Unit 6: Lesson 2 - Coding Activity 1 AP Computer science
sladkih [1.3K]

The complete program is to define a boolean method that returns true if all elements of an array are negative, or return false, if otherwise

The method in java, where comments are used to explain each line is as follows:

//This defines the method

public static boolean chkNegative (double[] myArr) {

   //This initializes a boolean variable

   boolean isNeg = true;

   //This iterates through the array

   for (int i = 0; i < myArr.length; i++) {

     //If the array element is 0 or positive

     if (myArr[i] >= 0) {

         //Then the boolean variable is set to false

       isNeg = false;

       //And the loop is exited

       break;

     }

   }

   //This returns true or false

   return isNeg;

 }
