Given Code To modify:

LengthMismatchException Class:

public class LengthMismatchException { } VectorM Class:

public class VectorM { public VectorM(){} public VectorM(int size) {

} public int size() {

return 0; } public int dot(VectorM v) {

return 0; } public VectorM add(VectorM v) {

return null; } public void set(int idx, int value) {

} public int get(int idx) {

return 0; } }

LengthMismatchException The must be modified to be an unchecked exception. You must extend the appropriate class and write the two constructors discussed in class. Note that no tests will run before you complete this portion of the lab Non-default constructor The non-default constructor in Vectorm takes a size. You will need to create a new array of ints with the specified size and store the reference in an instance variable (that you will need to create in the class). You may do any other initialization you think you need in this constructor as well. size, get, and set The size method should return the length of the array that is stored in the The get(int idx ) method should return the value at the index that is the parameter. Don't worry about bounds checking the index; the IndexOutOfBoundsException that would be thrown in the event of an index that is too large or too small is sufficient. The set(int idx, int value) method should set the array at the specified index to the specified value. The dot method The dot product of two vectors is a single integer. It is calculated by taking pairs of numbers with the same index in two vectors, multiplying them, and then adding all of the resulting products together. For example, if I have the vectors [2,4,5,8] and [1,3,6,0], the dot product would be 21+43+56+80=44. If the vectors do not have the same size, you should throw a The add method The result of adding two vectors is another vector of the same size. The value at index i of the resulting vector should be the sum of the two original vectors at index i. For example, if I have the vectors [2,4,5,8] and [1,3,6,0], the sum of these vectors would be [2+1,4+3,5+6,8+0]=[3,7,11,8]. If the vectors do not have the same size, you should throw a
