To print even numbers in java?

Answer 1

final int limit = 1000000;

// Print evens...

for(int i = 0; i <= limit; i += 2) {

System.out.print(i + " ");

}

// Print odds...

for(int i = 1; i <= limit; i += 2) {

System.out.print(i + " ");

}

Answer 2

public class Test {

public static void main(String[] args){

for(int i = 0; i<100; i++){

if(i%2 == 0){

System.out.println(i);

}

}

}

}

OR

public class Test {

public static void main(String[] args){

for(int i = 2; i<100;i+=2){

System.out.println(i);

}

}

}

Answer 3

public class forloop {

public static void main(String args[])

{

for(int i=50;i<=80;i++)

{

if(i%2==0)

{

System.out.println(i);

}

}

}

}

Answer 4

// finds this sum in range (1, 100]

int sum = 0;

for(int i = 2; i < 101; i+=2) {

System.out.println("Adding : " + i);

sum += i;

}

System.out.println("Sum : " + sum);

Answer 5

Use a for loop, and increment two at a time. Something like this:

sum = 0;

for (i = 1, i <= 100, i += 2)

sum += i;

Explanation: "i" starts at 1, the loop continues running (and adding to the sum) while i is less than or equal to 100, and i is incremented two at a time.
