload physical education specimen paper 2018...
