ICSE − Q & A

whats the difference between a method and a function

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?

Can anyone pls... Explain me selection and and bubble sort program with the help of dry run

If you want to practice output prediction question, here's the link --->

I hope this will help :D
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;
        
        
        
    }
}

Anyone have together with biology notes...pls share with me drive link or mai me..(CH:reproduction, nervous system and genetics..)


..pls

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();
        }
