Hello Sirs, good day....I am new to java and i have some little difficulty of solving simple java programs...

I have an activity and it requires a 50 integer for loop and when ever an integer is divisible by 3 it outputs Hello , if its divisible by 5 it outputs world , if it is divisible by both 3 and 5 it outputs Hello World...the program should output

1
2
3 Hello
4
5 World
6 Hello
7
8
9 Hello
10 World
.....
15 Hello World

this is my code and i need help on where i am wrong...i would really appreciate it if anyone helps...thank you

import java.util.*;


class Exer13{
	public static void main(String[] args){

		Scanner sc=new Scanner(System.in);
		int i;
		for(i=1;i<=50;i++)
			System.out.println(+i);
			{

		do{
			System.out.println(+i+"  Hello World");
		}

		while((i%3!=0)&&(i%5!=0));

                 }

	}
}

You don't use sc anywhere, so delete it. In general it's not a good idea to declare variables unless (and until) you want to use them.

Consider using if statements instead of the do-while loop.

Also you need to sort your indenting out.
That might highlight a problem with your 'for' loop.

@CIT_Peter:

Here is one example how your code for solution of your problem could look like:

import java.util.Scanner;

public class Exer13 {
	public static void main(String[] args){
		 
        Scanner sc=new Scanner(System.in);
        int i;
        for(i=1;i<=50;i++) {
        	
        	System.out.println(i);
        	
        	if(/* integer is divisible by 3 - write your code here */) {
        		System.out.println("Hello"); // this is output Hello
        	}
        	else if(/* integer its divisable by 5 - write your code here  */) {
        		// output World  - write your code here 
        	}
        	else if(/* integer is divisable by both 3 and 5 output Hello World*  - write your code here */) {
        		// output Hello World  - write your code here 
        	}
        }  
	}
}

@CIT_Peter:
Here is one example...
[/code]

I don't think an if-else if chain will have the desired effect. And your sc is cruft in a situation crying out for care, precision and thought.

Possibly when (or if) the OP responds with some further thoughts and code we'll have more to work on.
