Program Plan Intro

Program plan:

printRandomIntegers.java

• Create a class named “printRandomIntegers”.
  • An integer array named “val” has been declared with size “10”.
    • Using “for” loop, computed and filled the array “val” with 10 random values between “1” and “100” using “Math.random()” function; also the output varies every time the program is executed.
  • Iterate through the “for” loop and find every element of random values present at even indexes by incrementing value “x” by “2”.
    • Print the elements present at an even index position.
  • Using the loop “for (int x = 0; x < val.length; x++” find and compute even elements in “val” array.
    • Inside the “for” loop, a conditional statement “if (val[x] % 2 == 0)” checks whether “val[x]” is divisible by “2” or not.
    • If the condition is true, then it prints the even elements.
  • Using the “for” loop, reads all the ten random integers from the array “val”.
    • Inside the loop, the print statement prints elements in the “val[x]” array at each iteration in reverse order.
  • At last, the print statement prints the first “val[0]” and last element “val[val.length – 1]” of random values from the array “val”.
