Write a method that receives an array of integers as its parameter and modifies

Question

Write a method that receives an array of integers as its parameter and modifies the contents of the array, by adding 1 the even values and subtracting 1 from the odd values. Example: If the array contained {37, 25, 19, 67, 82} then when the method returns the array contents would be {36, 24, 18, 66, 83}. Your method should work for an array of any size. Be sure to declare any local variable you may need. public static void modify (int[] list) {}//end reverse Write a method that receives an array of integers (o any length) a its parameter and returns true if the array contains no even number, otherwise it returns false. Example: If the array sent to it is {35, 17, 23} it returns true, the array is {29, 34, 13, 56) then it returns false. public static boolean hasNoEven(int[] arr) {//end method show the output from the following program fragment. public static void main(String[] args) {int[] arr = {34, 25, 67, 29, 12}; modify (arr); printArray(arr);}//end main Public static void modify (int[] arr) {for (int k = 0; k

Explanation / Answer

Q4

public static void modify(int[] list){
       for(int i=0;i<list.length;i++){
           if(list[i]%2==0)
               list[i] = list[i] + 1;
           else
               list[i] = list[i] - 1;
       }
   }

Q5 public static boolean hasNoEven(int[] arr){
       boolean flag = true;
       for(int i=0;i<arr.length;i++){
           if(arr[i]%2==0){
               flag = false;
               break;
           }
       }
       return flag;
   }
