This program you will learn how to use both conditional and looping constructs in a nested format, that is a conditional statement would be present inside a for loop. As mentioned in other articles, there would be several ways to write logic for any problem / program, here I am showing some of the simple ways to solve the program.

Way 1 – using a “for” loop


import java.lang.*;

public class PrintEvenNumbers
{
    public static void main(String rs[ ] )
    {
        int targetEvenCount = 10;
        int currEvenCount = 0;

        // the below for loop will continue to run as long as the number of 
        // even numbers found are less than the target number of even numbers
        // you want to print. 
        for(int i=1;currEvenCount

Way 2 - using a "while" loop


import java.lang.*;

public class PrintEvenNumbers
{
    public static void main(String rs[ ] )
    {
        int i = 1;
        int targetEvenCount = 10;
        int currEvenCount = 0;

        // the below while loop will continue to run as long as the number of 
        // even numbers found are less than the target number of even numbers
        // you want to print. 

        while(currEvenCount

There are more ways, by creating a class and methods which can be called, the above program is also a way of writing a class writing the logic in a main method, but the predefined main method cannot be called by other classes. You may have to give a different method declaration other than the default main method provided by java. You will learn this in the tutorials which talks about creating classes and methods in java.
