Question

6. Write a method that meets the requirements of the following comment header block.

//

// isMultiple

//

// The purpose of this method is to find whether or not the first

// integer provided is a multiple of the second integer. In other

// words, when the first integer is divided by the second, is the

// remainder zero?

//

// Input Argument: a the first integer

// b the second integer

// Return Value: multiple a boolean value representing whether or not

// the first integer is a multiple of the second

// 7. Write a method that meets the requirements of the following comment header block. This method should use the method created in the previous problem.

//

// findLastMultiple

//

// The purpose of this method is to find the last appearance of a

// multiple value within an array. When found, the method returns the

// index number of the value in the array. If a multiple is not found, the

// method returns -1.

//

// Input Arguments: values the array of values

// n check for multiples of this number

// Return Value: index the index of the final multiple in the array,

// or -1 if no multiple is found
