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;

}
