Answer:

Java Program to print Even numbers from 1 to n or 1 to 100

By Chaitanya Singh | Filed Under: Java Examples

In this tutorial, we will write a Java program to display even numbers from 1 to n which means if the value of n is 100 then this program will display the even values between 1 to 100.

Program to display even numbers from 1 to n where n is 100

In the following example we are displaying the even numbers from 1 to n, the value of n we have set here is 100 so BASICALLY this program will print the even numbers between 1 to 100.

If an integer number(never a fraction number) is exactly divisible by 2 which means it yields no REMAINDER when divided by 2 then it is an even number. This same logic we are using here to find the even numbers. We are looping through 1 to n and checking each value whether it is evenly divisible by 2 or not, if it is then we are displaying it. To understand this program you should have the basic knowledge of for loop in Java and if statement.

class JavaExample {

  public static void main(String ARGS[]) {

int n = 100;

System.out.print("Even Numbers from 1 to "+n+" are: ");

for (int i = 1; i <= n; i++) {

   //if number%2 == 0 it means its an even number

   if (i % 2 == 0) {

 System.out.print(i + " ");

   }

}

  }

}

Output:

Even Numbers from 1 to 100 are: 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 52 54 56 58 60 62 64 66 68 70 72 74 76

78 80 82 84 86 88 90 92 94 96 98 100
