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
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |
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<targetEvenCount;i++) { // This is condition which finds if current value in i is an even or not // if its an even number, currEvenCount is incremented by 1. if(i%2==0) { currEvenCount++; System.out.println("Even Number :" + i); } } } } |
Way 2 – using a “while” loop
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 |
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<targetEvenCount;) { // This is condition which finds if current value in i is an even or not // if its an even number, currEvenCount is incremented by 1. if(i%2==0) { currEvenCount++; System.out.println("Even Number :" + i); } i = i + 1; // increment the value of i to find the next even number } } } |
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.
