Question

write code to count the number of odd integers in an array of 100 random integers in the range [0,99].

Answer 1

import java.util.Random;
public class OddNumbers{
//code to count the number of odd integers in an array of 100 random integers in range 0-99
public static void main(String []args)
{
Random r=new Random();
int count=0;
int[] arr=new int[100];
  
for(int i=0;i<100;i++)// loop to generate random numbers in range 0-99
arr[i]=r.nextInt(100);
  
for (int i=0;i<100;i++) // loop to check odd test for 100 numbers
{
   if(arr[i]%2 != 0)
    count++;//to count if a number not divided by 2
}
System.out.println("number of odd numbers="+count);
}//end main
}//end class

//output generated

$javac OddNumbers.java
$java -Xmx128M -Xms16M OddNumbers
number of odd numbers=53
