How can I print out 1-50 even numbers only, but the it start a new line every multiples of 10. (JAVA-CodePudding

I'm a newbie, but I'm willing to learn how to code.

I tried using this code:

int n = 50;
  int counter = 0;
System.out.print("Even Numbers from 1 to " n " are: ");
for (int i = 1; i <= n; i  ) {
   counter  ;
   if (counter == 2) {
    System.out.println(i   " "); 
    counter = 0;

== 0

to find all even numbers between 1 to 50 and make a new line at multiples of 10 just follow these steps -

Make one loop which will go 1 to 50
Check if the number is even by checking the remainder after diving it with 2, if YES print that number.
Check if the number is a multiple of 10 by checking the remainder after dividing it by 10, if YES make a new line

The code will look something like this -

 int i = 1;
    while(i<=50){
        if(i%2 == 0)    System.out.print(i   " ");
        if(i == 0)   System.out.println();
        i  ;
    }

Output -

2 4 6 8 10 
12 14 16 18 20 
22 24 26 28 30 
32 34 36 38 40 
42 44 46 48 50

It's up to you which looping method you want to use for me While loop looks cleaner. I hope this solves all your queries.

PFB Snippet:

public class Main
{
    public static void main(String[] args) {
        for(int i=1;i<=50;i  ){
            if (i%2 == 0) //Check whether number is even 
            {
                System.out.print(i " ");
                if (i == 0) // Check if it is multiple of 10
                {
                    System.out.print("\n");
                }
            }
        }
    }
}

Output:

2 4 6 8 10 
12 14 16 18 20 
22 24 26 28 30 
32 34 36 38 40 
42 44 46 48 50

"\n" is a Escape Sequence which means new line
